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.

Thanks for the time & replies.

Encouraging news on the XA25\AHB2 direct comparison. Also great to get some alternative amplifier options to pull up and review.

The room AC isn't a drastic or large comfort issue. It's just noticeable to have the heat from the amp rising from the rack as the cool air comes in from the ceiling. 

I'm sure there's a small itch to try some new gear, and I'm still evaluating the purchase heavily. The Pass amp & pre are really delivering. It's nice to test & learn, and there always seems to be some lost time and cash involved when things don't meet expectations.

Appreciative for the continued comments. I've pulled up multiple suggested items and reviewed.I would have a lot of fun ordering $50k of hardware to listen to and test - I would spend the time without complaints and keep myself busy for a long while if it were possible.The AGD line would be entertaining I'm sure.

The decision I've made that will help make sure I'm not just 'buying & trying' in a cyclical routine is that I need to seek out and hear some of these options before I make the purchase. Class A is good, sound is great. Runs warm...I'll live with that for now.

I had a Firstwatt J2 prior to the XA25 - sound was very similar. Maybe many of the Nelson Pass amps are similar... I've only heard these two. Bass control was a stand out improvement with the Pass over the Firstwatt though. I never had an issue with output or SPL - I think the Pass has more headroom but I don't push things that hard for it to matter.
