Give The Cable Company a call and demo some new cable technology. There is so much new stuff out there that smokes older designs. I suggest you try Synergistic Research's new Tesla series cables. But The Cable Company will be able to make many other good suggestions as well.
what is a right IC for my current setup
I am using a Techincs A-10 as my CD player, goes directly to my Krell pwr-amp, I use an old Cardas between the pwr-amp and the B&W 801. ( previously I was using an Audible Illusion L1 as the preamp). I am thinking of upgrading my IC between the DVD player and the pwr-amp. Would a Cardas Neutral reference or a Audience AU-24 a good match. I am thinking of either changind the DVD player to a SACD player.
