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?

I estimate I put about 50-60 hours on the SP7's in my little system. Had a music session with a few mates yesterday and the 2nd half I put the SP7's on my Revel Ultima Studios bass frequencies ( hey there driving two woofers each so I figure there getting a reasonable workout). Very pleased, been giving them a bash today so I figure they have roughly 110-120 hours (inc. the 2 day break-in). I feel they are on the upward spiral, after that little ragged period. I'll swap them over to the HF posts in a day or two, could be interesting. If they keep improving as per the info. sheet I'll be very happy.
I laughed at myself while breaking in these cables but figured, hey, I gotta see if this stuff is as advertised…I actually had white noise from a rarely used tuner running through them all night for a week or so, and then just ran my rig as usual when I was home…turned off the tube amp and let the tuner noise run while out (all the while wondering if signal really does travel through a cable driven by a preamp toward an amp that is off). Then you listen for whatever the instructions predict will happen assuming you have a grip on how much time has passed...In any case, worth the wait for an amazingly inexpensive (seriously…50 bucks) cable that seems to sound fabulous.

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.
