affordable long run IC

I'm running a six-meter run of Morrow Audio MA3 unbalanced interconnects in my SET audio system, and the sound is excellent. Mike's cables are very affordable in longer lengths, especially when you manage to catch one of his sales where he offers a discount on the length and termination options in addition to the base price of the cables.

If you can't catch the MA3 cables at a price that works for you, you might consider the Morrow MA2 interconnects, which I previously used in my SET system prior to Mike's introduction of his 3-series line of cables last year. The MA2 cables are excellent for the money, but the MA3s are noticeably better and worth the upcharge (IMO).

Cincy bob,

Are the MA3s shielded? Soon I will need a 3m single-ended run of ICs and I'm looking at the MA3s as a possibility.

Thanks.

I believe the Morrow MA3s are unshielded cables. However, I believe Mike makes a shielded cable as well, and it may be possible for him to install a shield around his MA3 design.

Based on previous discussions with Mike, I know he believes that shielding generally degrades the sound quality of a cable. I believe he uses a twist/geometry for the individual conductors comprising his unshielded cables to reject EMI/RFI. In my SET system where I am using a long (6-meter) pair of MA3 interconnects between the TVCs and 300B monoblocks, I have been lucky in that there is no noise whatsoever introduced by the use of unshielded cables throughout the system. (YMMV, I suppose.)

Thanks Cincy bob!
In what type of application is shielding necessary? I have read that shielding does degrade performance, but I'm afraid I may need it.

BTW -- NICE system!

Thanks, Musiclover.

I'm no expert on EMI/RFI. However, my general understanding is that the longer a run of unshielded interconnects gets the more likely it is you will pick up noise. At 3m, there is a good chance you would be able to get away with unshielded cables without introducing any problems. As I mentioned above, I am running a 6m pair of Morrow MA3s with absolutely no noise pickup.

My suggestion is that you call Mike Morrow to talk with him about his shielded and unshielded options and to get his recommendation for your application. You can always try Mike's cables at no risk for a 60-day audition and return them for a full refund if you encounter problems.
