Cypher Labs Algorythm Solo with Just Audio AHA-120I've compared this Class A amplifier with the Theorem before; I put it as the Theorem's spandex versus Just Audio's silk. Not to say the Theorem is a slouch, but when compared to a Class A amp it sounds slightly less good! And that's the tradeoff - if you want no compromise in sound quality and wish to pick every component you will pay for it, and you will have to carry it around as well!
DACs Compared OnlyFor this test I decided to get a decent portable amp (Fiio E12) and compare the Line-Out features of the HP-P1 and Theorem. Things were not all that different in comparitive terms.
- The HP-P1 had good detail but the presentation was flat with a limited soundstage; a bit on the dry side.
- The Theorem had a wider soundstage but was still a little dry sounding. Detail was similar to the HP-P1 but again with more control.
- The Algorythm Solo was a slight let down used in combination with the E12; soundstage was decidedly average with a flat feel to proceedings. Detail was comparitively muddy sounding.
