"Here are my first impressions: Wow
The d1-seven is by far one of the most stunning DACs I've had the pleasure to hear my music through.
The totaldac d1-seven excels at reproducing music's life, energy, and delicate nuance.
Once seated, there's a lock-in into the space and time of the recording that is at once addictive and entrancing.
Every aspect of a recording-space, sounds, movement, texture, color, meaning- are conveyed with an uncanny realness.
Come to think of it, rightness may be the better word.
If you want to hear your file-based music at its best, at the peak of its acoustic power, I recommend the totaldac d1-seven as your guide." Michael Lavorgna, AUDIOSTREAM
"d1-seven is without a doubt a premium, high-performance one box reference DAC, that cannot be overlooked by any means in the current stream of digital audio progression!"
