First foray into Class A amp -- recommendations


Thinking of checking out a Class A(or quasi) amp just to see if the sound is really better than a nice Class A/B amp. I want to buy a used amp and my budget is $2500-3000. My current class A/B amp is a McCormack DNA-1 Deluxe, rev. A.

I've been looking at a lot of amps here on A'gon and what I have come up with so far is the Krell KSA-200S, which, from what I read in reviews, operates largely in Class A into 8 ohm loads up to 200 wpc.

Considering that my McCormack is a pretty decent amp, do you expect that the Krell would offer a significant upgrade in my priority areas of bass slam and control, mid range transparency, and natural high frequencies? I also welcome any other suggestions or ideas. Thanks!

response to Jdoris about his comment that the Pass int-30a's power isn't higher than 30 watts:

It switches to AB above 30 watts and clips at 130 watts at 8ohm, 190 watts 4 ohm. So it's not about "effective" watts, but about actual power you can measure. The xa30 and int 30 amps are actually 130watt @8ohm, 190 watt @ 4ohm amps. The first 30 watts are class A.
Mtrot, if you go and audition a krell 400cx or 700cx, they will clearly out perform the pass labs amp you listened to, espeacially with high quality cables, my depth of the sound stage to me is endless,voices and instuments are incredible!

Why would he want one of those problematic amps? I've heard they have microprocessor boards controlling the bias, and the boards are always screwing up so bad that even their own Krell technicians can't fix them.
Keep it simple!! Besides, I don't think those amps will be in his $2K-$3K price range.

Go ahead AL, get some practice using the markup tags on this reply. ;^)

See how easy that is??? LOL!!
Fair enough. Skkotb.

But I stand by my comment: If you have moderate or lower efficiency speakers, there's considerable risk the Pass 30s won't be showing their best. (Which, I suppose, is part of why Pass sells many more powerful, and expensive! ;), amps.

If the OP is after "Class A" sound, his issue may not be how the 30s measure in A/B.

Of course, YMMV.
