Worth upgrading from Morrow MA4's?

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 $$$!:)

If you can spring for them, there are some Darwin Ascension Plus B-Stock on sale here. Having them in my system and broken in, I'll go as far as to say I would have paid full price for them and not regretted it in the least (I blow the difference on wine every two weeks).

All the best,
Nonoise

Springbok10, I must admit that the Clear Day Double Shotguns you sold me this week sound great :) If Clear Day made ICs, I'd want to try them.

Almarg, the ICs I'm running are all 1 meter in length, so pretty short.

Rrolack - I own Clear Day double shot gun speaker cables as well and think they
are great. But fyi...Paul Laudati/Clear Day does sell ICs...search for Clear Day or
VonWaffen either here on A'gon or on the Audio Asylum Marketplace. There are
some on AA Trader now.

I don't see how you can prove something that's subjective. More importantly, though, your post touches on a fairly common problem. And that's looking at situations in audio using only your experiences, and then expecting everyone to see things your way. If you consider every piece of gear that you had access to up until now, it would account for a tiny portion of all the components being produced and sold.

With regards to the very expensive high end cables that didn't work out for you, it looks like you made some mistakes. You're kind of playing the victim here. The reality is, you went out and bought expensive cables without first making sure they will work well in your system. That's really your own fault. You can blame the cables and the gear and the store, and whatever else, but its still your fault. The fix is simple: Don't buy any cables or components until you know that you're making the right choice.
