Class D for a Tube Lover


First, I'm sure this has been asked many times but searching the subject wasn't too helpful to me.

So apologies in advance.

I enjoy tubed electronics and class A amps, which tend to be a bit warm.  My current Cary 805s warm my small (12x16) music room even in the cool/cold of winter.  I've got other amps that don't produce much heat, but am looking for something that produces no heat.  Living in a home with no central AC the room gets uncomfortably hot during the summer months.

So...I'd like to try some Class D amps.  Stereo or mono is just fine.  And my speakers aren't difficult to drive so I don't need a thousand watts.  But if that thousand watt amp sounds great, I'm not adverse to that, either.

I'd like to keep the price under 2k used.  

Please help.

Thanks.

I own a Pass Labs Aleph 30 (30 watts, Class A) that is exceptional. And, it’s also an exceptional space heater. On a whim I recently purchased a PS Audio Stellar S300 amplifier for the sole purpose of trying Class D amplification. After about 100 hours of use I can say that the amplifier generates little to no heat and so far I’m feeling like I gave up little from a performance perspective. Insert all of the audio descriptors here…

In addition, not that it is necessarily a priority (for you), but PS Audio has a generous trade-in program and the direct purchase process was excellent. Zero affiliation, just passing on a very positive experience.


Class D sounds good but is good good enough? If your a critical listener most of what is out there is not going to make you happy. Paul of PS Audio has several videos about class D and he said more than once that he likes the sound of his AB amps over his class D amps, use this to give you an idea of what you might experience.

I have heard class D that is outstanding but it is not in your budget.

My best advice is do not buy until you hear.
I use both. Valves in the cooler months with class ds doing bass duty. Then in the summer I change to a LOT cooler running class ds for the monitors. I use a Cary V12r and Mac C2500 for a front end with tone control.. With tone control, you'll get what you want, without it.. I'd doubt it..

I use Nord NC500 with Sparco 2590s OpAmps and rev d buffers.
Purifi is all the rage, To tell the truth, My NC500 are pretty tough to beat..
I'd like to give Nords ET400A a run with Nord buffers though.. The 9 NC500 modules I have, I've NEVER had a problem.. Sound wise.. pretty friggin good, for the 4 months a year I use them.. BUT they are not valve amps.. They don't sound like valve amps either..

Lot of Mac and a few Cary's in my gear chain..
