Hello Lee Harvey,
That sounds like a great plan, as once again it was troubling me to even recommend the Supra to you or anyone else, as I do tend to try in be very resourceful while doing my research into items of interest, and seeming that it was recommended by the UpTone Audio guys to be used with the Regen, and then hearing it..............., I merely felt it deserved the attention of Regen owners here whom might've overlooked it.
In my system, it simply steps aside and presents every single note in a rather smooth manner, yet with very nicely detailed top ends and some of the best bass I've encountered regardless of its price, but my offer stands..........., if you don't like it?, I'll be happy to buy it from next Friday. I simply hope that you hear from it what I'm getting at this very moment?, as it might be simply that it's system dependent or just plays differently with cables with other sorts of metal conductors?, I can't say as my IC from the iDSD is military spec'ed heavily silver plated copper using wire from NASA that's over 30 years old, with the Supra which is tin plated copper much like the cabling from the 30s into the 80s like Western Electric amongst others, and then a copper based AC cord and Speaker Cables where the combined sound is very very very much to my likings in many ways even more so then when the other USB cables are in the system..............., yet I've my fingers and toes crossed in hopes that it does work out for you?, as it's a very beautiful sound overall.
But I'll be following your findings either way.
