Do I esentially have a class A amp?

"Often amp with poor specifications has wonderful sound" so true.

Kijanki-Wow!! Thanks for all the information. I'll be honest, the Krell was a freebie so it doesn't hurt my feeling one way or the other. It sounds good even though the KST series of Krell amps get no love. I'll tell you from a pure synergy perspective I haven't heard a better amp than my Music Reference RM-10 through my Vandersteens. Sure 35 watts won't tear the walls down but for me it plays loud enough. When Roger Modjeski designed this amp he used my Vandersteen's and a pair of old Quads to voice the amp with. I always loved el-84 amps, my first amp was my Dad's Harman Kardon Ballad integrated and ever since I've been hooked. I'm sure my amp doesn't offer the best specs but for me it offers the best sound.

35W won't tear the walls but don't forget that 350W (that tears the wall) is only 2x louder. Also 3dB more sensitive speakers will give you same as doubling the amp power.

So, how your 35W amp compares with good 140W amp driving 3dB less efficient speakers? 140W amp will be only 22% louder.
People often ask if it is better to buy 200W or 100W amp. In spite of amp's power being useless specification IMHO, I would always choose 100W because for the same money I can buy better amp.

Kijanki, I enjoy reading your contributions here, and as much as you are obviously speaking on your own behalf, I think that as a general rule your last sentence might not hold true for everyone in every circumstance.

Kijanki, there have been many threads which speak to the trade-offs of using NF. Certainly, Ralph (Atmasphere) has written quite a bit about NF.

Just curious, does it matter how the NF is applied: local or global. For example, my amp uses a form of local feedback. I believe ARC describes it as "partial cathode following," which in English relates in someway to the topology between the output tubes and the output trannies.
