That's is correct no chip set. A custom priority design does the job just right.
With an outboard regulated tubed power supply and the DAC section utilizing a DHT Triode design sporting 101D tubes you will hear digital as never before.
Natural tonality with harmonics you can hear and feel. The bass if your speakers are capable will come up through your feet.
PM me for a demo. Introductory price is $5500. USB not included. We prefer a SPDIF/USB converter. However if you insist we can offer a USB input. Photos coming.
