I have a fairly high end system adn I find myself moving my equipment in my room reasons of isolating the turntable and aesthetics. I now need a 17 meter interconnect. My preamp is currently a Joule which has a reasonable amount of gain. I am running single ended. I do not want to spend more than $1000 and I have no DIY skill (or inclination). Any recommendations? Possibly audioquest coral form HCM in California for $465? Is there anything else. My other IC's are Cardas Golden Reference and my speaker wire in TG Audio.

I think you've gotta do what Jim recommended ...:a) ask the cable mfrs what capacitance their IC has, per m. 150pf per m is fairly low but not unachievable ... that calculates to 2,500pF.
A good preamp should be able to cope with this but ...
b) you need to ask Joule what cable capacitance it can cope with.
There is also the issue that 17m of IC MUST do something bad to your sound. 17m of speaker cable is likely to do something even worse but is there any way you can shorten this length for ICs?
Regards,
Which Joule preamp do you have? The reason I ask is that 17 meters of IC is likely to have a significant amount of capacitance which could potentially roll off the high frequencies. A typical cable will have 100 to 250 pf/meter, which calculates to 1700 to 4250 pf total. That's quite a lot of capacitance, requiring a good amount of current drive and your preamp may or may not be up to it. The standard IHF "stress" load for testing preamps is only 1000 pf. If you want to get that long an interconnect you need to look for a low capacitance cable to minimize problems - unfortunately many cable manufacturers do not publish this information so you may need to ask them directly.
Joule LAP 150 MK II. (newest version).
Well, that has a nice low output impedance according to the Joule website, so there shouldn't be a problem with high frequency rolloff, but there isn't anything on the website about how much current it can provide. Not unusual by the way, I don't know of any manufacturer that specifies that, or any standard way of measuring it. Most preamps aren't designed to drive a high capacitance load. You may want to consider shorter interconnects and longer speaker cables.
