Query: excellent for my application

I use this to push my outdoor and upstairs speakers that have a higher (needs more power) sensitivity than my living room and dining room speakers. I take the tape out feed from my main receiver and plug it into the inputs of the Amp 100. The quality is amazing for the price; this thing is solid! I don't know if it is audiophile sound but I am not using it for that purpose and not pushing audiophile quality speakers with it. The product is absolutely perfect for what I am using it for. I highly recommend it to augment a whole house music system.
