I have a set of Morrow speaker cables (SP2 or 4?) about 4 years now. I was neither dissapointed nor thrilled with any difference in sound. They are well-made, very bendable, somewhat unique in design and length to order. These days I make my own cables with Belden bulk wire (spools of 14x4 spkr & pwr and 1694A Brilliance for coax & RCAs), but I wouldn’t want to hassle assembling all those strands in the Morrow design - so the value is there (when they’re on sale). Morrow used to sell used trade-in cables (Morrow & other brands), and that’s how I found them years ago - does anyone know if they still do that? The Morrow’s I have are on GoldenEar Tritons, so there is very little power demand since they only power AMT and mids (not bass), but they sounded fine on the Martin Logan e-stats too (which dipped to 1.6 ohm load).
I also have a very nice set of AQ Mont Blanc (think 10awg) with DBS and factory upgraded ends - no discernable difference between them and Morrow (or my DIY Belden) in my experience - maybe a difference could be found by precision measurement.
My impression is the Morrow spkr cables are made of MANY very small individually insulated solid copper strands, and I contemplated making my own from Ethernet cables, but who wants to wrestle with a zillion tiny wires?
