This is aimed at westie.
Did you say that you owned AP20 back in the 80's? Was it any good through your system at the time.
Just curious.

Back in the 80s I had a few Pre/powers including a pair of mono blocks.All were very good but I never really rated the phono stages that highly, even with multiple plus. I also had an AP30:or 35 which was good too. My AP20 was a metal cased one with very thin lacquered wires inside.

Thanks for clarifying.
Does NVA amps really have any sound character at all?. Sometimes I wonder.

Thanks for clarifying. Does NVA amps really have any sound character at all?. Sometimes I wonder. S. A reviewer once said they sounded simple and direct. I think that’s a good description. A tad bass light IMO but that’s not necessarily a bad thing. As they are all the same circuit, I find you get 95% of what’s on offer from the budget kit, unless you have insensitive speakers,

My father briefly had A80 MK2 Mono's. I wasn't very keen on them. Thought they lost some of the magic you get from the smaller amps. But who knows, could be my imagination playing tricks on me!

It's been said a few times elsewhere that the smaller Amps have the magic so you might be in to something

Did you cancel your order for the A20 in the fire-sale Shane?
Ask macca if you want an honest description of the sound of a smaller NVA amp - just seen the above comment - it's not as heavily coloured as macca portrays but it certainly ain't squeaky-clean-clinical either. To me over dozens of examples, it's utterly charming, involving and musical, painting the music in broad strokes, Rudi would love the total lack of any harshness or 'HiFi' glare and you can listen through an NVA for hours with no listener fatigue whatsoever! I find the current issue larger amps build on the smaller models sonically, offering some real audiophile clarity to the musical reproduction of the base models - Savvy should be able to confirm this. HOWEVER, the larger ones must not currently be used by a numpty unless the recommendations on cables and so on are strictly followed. Not sure what cables macca used - Chord Odyssey would not be a good choice at all in my experience.
Another word of caution worth repeating as so many owners, especially of the larger amps, ignored this at their reliability peril. Until now, no instructions have ever been provided, the thoughts being that owners, once they 'find' NVA, know what's what and are intelligent and thoughtful enough to follow the guidelines about speaker cables and so on. Sadly this hasn't been the case and although the smaller amps are almost tolerant, the larger ones currently aren't although plans were afoot to improve this!
Anyway, you don't want to know or hear what I'm telling you, but I'd suggest that few previous owners of NVA ever complained about the product itself and that includes serial box-swappers like yourself Shane. I'm going back over ten years on AOS for this. The man himself was another matter obviously.

Having only had one pair of A80s, I’m probably limited in my experience, but I thought they sounded very dull. Got rid asap. They were from a HFs member and hadn’t been messed with, so I really don’t know if they were typical. 4x A40 murdered them in my system though.

Same boards and output stage, so there shouldn't be any difference tonally. Not something I ever experienced at Sidcup when RD compared amps for me although I admit, the largest amps i ever had here were AP70's - my own larger home made amp uses AP70 size power supplies. My smaller one is configured as a dual-mono AP20 and this compresses in comparison, emphasising reverb and atmospheric effects as the A20 does a little (the magic 'everyone' loves including me).
Bi-amping always usually works well, regardless of amp maker.
What speaker cables were used?

I’d be tempted to think it was the Spicas benefitting from bi amping as they did have a complex crossover. The thing is, the little AP10PX was far livelier and more open than the A80s were. Maybe I got a duff pair. Any amp is only as good as it’s components and suppliers are just a sprint to bad batches as anyone, It was one of those times I’d expected an upgrade with no downsides......and wasn’t totally wrong. All history now, I guess,

I should add that in any description here, I’m the worst person to ask about whether anything is coloured, it’s not something I tend to value or am easily able to discern. I guess I don’t listen in that way, NVA has never sounded coloured to me, but then not much has,

The bigger amps (I have A70s and A80s) bring increased transparency, detail, separation, height, depth, width , dynamic ease.
I haven't lived with the 20 series at home but I heard them at length when I helped Richard & Tom with the Woodland Grange show. At 'domestic' volumes, with a speaker that is reasonably efficient and easy to drive then it might be all you need.
I don't detect any 'tonal tricks' being played, in either range of amps.
I find it a bit like the difference between big and small speakers. I was happy enough with the little ones, but heaven knows I'm much happier now...

If these differences are so audible, and using the same amp boards and output stage too, then any 'dullness' must be very easily measurable. I can't say more in any depth and currently it's academic. i would say though that the small amps compress like a Naim Nait mk1 used to. According to repeatable research the Beeb did decades ago, 'we' can tolerate up to 10db of compression before really noticing it and it's my view and experienced that really powerful gear does tend to sound 'dryer' than nicely clipping smaller amps and not always as 'nice' to start with. My two NVA home-builds tend to show this - the larger amp here sounded more like Maccas Krell in direct A-B comparison, but of course, a large NVA isn't a nice Krell, so the eyes would say it's nowhere near as good! The smaller amp delivers in a charming way that flatters the ears and that's how I find 'proper' production sounds as well, so I feel qualified to make the comments.
An AP20 is not 'placky cack' as described elsewhere. It can be a great amplifying 'companion' in a domestic music system and used as instructed, it should be very reliable.
Surprised you don't like LS5 westie. I find it very good here in 3m runs but then, I use LS2 successfully (mine is Ebion Kablo sourced) in the main system and in 8m runs too.

ime, NVA amps don't like to see complex crossovers. If the Spicas are such, then I could well imagine biamping the 2 pairs of A40 monos (so that each set sees 'less' crossover) would be an advantage over one set of larger monos.

LS1, 3 and 5 sound “broken” to me. I’ve tried a few sets because I couldn’t believe a cable which others rate could be so atrocious. Every time I’ve heard the same lack of presence and spatial information. In no way could this be regarded as subtle....they sound intolerably bad to me. I remember having a friendly back and forth with RD when I had the AP20 because I tried LS1 and then LS3 and found them vastly inferior to K20. His response was that K20 would cause no problems but he suspected one of us was deaf I have a feeling I’d love the more expensive cable used in TSCS because it works wonders in small amounts in LS6. Ultimately I still found LS6 wearing although it was detailed and didn’t have the issues I heard with LS1,3 and 5. Both old style and new style LS2 are decent cables too and will easily see off the competition. It clearly has a large subjective element though. Rudi and others love CS122. I think you’d get the same effect by buying ear muffs.

I’d already found stuff I liked better by that stage, so I just moved them on at £450 iirc. No complaints from the next owner, but then they did work, so I dunno if he got. A better result or not.

My LS5 'here,' is nothing as you describe westie but then, gauge can be everything here and the speakers I have almost certainly don't sound as yours do (I'm not having a go - we've discussed this many times). I don't like the silver plated stuff you seemed to like, even doubled up, as it sounded scrappy and ill defined the better the stereo got - fine for livening up a more basic system with a nice shiny 'treble' region though and I'm guilty of selling loads of the Chord Odyssey version.
These days for speaker cable, I just like the individual good-gauge install cable ideal, as long as the copper is good quality (some cheaper cables are copper plated aluminium and total shite, even as a general wire due to high resistance).

I know this shouldn't be posted in this section.
I'm possibly looking at maybe getting NVA 'Super Sound Cords' to use on my headphone system. Are the SSC shielded to reject hum etc?
Forgive my witless question here. Does the SSC have the potential to out perform interconnects costing in the £300-£350 region?

So the differences between the small amps and big ones (to try and explain some people's loss of the magic)
1) All use exactly the same amp boards, wire, case material
2) Transformers get bigger as you go up the range
3) Bigger capacitance in the psu (two caps in parallel in some cases)
4) There is an extra psu in the larger models so output stage gets a dedicated psu, so does the front end and driver transistors.
So could the dullness be due to too much power supply capacitance ? Or it must be the extra psu . It shouldn't be related to the larger transformer unless the stray field is causing problems. Larger transformer = lower impedance and i wouldn't have thought that would lead to a dulling down of the performance.
Or maybe people just like the sound of soft clipping ?

I've got three pairs of ssc and I'm not using any of them. Only half a metre long though.

I’d expect there will be a few expensive ones it will beat, but that’s because a price is what somebody decides to charge. It’s not a reflection of material cost or sound quality. It’s a decent cable but I’d be DIYing it for peanuts rather than paying for the made up version. I have way better cables (IMO) now, but that’s just my opinion and worth no more than anyone else’s. I dunno if a loaner is available, but you could always try Macca’s SSC against Spotfire. The latter was better in many ways for me, but it just lacked an extra sense of presence I got from SSC. In the end I got the Black Rhodium which did more than any other cable has.

I wouldn’t spend half my life fiddling with interconnects but I’m glad I had the last round of comparisons. Big losers were Klotz AC110 with Profi plugs and the white Isoda cable that Roksan like. It sounded like the throwaway ones you got given with cheap jap kit in the 80s. I quite liked the Audio Note AN-C but it wouldn’t compete with a top cable.
