I have got a Parasound HCA-2205 power amp.
It is a cracking amp. I used to own a Denon AVC10SE (the one below the origional A1SE).
I thought that sounded good, until i sold it & purchased the Parasound. The difference in my opinion is quite clear.
It is built like a truck, has good quality connections, has 220W X5
onboard, and i believe has no inbuilt cooling fan.
As long as you give it a bit of room to stop heat building up to high, it's fine. It also has front & back grab handles (Thank god!)
although one of the back grab handles is a little too close to the speaker binding posts. They recommend turning each channel up to the 'THX' mark on the dials & let your processor do the talking.
Strange that they didn't put in little detents on the separate channel levels??
I haven't got it fully setup yet due to some decorating, but i can say it is a great performer.
Even with your A1SE, you'll notice the difference. I'm sure you will.
Get a good power chord & Bob's your aunt's sister.
The Denon has fine surround decoding, but the Parasound amplification is superior to the Denon amplification.
