Sorry to hijack the thread but how far does the Quad 909 go in class A? Some tens of mW?
I have a mate with a great pile of Carver amps, some of which he rates as the best he's had. He has I think the full set of Phase Linear (Flame Linear) amps that spend about as much time at the repairers as my car does in the garage. One day (Rodney) he is going to put them all together and build a huge cinema system, it's going to be 7.1, 9.2, or 11.2 depending on his mood, with piles of huge amplifiers. It may one day happen but I doubt it, I suspect that none of us ever really want to meet our heroes.That would be Carver with their Cube and other related amps. Not that brilliant sounding and prone to regular releases of the magic smoke! .
Well at least if he does, the explosions will be real!I have a mate with a great pile of Carver amps, some of which he rates as the best he's had.

So it's basically bias current x supply rail voltage = Class A power for a class AB amp?
I think he wants to do it so that he can tell people he has a 1kW per channel home cinema. He's still 3 months away from being able to get in that room, it's not going to happen anytime soon.RE, multi channel home theatre, I think it’s mostly had it’s day. I’ve had various setups over the years and invariably, I’ve gotten fed up with it after the honeymoon wears off, I can’t be doing with that many speakers in a room.
next week i hope to compare my humble arcam to a rather nice 11k hybrid integrated valve amp . we shall see how it goes
...
this is the guy i think
Yes I am using the irDAC with the MF M2si and really enjoying the combination with my Dali Oberon speakers. I found the irDAC is unusually rhythmic and has great timing and dynamics for an Arcam product and it’s refinement works well with the MF amplifier which is in itself very transparent (but not bright).
All three amps have a reputation of being excellent - so it's going to be tough. But an extensive listening session is called for so could take Months.
Zoom, those months went by fast; seems like it was only last Thursday.I have the original box, manual, leads, I didn't even use the power leads that came in the box, plus the remote. I know this isn't the classified section but I want no less than £365 plus delivery.

The Class G sound is very smooth yet detailed - I wonder how this would compare with a Sugden A21a? They are both pure class A at 25 Watts per channel.
There is no class G sound!! It is also VERY unlikely that this has much class A operation. As it seemed doubtful I googled the unit and neither Arcams brochure nor a What Hi Fi? review even mention it. The heatsink looks to small in photos as well.
Sorry yes of course - it's not a Class G sound, it's either a Class A sound or Class AB sound - depending on the power rail it jumps on to.
Interesting that you don't think is does much class A operation because of your assessment there isn't enough heat sinking in there - Arcam replied it runs on pure class A (yes that's 'pure' class A) up to about 20 - 25 Watts. I'm not sure how all this work - when transients require more than 25 watts in music - does the Arcam briefly jump rails then jump back again trying to keep it running in Class A as much as possible?
