A wonderful sounding amp, very warm and voluminous sounding, really beautiful timbre, strong and dry but not bloated bass, very smooth treble, for some definitely too smooth and surely a cure for speakers / room acoustics with harsh treble, therefore not very detailed but still lively sounding, much much better than ECI-3.
The big drawback for me was the soundstage. The amp seems incapable of processing the spacious information delivered by the source. Instead it builds up it's own soundstage, no matter what the source is. It's wide but not higher than the speakers. And there's no depth whatsoever, it sounds just plain flat.
Others will undoubtedly have made different experiences with this amp.
