Class A\B or D for summer months (vs Class A)


I have a Pass XA25 with a XP20 pre-amp with Forte iV speakers.I bounce back & forth between streaming local content & vinyl. Noise floor is low, sound quality is good through the volume range - Classic rock, hard rock, blues rock... Typical late 70's through 90's mainstream bangers.

Last summer I did notice the XA25 amp and my central air were battling it out a little in the listening room. The amp had no issues and runs warm regardless of season. I guess I notice it more when I'm looking to stay cool vs stay warm.

 

I have a Benchmark LA4 preamp that I used prior to the Pass XP20. I'm sure there's good synergy between the Benchmark LA4 and Benchmark AHB2 amp so the AHB2 has been on my 'investigate further' list.

I'm a little worried that it might be too thin or sterile vs the XP25. The AHB2 would certainly help reduce the heat.

Anyone been down a similar path with thoughts to share?

I was shooting for the $3000 price range -

Used is fine, sometimes just tough to find the exact item you may be searching for.

I have directly compared the XA25 to the AHB2 and they were quite similar in sound. The AHB2 idles at 20 watts and doesn't even get warm.

This is a case where you might like a Coda A/B which tend to run very cool, but are still linear amps.

I'm not against Class D at all, I just can't imagine going from Pass with it's own signature to any Class D amp and being thrilled.  I'll be interested in reading how your listening goes.

The Atmasphere GaN amp was designed by a foremost tube amp designer and can be found used on hifishark in your price range if you’re patient.  Best of luck. 

You shouldn’t be restricted by your imbalanced AC unit. Run any amp you want in perfect comfort.

My listening room was furthest from the AC unit and couldn’t keep cool. Installed a mini split AC unit. Runs perfectly quiet.(no, really, it’s silent) I noticed that they use the same units in PS Audio listening rooms also. I Use it like a light swtich.

You can see the mini split unit on the right wall up near the ceiling over pauls head.
