Thanks for all your input. In fact my tuner is out being repaired which is how I notice the difference in sound. I think it's a matter of RF which is leaking from tuner input into the rest of the preamp. I think it's not resolvable unless I actually unplug the tuner's interconnects from the preamp.I would leave the tuner plugged into ac when not in use but left off and unplugged from preamp. I'm hoping this would be my solution. Any thoughts or advice?
Does anyone notice a reduction in sound quality when a tuner is part of ther audio chain?
I notice that when my tuner is taken out of my audio rack/chain that the sound quality from my system is significantly better. I like the sound of my tuner but when disconnecting it I find the cd player has a much quieter overall sound. If my tuner is attached but turned off I still find the sound quality less than if the tuner is disconnected completely. Is my best option to simply disconnect the interconnects from the tuner to the preamp when not using the tuner? Would a better preamp resolve this issue or is it a matter of RF leakage that would happen with any preamp?
