Morrow SP7 Upgrade.


Currently using Morrow SP4 Speaker Cables on Low Frequency (bass) in bi-amped system. Various Speakers used, at the moment Revel Ultima Studio. The Morrow's sound best of the cables I have driving low frequencies. At the moment Morrow have 60% off in their trade up program, (I would trade up SP2's I have in a budget system). Anyone have experience going from SP4 to SP7's, and how much better? What other alternatives for bass frequencies would you suggest if not the SP7's?

Or on the other hand, making a very fine product at a very cost effective price. I know I am far better off for purchasing these and getting better sound is what we should all be aiming for.
Meanwhile, back at the topic,... I was listening last night to random tracks on the server, and Sheryl Crow's "Home" came on.  Whoa!!!  Repeated chills up my spine, huge soundstage, emotional impact in spades.  It was almost overwhelming.  I wish every bit of music I like would hit me like that.  This cannot be completely attributed to the MA-3s, but at least they didn't ruin it.  And that, I think, is all we can ever ask of a wire.
Excellent bondmanp. Received a batch of CD's yesterday, so had a long listening session. The SP7's have really settled in nicely, getting bass reproduction I never thought was possible from CD playback. I've tried a few different combo's and the SP7's on bass & Cullen's on Mid/high is definitely doing it for me.
Some of Sheryl Crow's stuff is really done well.  A good recording really excels with a decent system for sure.  
I ordered the MA5 on Sept 3, with Eichmanns and a 10 day burn and from what I've read, arrival could take almost a month.  In the mean time, I ordered a pair of MA1.1 since their trade in program makes prices so attractive.  The second pair I've only asked for their 2 day burn, so I might well receive the 2nd pair before the first.

Either way I'm psyched as I've only had the MA1 and MA3.
