Received the unit 2 days before the expected date, nice surprise.
The wraping was excellent, you're a perfectionist taking care of his products and his clients.
It shows that we are not paying for a fancy commercial casing, switch, toroid transformer,etc; it is one of the reasons why the DAC is low priced.
As for the sound: very impressive, lots of musical informations on velvet.
I was doubtfull but it surpasses my previous excellent and well reviewed DAC. (model: PS Audio PerfectWave MkII)
I found in PCM what I was looking in DSD: musicality, presence, analogue like, a lot of musical informations, no fatigue, no glare. The digital harshness is gone, and we are far from dealing with hiding low quality softness.
I am completly revisiting my music collection, what a pleasure for an audiophile. Many recordings, previously dull and not interesting, become alive. Few of the previous bad recordings are still bad recordings when you are able to dig in the musical informations.
As you know I have a top notch and very revealing audio system (VTL MB450, Vandersteen Model 5, etc) and the improvement is clearly revealing.
As for DSD, it is working fine but I don't have enough recordings to make up my mind. I am sure it's gone be an interesting experience.
