I am getting ready to get a pair of SDA2s and I have a Hafler DH500 amp.
The amp is currently being run from the pre-amp output of an older Denon
receiver through some Bose bookshelf speakers and works superb.
So here is my problem:I was planning on using a Harmon Kardon 2.0 signature series pre-amp. When I hook it up to the Hafler I get a LOUD hum/buzz.
The pre-amp is designed for a surround system but I was planning on
using it to just power my SDA2s. Should I be able to use the "Front" output from my HK pre-amp to my DH500 and get full sound out of my SDA2s or does such a pre-amp have to have all outputs(sub,center,surround)connected to a surround amp or several amps? Any thoughts on the hum. It happens with or
without any source input. It happens no matter which output I use.
Thanks for any thoughts,CJ.
