Worth upgrading from Morrow MA4's?

Zd542, there is not always the opportunity to test cables. Stealth Indra were not lent out by the Cable Company nor were they on loan by the manufacturer. I made another mistake: I bought Purist Dominus interconnects for my Atmasphere MA 2 and MP-1, only to be told by Ralph that he recommends Mogami Neglex (We're talking $5K vs $200). Guess what ? The Mogamis sounded as good. But I didnt know this before. So I am not crying victimization here -0 you choose your words harshly - I am claiming ignorance, but ignorance that is retrospective. I am trying to help Rrolack making similar very, very expensive blunders! And I am doing that by asking him to try cheaper alternatives first. Is that clearer to you? There is nothing more contentious than "cable costs" and I will stop there.

My answer is an emphatic No. I have used Morrow 4s - they are very good but so are others costing half and double. I offer to send you a cable ( on loan) costing half, and if you can have someone change your cables blind, and you can identify significant difference, then you'll have some sort of answer. I have become a cynic of expensive cables ever since spending a hugely embarrassing amount in 2004 on Stealth super- hyped cables only to trade them for cables one tenth the price a year later with no regrets. I hope you get my point. The cheaper cables like clear day, signal, art audio, Mogami neglex all prove my point.
I am neither a dealer nor have any financial interest in any audio component but read so much hype and garbage about cables that I thought I'd save you some $$$!:)

As a post script, Zd542, how do you claim to "know you're making the right choice always" if you cant always test cables?
Only buy from The Cable Company? Furthermore, I bought the cables from a friend and am certainly not blaming him nor anyone else. I acknowledge ignorance totally, not blaming anyone. Re-read my post.

Al is correct. A pair of 15 ft was about $100 a pair. My apologies. Furthermore, if Ralph's theory, proven in my case, that if the amp and preamp match perfectly, the cable expense is irrelevant. So even more evidence that this is all a crap shoot in most instances, supporting my thesis of trying cheaper first, which was all I was trying to say!

"simple. I know better" seems to be an apt credo for you, Zd. Patronizing and self righteous posts ruffle my feathers more than subjective posts. But that's just me. Cheers!
