Pure Class-A Amp under $2000 (USED)

If you want pure class A and high power you need a push/pull amp. While very rich class A no push/pull amp stays class A into all impedances at high power. Only a single ended amp(which can only be class A due to circuit topology) is ALWAYS class A and they are almost all low power.

Then again an amp that is say class A up to 30 watts is almost never out of class A and if it is it's for mili seconds mainly> For instance the 30 watt calss A Pass amps are 30 watts class A to 30 watts but then become class B up to around 75 watts(why he calls them 30 watt class A amps. If I recall correctly(someone may know better) if a push pull amp is class A at 8 ohms at a given power it stays class A only at lower power into lower impedances.

SUGDEN

If you are looking for a pure Class A (not a class A rated) power amplifier then PM me and I can send you a LUX kit pure class A amplifier for you to hear.

@darkknight8586 I believe Krell KSA 150 and 250 operate in Class A and deliver plenty of power. There are some other Krell models such as sustained plateau biased models also operate in pure Class A. There is one KSA 150 available for $2,500 if you are interested. KSA 150 burn 300W when at idle! Class A efficiency is very low around 10-15% tops. For this reason, I purchased little brother in this series KST 100, but Class AB biased. Imaging, depth, spacing around instruments are outstanding.

It seems that Sugden is quite favourable by many users, and they look very nice

@pwerahera how do you feel about the sound of Krell? I heard they have a very forceful bass.
