Worth upgrading from Morrow MA4's?


I'm running these components in my system, using Morrow MA4's as my ICs:

Auralic Aries
Bricasti M1
ARC Ref 5SE
ARC Ref 75
Joseph Audio Pulsar

Do you think my system is resolving enough that I'd hear a big difference in stepping up to better ICs; say MA6's or MA7's (or something else)?

You should be able to hear a difference, but if it was my choice I would switch to a different brand. Call Cable Co. and have them send you some demo's.
While I'm not familiar with your sources, I am familiar with your pre-amplifier, amplifier and speakers.
IF your system is well set up to recreate the recording as it was performed, than without a doubt, your system will perform better with better cables.
I'm a dealer, so I can't recommend what cable I found best (and why I became a dealer for that cable) - but I can state with absolute certainty that your components will sound better with better cables.
Only good wishes, TJF.
Rrolack - Doubt anyone can predict with certainty whether MA6s or 7s will provide you with a meaningful improvement (barring the unlikely event someone has your exact gear and listening space and has tried). Pretty sure Morrow has a trade in/trade up program as well as in-home trial. I suggest you email or call and see if these can work together...get a trial on 6s or 7s with option to return if no improvement or credit for trade in of your current MA cable if you keep the 6s/7s. In my experience (MA3 ICs from pre to mono blocks; SP4 from integrated amp to speakers) Morrow is very customer-friendly and will work with you - so definitely worth a call (or email) to them.
