Its not about the review. I think you just are being fed advice for if and when you decide to go down the Lampi rabbit hole... Personally, I would KILL for a SE GG Lampi right now. Why?
Simple, I would not have to wonder if the Gucci parts/copper case make that much of a difference (point would become moot), I would love to have the metal base PSVANE 101d as my stock tube and finally it would mean having DSD256 right now, rather then later when it can be retrofitted as an upgrade. I, like you, am a DSD junkie plus I want to upsample as high as possible with HQP with a powerful computer. JRiver sucks for upsampling and even free Foobar crushes it. JRiver is sweet for media handling, but not upsampling.
For making sure the Transport transmission is really clean to feed the Dac, there is talk that the Corning optical USB and the Uptone Audio Regen device is KILLER and simplifies things greatly at very low cost ($300 max before stepping up to a well regarded 7-9v LPSU).
