Densen B120 Limited Edition Integrated Amp - How good?

Does anybody here own the Densen B120 LE integrated? How does it compare with the likes of Rega and Naim equivalents?

Lastly, where does the B120 LE stand among the Densen integrateds? Is it a much better sounding unit than the B110? How about the B130, B150 and B175? I am not looking so much at power but the sophistication or refinement in the sound.

I read that the preamplifier stage of the B120 is based on the B-250 preamp, and the power amplifier stage is based on the B-150 integrated amplifier, a 2x75w version with the same circuitry.

Any advice would be appreciated.
