The Pure i-20 arrived yesterday and I'm thrilled with its competency at pulling SPDIF from my iPad 3 to Coaxial input of my Metrum Octave MkII > Nuforce HA-200 > HD800...
I'm drinking my first cup of coffee this morning, kicked back in my recliner, iPad and i-20 on the side table, streaming TIDAL and enjoying the fullframe album covers while shuffling through my favorites.
I am borderline euphoric with the quality and convenience of streaming 44/16 (except for rare dropouts!), but couldn't be more pleased with the Pure i-20 for Coaxial Out.
I haven't tested its Line Out, Optical Out or Video Out - it's doing what I wanted it to do - flawlessly, so far as I can tell right now, but I should probably buy an optical cable for comparison with Coaxial. One concern there is that the turning radius of a fiber optic cable might not be as "side table friendly" as my 75-Ohm Coaxial cable.
Frankly, I don't feel as if I have a problem that needs solving. The HD800 would reveal it. There is no noise floor in the silent portions of good recordings and there's no evidence of jitter-induced degradation of micro details. The Pure i-20 Coaxial Out is satisfyingly transparent - just doing its job, adding nothing.
Regarding stability of the iPad 3 when mounted on the i-20... The marble slab is a must-have, with its larger footprint and greater mass to anchor the Pure i-20. Some other material, like a block of aluminum could be used, but really, a less dense material would have to have a larger footprint to provide the same stability.
Unfortunately, the Pure i-20 has a somewhat porous rubber sole to which nothing adhesive will adhere - at least nothing I've tried, including Blu-Tack, double-sided foam tape, double-sided transparent tape, or even duct tape sandwiching double-sided transparent tape (to create double-sided duct tape. Nothing I've tried will stick to the rubber sole of the Pure i-20.
So, feel free to join me in laughing at my solution - that works very well:
Yes, four large rubber bands did the trick. LOL
By the way, the cheese slicer marble slab has rubber feet.
