I want Share My personal comparison between
Theorem dac / amp vs Theorem as Dac use line out + Duet
Source : iPhone 5 s
Dac / Amp : Theorem as Dac and amp
Theorem as dac Only
Amp : Duet
Headphone : VModa M 100
Cable : mini to mini Crystal cable dream line With Viablue mini plug diy
Theorem as dac / Amp :
High : more Crisp and Clear
Mid : more Clear but not as thick plus Duet
Bass : is tighter and cleaner compare plus DUET , bass more Boomy
Separation : better Theorem as stand Alone
Soundstage : Theorem as stand Alone is better more Wide and Depth .
Plus Duet soundstage so narrow
Overall : Theorem plus Duet has not so Good Synergy
It is better Theorem as stand Alone dac/ amp or
Cypher Class solo dB / Class solo original + Duet
IMO
