Speaker cable vs. interconnect cable length

That's what I suspected. So, in a case of an RCA IC, is it still a better idea to go long IC / shorter speaker cable?

Tonyptony...You will get all kinds of opinions on this. Mine is that if your preamp has output impedance of about 100 ohms or less (ss usually runs around 50 ohms) long interconnects should be no problem. For tube circuitry, where 600 ohms is not uncommon, I would keep the interconnects to less than about 8 ft.

Yes, I have a SS preamp, but I'd be looking at ICs on the order of 20' or so.

If it were me I would go with the 20 foot interconnects.

I agree with Eldartford, with SS it shouldn't be a problem. I have a high gain tube amp with an output impedence of 600 ohms. I use 25' IC's and can detect no loss of information when compared to 3' IC's. Just keep the IC's away from anything which might introduce noise, such as parallel power cords, transformers, etc.
