Josh, it never stops does it? The tweaking i mean. ha ha.
well from my experience changing out interconnets can also help tame or add detail to the final sound. What type of interconnects are you using?
I tried pure silver IC's before.. and while they are very detailed.. it was to much to bear.. it was to much of a good thing. So after about two months, I had to replace them with what i am using now.. Silver over copper wire... retained the detail, but smoothed out the high end treble. It is the best of both world.
Raymond Cables these are what i use. I found this guy local to me that builds these. He's very knowledgeable about cable design and what different types of wires add or detract from the sound.
