I have to agree that fixing the room’s A/C. Is the duct open all the way? Can you slightly restrict airflow around the house to increase it in your listening room. Most amps add so little heat relative to the overall temperature budget in the room... walls, floor, furniture... etc.
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?
