I actually did not buy that one, I did the mod myself testing a couple other caps as well. Mine appears to be decently forgiving, using a Bifrost 2 as source.
That might explain it. I almost got the Bifrost 2 since I've owned the Gungnir MB and Yggdrasil in the past, but I ended up going for an RME ADI-2 DAC instead. The RME leans a little analytical, but it's features make it very flexible and tweakable. The mod just made me wonder if the stock cap choice was chosen to placate people who thought GS-X Mk. 2 was too aggressive. I'm really impressed of the micro-detail the Elna caps bringing out, though. Even more than the Liquid Platinum run fully balanced.
Running the HD-650 balanced out of the LP is still edging it out for me with it's silky midrange and sense of space, but only in balanced. The Irony is I've long been a balanced naysayer because I've always thought the improvements would be minor relative to the cost of a properly implemented balanced design. It makes me want to hear the HD-650 out of the GS-X Mini now. It's still more than I'm comfortable spending on a single amp, so I'm hoping maybe once the dedicated power supply is released for the GLite Mk. 2, it may improve it similarly. As the GLite Mk. 2 is with the mod now though, it's just super clean and detailed without getting into fatigue. When I say "less forgiving", I just mean it exposes poor recordings a little more.
