amp /eq rack, thermo control fans built into top shelf

Here is a link to my latest project. I wanted to provide cooling for my amp; primarily for the power tubes, the power trans and rectifier temp.

I'm bi-amping employing a miniDSP, the top speaker unit is a single driver audio nirvana (tapered side vented) covering ~220Hz up driven by my tube amp, the base unit is a horn unit I made being driven by my acurus 150. The fans are extremely quiet (sold by ac infinity).

I noticed the GRACE m902...that company makes very nice equipment...sturdy, well built and very well thought out products that are MORE than efficient.
I own the Grace m920...purchased on Massdrop

yea, I'm very happy with my 902, and understand the 920 has an improved dac
