Crimson represents the pinnacle of tube dac performance. The unique 71A directly heated triode output stage with a full tube rectified power supply makes the digital audio experience warm and exciting.

The USB/DAC module allows for 32/384 PCM and DSD64/128 over DoP from an ES9038 dac chip.

$9000 for the base 71A model.

Options include:
Volume control +$750
Silver output stage +$10,000

Cosecant, really the start of the USB dac craze. In August 6th, 2003 I finished my first Cosecant USB DAC. That was the start for all USB DACS to follow. The Cosecant uses a 6GM8/ECC86 tube with parallel feed transformer coupled output. The new output transformers are wound with Cardas high grade copper.

The USB/DAC module allows for 32/384 PCM and DSD64/128 over DoP from an ES9038 dac chip.

$3500 for the base Cosecant.
Optional volume control +$500

The Brick was conceived after the Cosecant to bring more customers into this new Computer Audio technology. The Brick uses a single 12AU7A in a unique reactor follower directly coupled to the TDA1543 dac chip with passive I/V. The new N2 version is a hybrid which allows users to use 24/96 material in an NOS environment. The USB is Full Speed optically coupled and can be used with any operating system, tablet, computer or even phone.

Brick N2 $1750, limited silver $10,000
