Bopper Canary Audio has very well made and good sounding products. I don’t think you can go wrong with the M350 amps. I have quite a few amps but recently I got a deal on a Canary Audio M90 that I enjoy much more than the First Watt Sit 3 that all the critics loved. The critics aren’t wrong the Sit 3 is a very nice amp but I like the tube sound of the Canary better. I have considered moving up for more wattage as I need a little more headroom for some music.
