interconnect help

...to the author's last question the simple answer is BASS especially if you have an analogue source.

There are inexpencive professional grade (RCA or XLR) cables that you can successfully use on any audiofile system and with huge lengths. Try to get Canare japanese pro interconnects that are being widely used during recording in the studios. They're available in SamAsh music stores. At least you can buy them and try them for a measurable price.

...and I wish to continue with capacitance issue: the pro interconnects are basically designed to work with pro tube gear as well.

...I think that is simple to measure for Audioengr! :^)

As to Canare the manufacturers simply state that their product is designed to work with tube gear and have long runs upto 25...30 feet.
I've got a friend who's using the shortest available Canare cables ~2m with passive preamp very successfull.

The sonic performance is compatible with AudioQuest DiamondBlack or even better at fourth or third fraction of its price. They're considered to be of the higher priced and high quality professional grade interconnects.

Moreover you gotta stay tuned for more reviews from more users!
