Reasonable but not outragious interconnects

I have quickly browsed through some of the responses provided to OP. I remember seeing someone suggesting to pay attention to "ends" (aka terminations at each end of the cable), I completely agree with that and couldn’t emphasis more on the importance of quality terminations. I tried DIY myself many times for the cables (such as Mogami, Canare etc) with some success. I recently got my cables from Benchmarkmedia.com, and I immediately felt the difference in sound staging, channel balance, tonality along with some gain. I think benchmark use Canare cables are very reasonably priced. I have compared their cable with AQ (XLR) and didn't find any difference. So my advice would be to use reasonable priced cables with best possible terminations. All the best.

If you are using balanced connections, the screen should be lifted at the destination end.
If you use single end termination at the destination, it forms low-pass filters for common-mode noise resulting in degraded CMRR at higher frequencies.

Unbalanced cables using more than 1 center conductor, i.e. twin screen or star-quad should also have the screen lifted at the destination end.

try Rega RCA interconnects. 1m for $100. Rega is known for it’s performance/value ratio

I see one other comment for SVS. I have been using these for about 3 months and really like them.
