Made a new cable for my Q701 today. I destroyed my Sextett's cable that uses Mogami W2893 and converted it for use with my Q701.
You know what is the worst thing in the world? Soldering Mini-XLR plugs with no "helping hands" (metal thing that holds plugs etc) or vise. What made it even worse is that this new soldering iron I bought was so worthless it'd take about forever to heat up anything. I need to return it and invest in a good one.
The cable basically sounds the same as stock, but with some minor improvements. I think it has a higher capacitance than stock cable and similar to the stock HD-650 cable, but maybe a little lower. The biggest difference i'm hearing is everything is a bit smoother and fuller sounding. Perhaps a bit more detail. You can say subtle improvements, but pretty nice. No changes in sound signature obviously.
It really takes specific songs to hear the difference. I used mostly anything with a large soundstage. Live recordings are really the best.
It does sound like the mids are more forward but I think this is virtually impossible and I think it's just more revealing of crappy recordings. Most of them are known by me to be bad anyway.
I previously tried to make a Canare Q701 cable, but it was rather muffled sounding and worse than stock.
So if you want a nice upgrade for dirt cheap, make a Q701 cable with Mogami W2893. I should note that you need to cut off a piece of the Mini-XLRs bottom plastic piece in order for the thicker cable to fit.
Total cost is less than $10 probably! Out of maybe 4 Q701 cables i've tried, this one is slightly better than stock. All have been worse. The ALO SXC one was technically better, but it seemed to suck the life out of my Q701 and make it less warm. Makes sense. I loved it at first. Low capacitance wire stinks on the K701 and Q701.
