The Avalon Ascendant is their new entry level model. At $8000+, thy are not inexpensive. But at a 1/4 of the price of the Eidolon Diamond speakers, you hear 70-90% of their attributes. The soundstage was wide and deep with almost pinpoint imaging. The bass was very good for such a small speaker, Mahler's 1st Symphony was as realistic as you could possibly have with excellent dynamics and bass. The transient response with cymbals was also very good. Vocals had well defined pitch and nuiance. The tonal balance was fairly neutral, with a slight prominence of the upper bass. The speakers transparency and presence are not in the same class as planars or electrostats, though very good for a dynamic speaker. As far as electronics go, the Ascendants sounded cleaner, more dynamic, and the resolution, the ability to pick out every little detail on the CD, was the best with Spectral. The Audio Research, was not up to par with Spectral in virtually every respect. Overall, the sound was clean with excellent soundstage and imaging, the hallmark of Avalon. If you are into dynamic speakers then I would give a listen. By the way, the fit and finish are still first rate another Avalon trait.
