Crutchfield Customer Review (What's this?)
I am using this because my onkyo receiver does not have pre-amp outs, but I want to power my new Polk RTi A7 speakers with a stand alone power amp (Crown XLS 1502). Works great, was easy to connect and the sound is clean! I can't tell that there is any added noise in the signal due to adding this device. I am happy with the purchase and would highly recommend if you want to run an external amplifier, but your receiver doesn't have pre amp outputs.
Pros: Small and affordable
