I've got a Sony STR-SE391 receiver that came out of an old HTIAB system (
Specs 435k .pdf file) that I'm using for part of my whole-house audio system. It's powering 2x NHT Absolute Zero's on the A channel and 2x NHT Classic Two's on the B channel. I'm not blasting the music and it seems to be working reasonably well. Is there any reason for me to be replacing this unit with something like a Sherwood RX-4109? If so, what would I be getting out of it?
The unit does seem like a space heater, but I am turning it off when it's not in use.
Relevant specs from the PDF:
8 ohms at 40 Hz - 20 kHz
less than 0.5% total
100 W + 100 W
