Hi, A happy hello from Scotland in the United Kingdom. A happy Ma5 and DIG4 digital owner here, recently decided I needed Morrow speaker cables i my life. Ordered a Biwire set of SP7s with 4 spades at speaker end, 2 spades at amp end. Took up Mikes 10 day burnin service, so approx 240Hrs on the wires already, and from experience of my MA5 and DIG4...the (infamous) Morrow burnin is a real thing, and has been accurate time wise. A question ? RE: the biwires construction, the SP7 has 120 runs of SSI? At the speaker end its split into 4 runs for the speaker terminals, is this 4 x 30 runs or 4 x 120 runs? (suspect 30?) Also, the Morrow literature specifies at the 4 core speaker end which speaker terminal (LF pos/neg and HF pos neg) each of the 4 colored cores attaches to. Are the 4 cable cores at the speaker end divided up equally? Just wonder if one pair has more cores than the other (red/black vs blue white) and therefore might be better suited to the bass driver terminals which draw more current than the tweeter. *DISCLAIMER* I'm a lifelong audiophile tweaker and look for these things to (perhaps) improve things! Suspect though the cable construction is 4 x 30 (of the 120) and if so...I'll rest easy. By the way, My previous cable was a British high end cable Tellerium Q Ultra Black which retails at £343 per meter. https://telluriumq.com/ultra-black-speaker-cable/ With 200-odd hours the SP7 sounded way WAY better and I know it will improve significantly more.
