Who uses long interconnect like in dealers?

I too am looking into this for my set-up. But I'm plagued by the thought of effectivly having this HUGE antenna between my control unit and amp. Yikes! Since I cannot go balanced with my equipment choices, won't this degrade sonic quality? Or are single ended cables shielded enough to stop the pick up?

Best,

Mprime, You do have to be careful with cable selection to avoid RFI but unless you have unusual problem in your area good shielded cable should work fine. I would recommend that you audition the cable first. The only problem I have had is when I ran the cables parallel to power cords or near large power supplies - and thats easy to correct. I've never experienced RFI thru the cables.

I use 6 meters of Randall Research TX, which I recently
convert to balanced/XLR.

You rarely see long interconnects because of the wide spread use of equipment racks. I can't believe people continue to put these racks between their speakers.

Kana, how would you describe the sonic differences between the balanced run against the unbalanced?

Mprime- the noise floor was lowered, and output from the preamp increased,which lowered volume settings. Both of which improved low level listening pleasure.

Since the cables had been used for 15 years, there wasn't
any change in the basic sound qualities of the cables.

A nice improvement for $20. in parts and a little bit of
labor.

I never had an RF problem in my room with the cables in SE
config, but I think that's more a function of good cable and
equipment design than the length of the cables.

Suggest you borrow a long IC run, and see if it improve the sound of your system. I've run my audio systems with
long ICs and short speaker cables for the last 20 years.
