I auditioned Raidho D3's with Ansuz D-TC speaker cables, cables were impressive. Due to the high cost of the D-TC's I went with Ansuz Diamond, I have a good sound but would like to upgrade at some stage.
Upgrading the power cord on my Audio Research GSPre to Ansuz Ceramic is very audible. I am new to this HiFi world and was skeptical at first, I played safe with Ceramic, now that I'm comfortable, my future power upgrades will be Diamond. (Longer cable length recommended).
I have Transparent Ultra cables on my first system but went with Ansuz, as Raidho demo their higher end speakers with them. Transparent higher end cables are very expensive also, (Reference/ Opus).
If the opportunity arises, have a listen to D-TC speaker cables.
