There can only be one!

I have a $5 BT board that I tried with a tpa 7498 amp but too much BT noise. It is sharing the same power brick as amp. It sounds kind of like the old dialup modem noise! lol.
I just splurged for a SMSL SA18 amp at $144. It is more than I wanted to spend but its for the granddaughter's bedroom/dorm room-eventually. Seams to get good reviews, lots of input choices, decent power, etc.
