heimdall Posted June 4, 2013 Posted June 4, 2013 Looking at building some interconnects but I can't find anywhere that stocks belden 89259 coaxial? Any suggestions where I can find some? Or an alternative that would be as good?
Zaphod Beeblebrox Posted June 4, 2013 Posted June 4, 2013 Looking at building some interconnects but I can't find anywhere that stocks belden 89259 coaxial?Any suggestions where I can find some? Or an alternative that would be as good? 89259 is 75 Ohm cable, designed for RF and video applications. It will certainly work well for audio. I don't stock any. I do, however, have 300 Metres of Belden 8761 in stock. Very high quality audio cable. 5 Bucks per Metre. 1
Decky Posted June 4, 2013 Posted June 4, 2013 (edited) 89259 is not imported in AUS and RS/Farnell would probably charge you $300/m. However you can get it from here http://www.rawcable.com/cable/index.htm enjoy Edited June 4, 2013 by Decky 1
heimdall Posted June 5, 2013 Author Posted June 5, 2013 Thanks for the reply's guys, rs does have it but at 610 for a 30m roll I might take zaph up on his offer
Nada Posted June 5, 2013 Posted June 5, 2013 Looking at building some interconnects but I can't find anywhere that stocks belden 89259 coaxial? why belden 89259 ?
andyr Posted June 5, 2013 Posted June 5, 2013 Came as a recommendation from a friend. I only use solid-core wire in the signal path, in my system - so I would not use either 89259 or 8761. If you want to DIY some good-sounding speaker cable, you might care to read this article, written by Lewis Muratori (now, sadly, passed on) and added to by me : http://www.aksaonline.com/discussion/discussion_papers_connect.html Regards, Andy 1
Decky Posted June 5, 2013 Posted June 5, 2013 why belden 89259 ? Mainly because of the low capacitance. Also there was a lot of publicity made around this cable by the DIY community. I would agree with Andy - I personally do not see anything special in 89592 but it is a better and completely different cable than 8761. I would actually suggest LC-1 cable form the same place http://www.rawcable.com/cable/LC1.htm That is a beautifully designed coax for audio.

For interconnects, I personally prefer Belden 3079A twinax - because both signal & earth are solid-core. The braided shield you just connect to the RCA plug at the Source end - it's not part of the signal chain - or (more work! ) you do what I do - twist, say, a 100mm length of the shield into a wire having a spade connector on the end, which you then connect to one component's case earth terminal (which is connected to the mains earth, so earthing the case), to avoid the RFI which impacts the shield from polluting signal earth).

Regards, Andy I agree - Andy sold me the idea about 3079A - one of the best cables I have seen and heard. Not a coax but that is even better in my opinion - I am not a fan of asymmetric signal paths. You can get it from http://www.madisontech.com.au/brand/belden Edited June 5, 2013 by Decky 1
Decky Posted June 5, 2013 Posted June 5, 2013 Yep - just send them a mail. Most of the cables I ordered from them are sold per cut meter and postage is very reasonable. 1
Decky Posted June 6, 2013 Posted June 6, 2013 What is amazing about that cable is Nom. Mutual Capacitance @ 1 KHz 27.888 pF/m That is the only commercial cable that came even close to the capacitance of my silver in cotton DIY twisted pair of 20 pF/m 1
