Music heard was same as that on DAC. XLR cables were hanging from the power amp and dac, but not connected together. Preamp was unplugged and in another room!
A Ghost in the System? Music Thru Speakers with Preamp Disconnected
I disconnected my preamp yesterday completely from my system in order to install some constrained layer damping tape. The DAC was on and receiving music, but the signal chain between the power amp and the dac was completely broken due to the preamp being removed. BUT: I could hear very low volume, but very clear, music playing thru the speakers! And no, I was not intoxicated. How is this possible? Cool stuff. Thanks.
