Digital cable optimal length?

YES- 75 ohm BNC and RCA connectors most certainly DO exist: Refer to the site URL that I posted previouly in this thread.

I owned both .5 and 1m Kimber Orchids for use between my CAL Delta and either Sigma or Alpha DAC(back when). The .5m was consistantly terrible(in a number of audible ways), compared to the 1m(which was wonderful). Rat Shack cables(like everything else from them) would be a total waste of money. These are inexpensive, but highly regarded, by everyone that has auditioned them: (http://www.cs1.net/products/canare/LV-77S_digital_audio.htm) They won't break the bank, at any length you choose, either. NO- I've no "connection" with the company. =8^)

Tobias- Read the Jan 2,1997 entry in it's entirety: (http://www.soundstage.com/feedback/resp01.htm) You would think that the people marketing, or the thousands that have purchased Canare 75ohm RCAs over the years, would have noticed if they did not deliver a true 75 ohms by now. (http://www.markertek.com/SearchProduct.asp?item=RCAP%2DC3A&off=6&sort=prod&skuonly=0&search=rca&pagesize=20) "Beyond a shadow of a doubt"? Buy a pair(they'll cost you under $10), attach them to some 75 ohm cable, and use an ohmeter on the assembly. I'm certain thousands of others have tested the RP-C4 RCAs, and LV-61S cables, to remove their doubts too. (http://www.avbestbuy.com/webpage/sayaboutcanare.htm) It seems some companies are buying Canare products, disguising/relabeling them, and selling them as their own(interesting)! =8^)
