I bought a ClassD amp mainly because I wanted an amp I could lift. I was dubious at first but took the plunge and got a Nord Purifi dual mono Class D with Spargo op amps putting out 250wpc. I got a huge surprise when it had burned in for about 100 hours. It was dynamic, open with a solid bass and transparent without glare. My conclusion was that it was as good if not better than any amp I have owned including some ARC, Rogue, EAR and Krell models. As you seem to be in the Uk call Colin North the CEO at Nord Acoustics. He is knowledgeable and easy to talk to and has models well within your price range. Ignore the Class D naysayers on this forum and try Class D for yourself.
Should I steer clear of class D amps
I’m finally upgrading my amp. I currently have an Onkyo TXNR 636 which has served very well but it’s now the weakest component in my system.
I’ve a budget of up to £1200-£1300 and been looking at the NAD C3050.
I was initially drawn to the NAD C3050 when I saw the VU meters but these are not deal breakers if I can get a much better amp without them, but I really do like them. I spoke with a dealer and he mentioned all NAD amplifiers are now class D and that’s now where I’m stuck procrastinating my purchase. My understanding was class D never really took off, despite the power efficiency due to the HF noise caused by the PWM. Times change things improve but I can’t find much about how they have mitigated this, in fact an article in EETimes refers to how the tests performed for THD etc are quite irrelevant in a digital amp and quoted figures may be very different in real life. In essence, the way of testing makes them look better than they are. This may be true but do they sound good? We all know vinyl is technically an inferior medium but I certainly prefer it’s sound.
I am listening to classic/ heavy rock and a mixture of lossless streaming from a NAS into a Cambridge Audio CNX V2 and vinyl off a Technics 1500C with a Pro-Ject DS phono stage all into monitor audio bronze 5s.
I need a new amp. I need slapping out of my indecision but it’s not an insignificant amount of £££ and I want to get it right. Should I stick with AB ? My electric bill can’t withstand class A or valve regardless of sound quality.
Also what’s the thoughts on NAD in general, I’m my youth they were good amps, but then so were Pioneer.
