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 just got an email from Morrow yesterday informing me that the cables are in the mail.  Right now I'm assuming that they are shipping both together, they should be here by October 2, so under a month with the MA5 and a ten day break in service.
I've had excellent results from my now broken-in (around 37,000 hours) Morrow cables (got one free in a promotion…another MA1…their email promotions are endless and effective). The most recent is an MA1.1 balanced cable running from my DAC to my preamp, and maybe it sounds better than the AQ it replaced, but that's hard to tell (good balanced cables in actually balanced gear often defy one's ability to hear differences), but suffice to say my system's overall sound has improved by exactly 7.2% (or 8.7% if good weed is utilized…hey…it's legal here). Worth it.
Wolf, thanks for your impressions, I've got a pair of their MA1 too.  When I use it on the preamp to amp jumpers (Nad C375BEE) the bass gets really tight.  Some might say less, but I prefer to say, "tight".  Also, highs seem cleaner or more focused.  Not sure why.

Up here in Canada we are big weed growers, but I'm afraid the strongest thing I take is maybe Advil, or caffeine in various Starbucks or Kicking Horse varieties.  Too much caffeine makes the music sound "shaky".
Okay, the Morrow MA5 came in yesterday and I've got them going from cd player to integrated amp.  Everything has improved.  Bass, vocals, highs, imaging.  I think it's really just more detail getting through, which improves everything, but it's really something.  I had the 10 day burn in, so they have 240 hours on them already.  It seems like I can turn it up more too, and it just stays clean and clear.

Note, I had a lesser cable on the pre amp jumpers, and now have the MA3, so that's gotta help too.  Both of these Morrows have the silver Eichmanns.

I thought the MA1.1 might get here first, or get shipped together with the MA5, but no dice.  I ordered them a week later, so they'll probably arrive a week later or so.
Early this year I purchased Morrow Audios MA5 interconnects terminated with Eichmanns superb silver RCAs for a headphone system consisting of Linear Tube Audio MZ2S preamplifier , ZMF Eikon phones , PS Audio Direct Stream Memory Player and Wyred4sound 2v2 LE Dac.
I did try other popular brand interconnects over the summer however the MA5 are an excellent bang for the buck with further improvement of replacing the chassis rca outputs in the dac including the chassis rca inputs of the preamp with Eichmanns silver RCAs .
It was clearly evident I was not hearing the full potential of this Ps Audios new Direct Stream Memory Player and Wyred4sounds new reference dac . You can be sure the majority of manufacturers will use inexpensive mediocre chassis inputs and outputs for cost saving reasons , most definitely Morrow Audios MA5 with silver Eichmann RCAs used in the mix are a winning combination.
