PP, thanks, useful insights as always.
Richardw42 - I'd like to see if I can improve the sound quality and for me getting a better amplifier will do that. Also, amplifiers do have characteristics and it's not just about driving the speakers; a good amplifier and bad amplifier could drive the speakers but it doesn't mean they will sound good.
Drummerman, it's just a case of me wanting to improve the quality that's all. There is nothing bad/wrong with my NAD C350 amplifier; in fact, it's a very nice amp, I just think I can get better.
BigH, thanks - I'd heard good things about the Rega Brio R so I'll definitely add it - they say it's very musical and warm.
Fatman - thanks, seen this - great deal, great amp but it's silver and I need black, otherwise I would have gone for it.
richiesuk - KI Pearl - why did you prefer it over the K2 and Brio?
Bigboss is right btw - I'm just after general feelings towards these amps - I know it's not such an exact science and many other factors will come into play. But it helps to start off hearing the right amplifiers regarding the kind of sound I'm after - unless some of you have enough time to demo 25 different brands.
altruistic.lemon - thanks, I'd thought of this but I think I can get more out of my speakers than I can my amplifier.
busb and others - descriptions - we have to use them and of course they may mean something different to everyone but if we don't use any, then how can we convey what we hear?! I agree that clinical to one person could mean detailed to someone else. So be it, it's their interpretation. We need to use whatever words we feel describe what we're hearing.
pete321 - I'd also heard this about the Audiolab 8200a - it can be neutral, true, pure and smooth. I'd also say that my Audiolab M-DAC added smoothness to my kit, along with many other attributes.
