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?

initforthemusic:  Please keep us posted as to your impressions of the SP7s.  Thanks.
Ok bondmanp. Just have to allow a bit of time for shipping to Australia and cable run in time, but will definitely give impression of cable.

Cheers.
@bondmanp I just received an email from Morrow and my cables have only just been shipped! Read on their website that Morrow have moved premises so orders delayed. So it will be a while before I can report.
Thanks, initforthemusic.  I just yesterday decided to try out Morrow.  I ordered a 2 meter run of MA3 interconnects with the Eichmann copper RCAs.  I also ordered the longer burn-in service, so I am looking at about a month or more for delivery.  Patience is a virtue!  I will post my impressions here as well.
I had the Morrow Grand Elite Reference SC's and thought they sounded very good. Next I tried Cerious Technologies Graphene Extreme SC's and it sounded like I added perfectly integrated sub woofers, that's how much these cables changed the bass. Of course the cables add nothing but they allow more music through and they sound so very natural. CT cables just might the biggest bang for the buck out there.
