Hi Steve,
The problem with the initial Elicit R which was running hot and started to sound inferior was down to the QC (quiescent current) being set too high, the Elicit R normally runs at a QC higher than other designs hence it feeling warmer to the touch (bearing in mind that the heatsinking is on the outside of the case then the case will always appear warmer than comparable amplifiers)
This has definitely had an effect on the sound quality and when the QC was adjusted downward and the amplifier was then compared to the reference amplifier then the differences were not at all audible.
Throughout this thread people have refered to Rega and our QC and I stupidly thought they were refering to Quality Control and not Quiescent Current 🙂 - this was a pathetic attempt at humour and should in no way be seen as us taking your problems lightly.

Paul - why are you making this public? this should be between you and Steve. And, no, contrary to what you might think I like Rega products, just that when I've tried to integrate them with my current set-up it hasn't worked for me. Nothing more, nothing less.

I think it's interesting. Not just technically, but also as a demonstration of openness and honesty (and lack of 'marketing spin' or BS).
Let's have Terry on here as well to talk a bit about amplifier design. I thoroughly enjoyed reading some of those links earlier (about how Terry Bateman was inspired by a stack of 1940s - 1970s Wireless World magazine articles to try and recreate elements of the sound from favourite old valve amps and early solid-state designs in a modern amp.)
Heck, let's not stop there. Let's get John Dawson back to the forum to talk about the A&R A60 and the modern amps he is still helping to design at Arcam. Let's get 'em all at it. Naim, Linn, Sugden etc. (even b####y Leema PP) and let's hear about the problems too.
