Removed SP1.7 from system for test

[Ghost rider]

I tried posting in the McIntosh section but I got no interest. For some time I have out grown the SP1.7. I have upgraded my 2 channel system with a McIntosh C2500 tube preamp. I also use an Oppo bdp 105D for all my movies and much of my music including DSD.

All I have used the 1.7 for is the 5.1 analog input and to turn on the HT bypass in the C2500. It seems to me that it is a big waste of electricity. I made up a switch box to turn on the HT mode in the C2500 and ran the channels straight to the power amps rebalanced all the channels. Seems to work fine, a little different possibly better. A little brighter and more detail.

On a positive note the setup eliminated a ground loop I have had for years and have filtered out.
