The v2.1 runs cooler because it has ventilation holes!

Admittedly, it is on top of my power amp, but I can't imagine it making that much of a difference (especially considering that it actually runs warmer than the power amp).

It should run just as hot as a pre amp as it does as a headphone amp.

Hm, maybe I'll try moving the m-stage. It definitely gets much warmer when I use it as a preamp.

Heat does rise, but saying that holes in the side of the enclosure do nothing is a bit ridiculous.

The guy saying it did say that he didnt understand whythe holes were not on top instead of on sides..as that would help better..but as i said..these are not my words.. biggrin.gif

May be a strange question, but I just opened this to toss around some opamps. Has anyone played with the voltage pots on these? That is a SUPER fun tweak to play with.

Unfortunatelly I don't have the schematics. What exactly do you believe those pots do?

They should change the voltage in circuit. Wayyy back when I had a Roc and Phoenix from Audio-gd changing the voltage drastically afftected the sound overall.
