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?

So, in your mental travels what did you finally come up with, Pumpkin?
Well, the MA3s arrived yesterday.  I am glad I did my homework and knew what to expect... otherwise I would have thought they were somewhat unsubstantial for the money spent, in terms of appearance and weight.  But, I guess that is the point... the things that make other cables thick and heavy (and less flexible) don't necessarily help the cable perform well.  Perhaps, the opposite is true.  The felt bag is a nice touch.  The quality looks good, the Eichmann copper RCAs seem securely attached.  The assembler's names (Matt) was written on the labels.  Nice touch.  I hope to get them in my rig tonight.  
Geoffkait…your incessant and weirdly snarky little comments simply make you seem like a weirdo who can't resist stalking me with inane, unfunny posts…do you need more friends? Are you simply lonely and sad? Need a hug? Not sure exactly why you feel compelled to continue this pointless endeavor, but know that it only serves to render your already sketchy position as a pseudo expert even more suspect. 
Hey wolf, just a heads up. If ever you are looking to upgrade. I set up a system for a mate around 2 1/2 year ago. Just put in budget cables, Morrow MA1's was one of the I/C's, as get better components and look at upgrading cables later when budget suits. Took around my MA4's after 12 months, took his system up a couple of notches. He traded up @ the 50% off and is pleased. I only ever buy or advise to buy when Morrow cables are heavily discounted, I think they are good value at the big discounts, maybe not as much at the standard discount.
