Interesting. I had a look at the Pink Faun and at the TNT review. You have to wonder why, though, it hasn't found much favor though it's been around for several years. I think that perhaps it may have been the recent and rapid improvement of USB to I2S converters like the Singxer SU-1 and the LKS USB-100 (the latter being the same circuit as in the upgraded LKS 004). Both of these accommodate DSD and PCM and have received wide acceptance, and can be used with lap-tops. Also, do you know why PF charges a premium for the LKS version? Isn't it just a matter of making up the cable (HDMI to HDMI, or HDMI to RJ45) to accommodate?
Looking at the Pink Faun lit. they make a great deal of the file to USB within the computer as though it's some sort of massive "conversion" which I think is really overstated.
In any event you might want to consider whether doing without DSD (in native form) when running the LKS is a good idea. I have had a lot of success with SACD rips (especially "pure DSD" from analog originals) and at least one correspondent at the Asylum writes, "
With DSD512 [using HQPlayer to upsample from red book] the LKS sounds like an analog rig". Though upsampling rb all the way to DSD512 seems like a mighty stretch.
Of course, as usual, YMMV.
