Monos sound better hot??

[Louie3]

I have the fan kit for the V3 monos...obviously it could be my imagination, but the amps seem to sound better hot than with the fans.

I had the same experience today. The V3 Monos stay cool with the fans. However, the sound seems to be cooler and weaker, especially in the mids. It really seems as if the V3 Monos need the heat...

Do the fans share the amp's power supply?

No...they have their own five-volt usb power supply.

So without the fans, do the amps sound weak until they warm up?

If it was true that the 3255-chip operates better hot, should I place my Fosi BT30D Pro in the oven at 60°C to expect better sound? It is never warmer than my V3 Monos with a fan sandwiched between them, about 28°C. My Monos get about 60°C hot without the fan, even when idling.

One of my monos broke down after 2 months of intensive use without cooling. Fosi sent me a replacement board and I ordered a set of fans. I only use one though.

I have equipped my V3 Mono with 2 SS3602s each. This means that they are now significantly warmer. So I use one fan for both. They are together so that I place it between the monos. You can adjust the speed of the fans. So it works. Basically, every amplifier needs its own operating temperature. In summer temperatures or if you listen to loud music for a long time, this is better. I also use 2 48V/10A power supplies. However, I have switched to the GAN power supplies from Nobsound. In terms of sound, this makes a bit more of a difference in terms of dynamics. And this is TÜV/GS tested. In Germany, this is a sign of the best quality and safety.
