What would one replace Nordost Valhalla with??

Try the Kimber Select 3035's.

First a disclaimer: I'm highly biased towards MIT, both as a reseller and as a former employee.

In the last two years, many of my friends/clients have done direct comparisons between the top Nordost cables and the MIT Oracle Series. In every case where there was a purchase decision to be made, the the end-user went for the Oracle. Part of the reason for this is because MIT provides for impedance-matching of interconnects and also for amplifier-type-matching of speaker cables.
Best of luck,
Joe

There is another thread called "former Valhalla users" you should refer to.

i already got all valhalla cables(ic,speaker,digital).
for me ,in my systems, jena labs,kharma enigma,synergistics designer squared reference were better than valhalla,also some of my friend prefered mit or siltech over valhalla.

Pure Note Epsilon Reference. The have much more body in my system.
