Thank you for the prompt replies.
The Lepai is what I own (about $20-24 on amazon), I've used the supplied power supply, a laptop supply and a monitor brick, same result.
I suspect my speaker load is not ideal for the Lepai amp. Also I am hard of hearing so run more volume than most.
Sure-HiFi offers what appear to be "big brothers" to the Lepai amp, without a case.
This one interests me but I think the 36 volt switching amp they sell would "pair" well with it. Just wondering if at their prices they are likely to be junk?
Actual components(yes look at shipping charges)
It is supposed to run on 12-36 volts
Quality of these kind of purchases vary a lot, so any input would be helpful.
