The Fosi Audio BT20A Max seems to run warm. Even idling with no music it is warm. Really wish it had a standby mode.

I'm looking for a small shelf for my BT20A Max, my Wiim Pro Plus, and my Fosi Audio Merak CD player. I've seen a few online, but they're pretty tight for this amp. The Max is 45 mm thick, and add a couple of millimeters for the little rubber feet. It is pretty close to 49 mm. I want the CD player on the top shelf. So I need a shelf that has some clearance for the amp. Fosi sells one. It's a bit more expensive than I want to spend. Are there any other small 3 shelf options that you would recommend? Thanks.

I have the Fosi BT20A Max with the "regular" 48V 5A power supply. I am using this to power a pair of PSB Image 4T speakers. Seems to do a decent job in my livingroom, just thinking I want a bit more or if it.

Would changing to the 48V 10A power supply have any effect?

I suspect no.

Thanks for the assistance!!!

I just ordered the Fosi BT20A Max with the 48v 5a power supply. I have a pair of PSB Image 4T speakers that I plan to use. Can I use my Sony 5 disc changer and plug it into the RCA inputs on the amp or do I need a preamp? Sorry if this is a stupid question.
