The all-time( for me anyway) best buy for copper speaker cables is the new Flexygy 6 cables from River Cable. I have auditioned many speaker cables from DIY to popular name brands and none have had the musicality,emotional involvement,transparency and naturalness that these new Flexygy 6 cables have. I would put them up against anything up to $1000.00/pr. I just bought a 4 meter pair for my 2nd system for $254.00, shipped free. I am so mesmerised with their incredible sound that I might buy another pair for my main system. My main system is currently alternating between the MIT Oracle V3( $5000.00/pr.list) and the new Acoustic Zen Double Barrel( $1,850. list). Yes,the Flexygy 6 cables are that good, at just a fraction of the cost. Plus they have a 30 day money-back guarantee. Stereophile just claimed that their new Digital interconnect is the best they have ever tried. To say the least, I am very impressed with these River cables. And they also come with their own "Birth Certificates" which have a statement saying, " Congratulations, you have a new River cable."But cuteness aside, on this certificate is a rise time square wave that was put through each cable and the square wave looks better than most, if not all, speakers can produce.I feel that this River Cable company is going to be very popular. Oh, and regarding MAS interconnects, the best one is the Black( cheaper than the Grey) and then only from your Cdp to pre. Phasecorrect, if you could post your virtual system, I can recommend a good ic for pre to amp. Website for River Cable is www.rivercable.com. Just for the record, to all you sceptics, I am not a shill or dealer for River Cable.I simply took a chance and mail-ordered a pair and I, myself was very sceptical initially, but after initial listening( they sound great cold, out of the box, with no burn-in) I was quite astonished. I rarely go through "jaw-dropping" experiences, but these Flexygy 6 cables did it for me.
