There are more products out there now than ever before. It's a daunting task to weed thru it all. I say something's good, someone else recommends another, and so on. Without listening, who knows? I might be deaf, the others crazy.
I do know you've got a great analog system going. The P75- in phono enhanced mode- coupled with the 20L is a combo that never ever fails, unless of course it's on a VPI or Clearaudio or crappier than crap Projects. Like taking a Rolex mud wrestling...
I do like Rob's recommendation of that beloved Auditorium A23. Most sublime in your setup. He has great taste- far better than mine. On the cheaper end of things, I've been hearing nothing but raves about the very inexpensive CablePro Reality cables, out of Dallas. I'll find out soon enough.
There's also the AudioQuest line, which are making some fine sounding cables at all price points. I'd written them off, yet now have seen the light. Kimber bores. Sounds off to me anymore.
And someone played some Blue Jean for me once, I almost puked, it was awful.
So I second Rob again, Mogami with Eichman bullets is wonderful for little money. Also DNM, who use those beloved Eichmanns as well.
Listen first if you can. You'll have a great great rig when you're done. Be sure to keep your stylus clean.
