Worth upgrading from Morrow MA4's?

Rrolack - I own Clear Day double shot gun speaker cables as well and think they
are great. But fyi...Paul Laudati/Clear Day does sell ICs...search for Clear Day or
VonWaffen either here on A'gon or on the Audio Asylum Marketplace. There are
some on AA Trader now.

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.
