A. Eidolon v. JM Lab Utopia


Any thoughts about the differences?
gladstone
Gladstone, my dealer demonstrated the Eidolons in a 16' x 24' x 10' room and they sounded great there. Not a bit of problem filling that space with music.
The Eidolon is a superb speaker but requires IMHO plenty of high quality power to bring out its best. I found ARC Ref 600 worked best.Sounding staging, timbral accuracy and speed are its outstanding attributes. Only beaten by the
(more expensive) Pipedreams, 7' Reference my current speaker. The Utopia (not Grand) is less refined (ie musical)and the bass is not as 'accurate', but otherwise a great speaker.
I've had Eidolons for the past 10 years now and a good buddy of mine whom I swap gear with has ALto Utopioa Be's.

Fast bass, midrange presence and palpability... Eidolon.
Silky highs, buttoned down comfy sound, and bass extension... Alto.

You need to listen to both driven with moderately powered amps (we both used NP100Premium golds) for a fair comparison. Eidolons are a lot more difficult load but the Altos have putt putt muddy bass when underdriven.
