Wow-tough crowd here! It’s getting a bit nasty.
I may as well throw in a few comments.
Firstly, Dopogue is absolutely right about cable burn in, especially on phono cable which is subjected to such a small signal under normal circumstances that it may never fully break in. Which is why I strongly recommended anyone purchasing the Audio Sensibility cable earlier in the thread pay the extra few bucks for the optional burn in.
For the past 10-15 years every piece of cabling in my system has been cyrogenically treated and then burned in either on the Nordost cooker or the Audiodharma including all 4 phono cables that I’ve used over the years. Both Steve at Audio Sensibility and Gene at Takefiveaudio (who built a custom phono cable for me years ago with Cardas wire) use the Audiodharma.
Secondly, the Jelco phono cable (at least the Jelco 506 balanced/XLR version I used) is not poorly constructed, nor does it sound like junk. Is there better out there? I’m sure there is. For the price, though, I think it is a good, very high value cable which bettered both the Cardas wire/Din/Vampire XLR cable which Gene constructed for me and Van den Hul 502, which I believe is the stock cable included with the upper end SME tonearms and retails for around $450.
In my opinion, the Audio Sensibility Impact SE copper cable easily bested all of these though as I said earlier, and not by insignificant margins. For perspective, this is on a Gyrodec with Sumiko FT3/Jelco 750D arms and an AT 33 Mono & Accuphase AC2 cartridges into an Aqvox phono preamp.
Whether the differences would be as pronounced on the OP’s equipment I don’t know, and then subjective listening preferences, as always come into play. I hope the Audio Sensibility works out for him, or the Jelco, even though I consider it to be considerably inferior. And the DH Labs might be interesting as well. I have no experience with DH Labs interconnects but do use their power cabling in my system and it is a very high value cable.
Finally, Mogami (real Mogami-not fake) manufactures a lot of different wire, almost all of it reasonably priced. But there are certainly lower quality lines within Mogami that possibly do not offer much in terms of performance.
Their 3103/3104 speaker cable, for example, is anything but junk. The 3103 outperformed Kimber 8TC in my system at a fraction of the price (about 1/6th of the cost actually) and there are many 3103/3104 users that have compared it to much more expensive offerings and are using it in moderate to high end systems with very good results.
Finally, if the OP is indeed using wireless speakers and the signal is ultimately being digitised, it would seem to be self-defeating in terms of investing a lot of time and effort into an analog front end.
