I just traded in my Esoteric F-07 for the new Michi x3, Series 2 that includes their new 8-Channel ESS SABRE ES9028PRO DAC (you can still use an external DAC).
I have had several previous integrated SS (Musical Fidelity, Rotel, McIntosh hybrid), Class D (Primare), and Tube amps (Prima Luna, Modwright, Cary) and this by far has been the best sounding paired with my B&W 805s. The bass is so much more prevalent that I no longer use my REL sub.
Build solid, almost Apple like in its appearance and packaging, and seems to weigh more than its 64 lbs. Pricing is about $5,700 which I would say is under priced compared to integrates of similar quality and specs.
