S150
The best thing I did was to buy this system. Simply put, the sound is fantastic, that’s what it’s all about. Great lads creating a British product to be proud of. Just try the amps, you won’t return it. The system: P50 MKII Passive Preamplifier / S150 Stereo Power Amplifier / Balanced Mains Unit / Rogers speaker / Cyrus CDi. Keep up the good work!

I hadn’t appreciated how much bigger and heavier the S150 is compared to the S80, it’s built like a tank. I’ve just unboxed it and put it into the temporary setup I’m running, not bi-amped but just as a straight swap – what a difference, drums have more punch, notes decay for longer, it’s astounding. Looking forward to lots of fun going forward, wishing you and the team all the festive best.
 
S150
So I ordered and received the new kit and plugged it in earlier this week. I have Royd Minstrel Loudspeakers (a "new" addition which are a massive improvement over my previous EPOS M5s), LS3 cable (I think), and sources being a Rega Planar 6 , and an Onkyo 6130 network player plugged into a Rega DAC. My reaction in the first 10 minutes was that it sounded brighter than I was used to, harsh even. I thought I might have made a mistake. I went to make myself a coffee and let the amp warm up. After an hour or so I came back in. I sat down. I played various different tunes representing all the genres. The harshness I perceived was gone. The sound was fuller, beefier, with much more defined bass than my AP 30. There seemed was more space between the instruments. I felt connected more than I ever had before. I went to bed relieved that I had not made a mistake after all. Over the last week I can't stop listening. It seems to get better and better. I don't know how a couple of simple black boxes can set my spine tingling or make such a difference but they do. Words I would use to describe include transparency, space, engagement, attack, emotion. I am so happy I went with NVA again and am absolutely delighted with my purchase. One day I will tell my wife what the money was spent on...
 
S150
I recently purchased the above items which have replaced a JVC AX441 amp and Van Damme speaker cable. The source, a Project RS Box cdt, Calyx 192 dac running into NVA Cube 3 speakers. Firstly let me say I normally don't like to dissect the music and tend to listen to the music as a whole. I have listened to rock, jazz, female vocal and guitar oriented music and on everything the music has been detailed in a non fatiguing way. Small details at the back of the mix seem more prominent, this was very evident on Acoustic Alchemy - Back on the Case, with tiny percussion strikes being heard far more clearly. Vocals on Mary Black - Babes in the Wood were so expressive and the piano on the title track really sounding like a piano. Listening to Yes - Keys to Ascension, on Awaken, Steve Howe's guitar although forward in the mix just came through clearer than I remember, this track is possibly my favourite Yes song but made far more enjoyable now. To finish, the best way I can describe how this system sounds, the music just flows.
 
S150
I thought it was about time I gave my impressions of the NVA kit I have. I bought the NVA Phono1 first, which started me on this great journey. Next came the NVA P50sa and NVA A60 Mk2, before these I had used amps from Naim, Arcam and Primare, nothing comes close to touching the N.V.A kit for all round musicality, it just seems sooooo right. I then upgraded the speaker cable from Chord Epic to NVA LS3 which was a step up in sound quality, I also changed all my interconnect cables to SSC which made a really big difference to the quality of sound and the size of the sound stage.
 
S300
When I made the step up to the S300 amp after first treading down the NVA path with the starter bundle, I couldn’t quite bring myself to part with the little S80 amp even though I had no immediate use for it. Well, the NVA blog on bi-amping soon changed that. Turns out there was an avenue I’d not considered travelling before - and that keeping the S80 had been an unintentionally inspired move. Using LS5 to connect the S300 to the woofers and LS3 to link the S80 to the tweeters has transformed my Rega RS5 speakers. I’d expected a subtle lift in performance but the difference has verged on the transformative. The bass has gained several layers of depth and presence, while the treble is revealing details I’d simply not heard before in much-loved recordings. Both amps were superb on their own terms - but working in tandem takes them both to another level entirely.
 
S300
It all started when the curiosity to try something new combined with the temptation presented by the P50/S80 starter system. I owed it to myself, I thought, to give it a try. And hey, I could always get my money back if it wasn’t a serious improvement on the old amplifier. Little did I know what a revelation those two acrylic boxes would be. An order for the Phono 1 followed pretty soon - I needed to hear what I’d been missing from the vinyl collection. A lot, it turned out. I was happy. But the thought started to grow - if the S80 sounded so good, what would the S300 be like? No, I couldn’t - the extra power would be overkill. But the seed had been planted. I needed to know so succumbed to curiosity again and placed the order. It arrived. Blimey, weighs a ton. What does it sound like? The S80 but so much more. More weight, more heft, more presence, more detail. What a fantastic amplifier. I’m very happy once again.
 
M300
My expensive valve integrated went pop so decided to buy a temporary replacement and plumped for NVA P50SA, M300's, SSP mkII, LS5. The rest of my system is a Kuzma Stabi R, Viv Labs Rigid Float 9 ", Ortofon SPU ROYAL N, Thomas Mayer D3A partial silver phono stage and Tannoy Arden Legacys. I am not going to spout off, but all I can say in my opinion it sounds fantastic, musically engaging, detailed, dynamic, bass is weighty and detailed, and when my integrated is repaired it will be sold. To add further credence to the above, a friend came round who is not into hifi but loves music, said he thought it sounded better than my integrated. I have just acquired a P50SA Mk2 and another pair of M300's for bi-amping. I will try the pre tonight and report back, and when I have sorted the extra sockets and a pair of LSTS speaker cables I have ordered for the power amps I will give a further update.
 
M600
I'm very happy to report that the M600s are sounding great and a big step-up from the A80 Mk1s. I must admit I was surprised by how much of an improvement I'm hearing, having always assumed that the A80s would never need replacing. I'm delighted with the new amps and amazed at the enhanced detail, separation, dynamics, presence, etc. They are clearly allowing the system to perform at its highest level so far, perhaps with more to come as they settle in. They also look great side by side in the rack, better than stacking the A80s for lack of shelf space. Thank you for a fantastic new product. I look forward to future developments with interest!

I had a windfall from the tax man and managed to acquire a P50 second hand for upgrading. This gave me a top of the range NVA system as shown above and I declared it as my 2020 ambition in one of the threads here (I've quite forgotten which one). These are initial impressions as the kit arrived at lunch time today. My expectation varied from "this is going to start out excruciating until it settles down" to "it's not going to be any better than my kW550". Well, wrong on both counts. Music all the way - yes the definition is there, the stereo image to die for, the big, well defined bass when called for. But it is a simply a pleasure to listen to it either intently or as background. I couldn't be happier. Audio Nirvana. It's simply a joy to listen to. Expensive? - yes. Value? - priceless. If it improves more it's going to be orgasmic!! Watch this space. 😁 😁 😁 😁 😁 😁 😁 Blusound Vault 2, P50SA, A80's, BMU, TIS, LS7, MA PL200.

With the BMU and LS6 in place and transforming the sound of my system, NVA amplification was the next step. The differences are not subtle. Familiar tracks which start slowly and build up have gained a new lease of life. Bowie’s “Rock n’ roll suicide” is a prime example, from the single acoustic guitar accompaniment at the start to the frenzy at the end. This effect was similar on his more mellow “Hunky Dory” album. When electric guitars came in, and acoustic guitars are strummed harder, things livened up, the effect was very pronounced. The clarity and separation on backing vocals have also taken on a new dimension. This was very evident on “Dark side of the moon”. I had not been aware that so much was going on. Heavier material also sounds a lot better. On Led Zeppelin’s “Physical Graffiti”, the simple riffs many of the tracks are based upon remain solid and stable as other guitars and keyboards enter the mix. In addition the power, as well as subtlety, of John Bonham’s drumming came across as never before. The Rush album “A Farewell to Kings” was also a revelation and increased my appreciation of Geddy Lee’s bass playing. His screaming vocal at the end of “Cygnus x1” (some of the lyrics in my signature) was handled with ease. The NVA kit revealed subtleties in Iron Maiden’s “seventh son of a seventh son” album which I was not previously aware of, beneath the layers of power chords. My only regret is that I was not aware of NVA sooner.

I first noticed the NVA P50SA / M600 monoblocks in the review by A British Audiophile. A friend of mine had been telling me for years to go for monoblocks and this review did it for me. I have been enjoying my Sugden A21SE line amplifier for a couple of years but I yearned for more clarity. I am a choral/orchestral conductor and wanted the sounds of my system to match what I hear in real life. When it all arrived, the amps took a little while to settle but this had been drawn to my attention already by Paul at NVA. After a couple of days the sounds were stunning - the fog had cleared and the pin sharp clarity of everything came so clearly into focus. What in the past had sounded 'like a piano' now was 'a piano' and Paul's promise of wanting to listen to music into the wee small hours was true. I immediately fished out my favourite recordings and listened to them afresh. It is almost like monoblocks are the equivalent of our two eyes, working independently but allowing the brain to sort out the image. An integrated amplifier is like seeing everything with our eyes crossed. I urge anyone who is serious about sound to order this combination asap! DAVID TEMPLE MBE www.davidtemple.co.uk

Steve. T. on Dec 08, 2023
I originally purchased an NVA S150 amplifier with a view to eventually having it upgraded to an S300. However, after some thought and a hankering after a pair of Mono Blocks, I got in touch with Paul with regards to the upgrade scheme. A price for my S150 was agreed and I put in an order for a pair of M600’s. My thinking was that the S150 was a very capable amplifier but M600’s would be at least a moderate improvement both in detail and weight. Well, I was wrong on both counts, the improvement was huge, the bass is deep and controlled not rumbling but sharp, detail has enhanced clarity in rise and decay of notes, and very natural sounding. My speakers really come to life now even at moderate listening levels, so pleased I made the jump.
 
M600
After 30 years of audio enjoyment, a mixture of curiosity and equipment failure suggested a change was in order. Faced with a wealth of choice, I couldn't help but think about NVA as I'd long been captivated by their looks and intrigued by their ethos. Needless to say, the 30 day trial was an appetizing entryway and the selected items soon arrived (P50SA pre, M600 monos and P1 phono). Communication with Paul and team was first rate as too initial impressions of sound. Minus the usual hi-fi parlance, I can just say it sounded detailed, captivating and highly enjoyable. This sentiment has been shared by all who've listened to date. No matter the genre, the system shines and this has only developed as further NVA items have been added (Cube 1s, upgrade in cables and power supply). So here we are, 30 years in with both vinyl and CD sounding fabulous and shedding new light on many a recording.
 
M600
On the Saturday night before the M600’s arrived I had been talking with a friend about how I might never need to upgrade the starter system, as it is that good. Just so musical. But then a pair of M600’s on E-bay – advertised as B-grade from the manufacturer. Apparently a small mark on the casework, otherwise new. Too good to miss. Well the first thing to notice is that music just flows from these lovely amps - it seems an NVA family tradition. But there is more than that...Day 1 listening out of the box a twinge of buyer’s remorse, maybe they were not so much better than the A20 amp they replace. But day 2, and they have started to open up. Sat here listening to OK Computer, an album I like on vinyl but never could quite relax into the digital version, but now I am back in time and finally my digital front end is singing. Click through albums and Its probably been thirty years since I have heard Wish You Were Here as I loved and remembered. So - this is just sublime, I usually just about tolerate Sledgehammer, but with the inner detail all revealed it’s awesome ……… listening through a selection. 5 hours later, what can be said ? Speechless, no listener fatigue, first impression’s beyond reproach. Bass lines clear, vocals clean, snares crisp, no sense of harshness, heaven. The NVA starter system is amazing value for money, but these amps are a helicopter ride to the top of the mountain. Pretty much my end game complete.
 
S150 TO S300
This is a bit of a follow on as I started out with the S80 before using the trade in scheme to move on to the S150 for more power and eventually upgrading that to the S300. Since this is all subjective I should say what other components I use so my pre is a refreshed NVA P80 with MM phono stage and separate power supply, Kralk Audio BC30 MK2's, Topping D30 Dac, Audiolab CDT6000 and Project Debut Carbon DC with Ortofon 2M Blue.

In some ways there is little to say that isn't already said online in the descriptions, the S80 is fantastic with 90dB+ speakers but will struggle with harder to drive speakers. I have some 85dB speakers and while the S80 didn't get hot it was clear more power was needed to drive these speakers which now sounded bass light. I upgraded to the S150 which made a clear difference but upgrading to the S300 really pushed them to their full potential.

With regard to sound, I always call it the magic which is mostly clarity, realism and imaging. When I first got the S80 it changed what I thought solid state was capable of giving, made my tube amp virtually redundant and completely switched me off from the seemingly never ended path of trying to build the best hifi system I can within my budget.

I couldn't live without an S80, it's a sweet sounding amp so now I use a pre-owned S80 (bought from NVA) to power my 90dB Kralks and my S300 powers my 15'' semi U-frame OB subs.

The S150 carries the same clear open sound of the S80 but will drive less sensitive loads easier, it's really the same for the S300 and no doubt the mono blocks. There is no suspiciously magic upgrade path here where the manufacturer promises you better components or more complex tech, you get more power and that gives more dynamic ease which is more noticeable with difficult loads. All three of these amps stand out as being very musical and engaging which is no doubt partly down to the purist design of the amplifier boards.

I highly recommend an NVA matched system, especially if you're looking for your end game. Customer service and support has been excellent. Their finance options and trade in schemes have made it possible for me to build a fantastic system while their home trials allow potential customers to demonstrate without risk.
 
M300 TO M600
Just had a pair of M300's upgraded to M600's and let's just say I am a happy bunny. The M600's builds on the strengths of the M300's but with greater scale, dynamics, tighter bass, more detail and all this adds to the musicality. In conclusion if you are using M300's and have £500 to spare get them upgraded. If you don't use NVA even if you are using more so called 'exotic' kit and are wondering, then don't hesitate give it a try and you may be pleasantly surprised, I was, I did and I am.
 
A60 TO S300
Thanks for turning my A60 upgrade around so quickly; just one more example of your superb customer service. I thought I would drop you a short note to share my impressions of the new S300 configuration. To be honest, I wasn’t expecting a leap in performance – the A60 is a lovely amplifier – but a significant improvement there certainly is. My sound system has acquired a beautiful silkiness through the mid and top, and I wonder whether this may be due in part to the new power supply taking better control of the ribbon HF units in my Quad Z1 speakers. I can best describe the overall change as ‘less’ rather than ‘more’, in the sense that something has been taken away that was producing a subtle degree of impurity across the audio spectrum. New sounds in the back of the mix are discovered, distinct in placement, timbre and clarity. This amplifier is extremely revealing, as opposed to being ‘analytical’, if that makes sense. The old adage that “the wider the window, the more muck flies in” certainly applies, but this amplifier does not deal cruelly with less-than-perfect recordings; instead the open window lets the dust blow away. As an unexpected bonus, before the upgrade the A60 was prone to interference from the TV in the room below, which was cured by running the amp via a mains purifier unit. Now this sensitivity is gone and the purifier is redundant. I couldn’t be happier with the upgrade. Thanks for all you are doing to keep the NVA ethos alive and well.
 
A80 TO M600
I took advantage of the offer earlier this year to upgrade my A80s to MkIII spec and after a short wait for Tomasz to return to the UK a received them about four weeks ago. I really liked the A80s in their MkII but they where never silent to the extent that I had put them on isolating pads to reduce the hum being transmitted through the wooden shelf they were on, not a particular issue when listening but just an annoyance. The first thing was the total lack of hum in either the 'new' amps or the BMU, so much so that I wouldn't know they were on if not for the red LEDs. First listen was Rovo and System 7 Pheonix Rising, it sounded a bit constrained but I expected it to take a while to bed in so was not concerned. What was it really impressive was the space in the mix and also more texture to some elements. This has become a bit of a theme with more listening over the last few weeks as the tightness went but many tracks shone with coherence and again that extra texture which really pulls you in. I also noticed that there was seemingly more grunt, this may be just better resolution of bass lines but I am generally listening at slightly lower volume levels. This comes on the back of upgrading my P50 SA to the new spec last year and I have to say it is a real pleasure doing business with Paul and Tomasz, and the products are just great.
 
A80S TO M600
The upgrade to MKIII spec is not at all subtle. It's not easy to describe what's special about NVA amps, but for me it comes down to the way the sound fills space - it has a distinctive kind of presence, that's very natural and very addictive. It goes without saying that the amps have retained this quality, and so the NVA magic is still there. But otherwise it's like having a new set of amps - increased detail, better separation, better imaging, deeper and more controlled bass, higher and more detailed highs. The MKIIs were certainly no slouch in any of these areas, but still the jump to MKIII is significant and not at all subtle. And importantly, even with the more detailed highs, the sound is still as natural and unfatiguing as ever - I could (and will!) listen for hours. A couple of small points: The MKIIs emitted a quiet, but still noticeable hum. Likewse, the speakers when connected to the MKIIs would emit a quiet hum, noticeable when no music was playing. The amps and the speakers are now completely silent. Tomasz and Paul are clearly onto something with the MKIII component changes. I sent the amps in the new boxes, which worked very well, and the turnaround was speedy. Tomasz had clearly given the amps a good clean as well - they came back looking better than they went out. To sum up, the upgrade to MKIII spec is money well spent. Thanks guys! 😁
