Pros: Stunningly clear, transparent sound, excellent digital volume control, perfect size for headphone setup
Cons: USB does not support 88.2kHz sample rate (but DOES do the much more common 96kHz)
My full review:
In summary, this is one of the best DACs I've ever experienced, which is surprising since it only costs $1300. That's a lot of money, but actually pretty low for a top class DAC, which is what I consider this to be. In my personal experience I rank it below the Resonessense Invicta ($4k), MBL 1511E ($8k), and very very slightly below the now discontinued Anedio D1 ($1230), but above the Audio GD Reference 7 ($1900), Esoteric D70 ($6500), Wavelength Cosine ($3500), and of course all the usual suspects from Lavry, Benchmark, Grace Design, Musical Fidelity, Cambridge Audio, etc.
This DAC at $1300, paired with the matching Violectric V200 ($1k), makes for an ultra high end reference system that compares to almost anything out there.
