Good amp, but quality is questionable
The first amp they sent me had a faulty TRS jack. The male TRS would not go in all the way. When my replacement arrived, I noticed someone from the factory did not tighten the bolt on the bottom of the unit that holds the power amp in the unit all the way, and it was shaking around inside. I then plugged it in, and the unit itself had a annoying electrical hum. So I called for another replacement. This amp had a good TRS jack, was dead silent, but the binding posts were a bit sloppy. For some reason, the male binding post bolts that you use to tighten your speaker wires are not a consistent diameter. So I had to take them off my second replacement amp and use them on this one. Really Samson?! Really?!?! You forget to tighten a bolt for the power amp and your other binding post bolts are inconsistent? Amazing. We all know this is mass produced junk, but we have very few other options. On the positive side, this amp has no annoying loud cooling fans (like the ART SLA series) and they are dead silent. You can't even tell your speakers are on unless you jam your ear into the tweeter. And I am happy with the overall sound. Only thing I can do now is hope it doesn't fail in the near future! And last but not least, thank you to all at Sweetwater for the smooth transactions for my replacements. You cannot beat the customer service of Sweetwater. I rate this amp 3.5 stars and the customer service department 5!!
