I can agree with that. But, I ask you this. What about your preamp(s). Your amp(s)? Are they tube or IC? Your speakers? Do they have built-in cross-overs or do they accept all input provided to them?
Specifically,
What kind of phone does this? If it is not too much trouble, please provide a make and model.
EDIT: I also assume you are not running copper wire, but optical. If you don’t mind again, what do you run for your HiFi system? I run a Yamaha pre-amp and amp, along side a Pioneer Elite stable platter CD player. I run this through Polk Audio towers and sub. I showed you mine, and am willing to share pictures with me in the shot as proof. Show me yours?
EDIT 2: You may reply your input is not CD, that is ok. This only means I ask for the transfer method between source and, well, what is sent to your ears.
