System in use: Schiit Saga preamp + Quad 306 (DADA and RedHill modified) + Living Voice speakers.

Comparison between:
Rpi2 + Allo Boss + Volumio + Rpi power supply
With:
2. Rpi3 +Audiophonics sabre Es 9018 + MoOde + Linear PS.

The original comparison used different output leads. I have now rectified this and the Chords have been replaced by QEDs -(Profile Audio), which I view as being slightly superior.

I have run several blind comparisons between the two, using Radio Paradise and BBC Radio 3 as sound sources.

I view the AlloBoss as being slightly superior in almost all aspects of SQ, namely: better separation of instruments allied to a more widely spread soundstage; better bass and a better ‘high end’ (the ‘high-hats’ are, for example, more pronounced). These effects were less pronounced when listening to a live BBC radio3 concert.

I am aware that these contrasts could be due to software differences. Has anyone else run comparisons?

One wonders if a different/ ‘better PS’ would further enhance the AlloBoss.

Richard.
