Introduction:

 

 
Thank you for purchasing a ModWright Instruments product.  This unit is designed to offer high 
performance and exceptional reliability. 
 
The ELYSE Tube DAC offers high bandwidth, low noise and distortion, and exceptional 
musicality.  We have designed this DAC to allow the reproduction of all digital recordings in a 
way that is accurate, transparent and musical. 

 

The ELYSE DAC has a direct-transformer coupled, all tube analog stage with zero coupling caps 
in the signal path.  This gives the analog signal the greatest fidelity and most natural and 
resolving presentation. 
 
The ELYSE DAC digital processing includes both data and clock buffering via a unique digital 
algorithm. The result is vanishingly low jitter levels and the greatest detail for all formats, from 
16/44.1 Redbook recordings, to 24/192 hi-rez streaming. 
 
The ELYSE DAC was designed purposely with a tube rectified and solid-state regulated power 
supply.  Different types of rectifier tubes may be used in the ELYSE DAC, safely, and allow for 
different tonality and presentation, to suit the taste of the listener.
