It's been up for a while now: https://www.head-fi.org/showcase/ifi-ipurifier-3-0.23374/reviews#review-21639
Just to stay on topic, I have to say that the Meze 99 Classics and the iFi xDSD are the PERFECT match! Anyone looking for a versatile DAC/AMP for their 99 Classics should really consider the xDSD. I have clocked in many a multi-hour listening session with the pair, and bar none the sound is addicting! Both XBass and 3D+ sound phenomenal with the 99 Classics (no surprise as they take to EQing really well). It's almost like the folks over at iFi finished the prototype of the xDSD and asked the question " But does it sound good with the 99 Classics? " as the synergy between the pairing is above par, heck, dare I say perfect match!
For me for some reason I judge with the way the treble sounds and the treble being spot on with the xDSD.
Not cheap but seems to go further in bringing out the best the classic 99 has when compared to the S2 digital also the xDsd makes the bass tighter with less bloated sound.
All in all I agree with the praise Bansaku is on about.
Just keeping this in mind about not going too much off topic hah.
