I have found myself at a crossroads trying to figure out my next upgrade.
^Sounds^ like the opening to, "And I sold my soul".
Right now I believe my DAC is my weakest link (by a long shot)
How would you go from belief to proof, or some reasoning that could convince others?
The whole "System" talk implies that things are multiplied together.
But it is probably more like a chain analogy,
If there is no fuse in the amp, you have a bit of a problem making sound.
And a $1000 fuse is not going to make a $5 speaker sound 1000x better than a $1 fuse.
That changing cords/fuses/interconnects is mostly just "blind making work". If the Phono amp is not good, just get a good one... putting a "magic tube" in as better phono amp, will likely be more magical than putting it into a phono amp that is flawed (if your’s even is... I really dunno.)
