IC's between Power Amp and Pre Amp

I own and love Nordost Red Dawn. Whatever you decide on I strongly suggest you buy used, that way if you're not happy with your first choice you can resell it at your purchase price and try again, over and over until you're happy. Good luck!

Purist Audio Museaus works very well in my system,

I have had good luck with Z-squared via auctions on the 'gon and have really enjoyed them and still do

VH Audio Spectrum (copper). $400/pair direct with a 60 money back guarantee. I can't imagine you will return them.
Incredibly transparent and open.
In my system (Modwright SWL 9.0SE, Modwright Sig. Truth Platinum Sony 999ES, CJ MV60SE, and Aural Acoustics Model B) I found them to be better than Oritek X-2s and Nordost Quattro Fils.
I'll post a review in a week or so.

Transparent Music Link Plus current MM version.
