I recently purchased the VAC Sigma 160i integrated amp with MC phono and balanced input.
This integrated amp is detailed but liquid and smooth and the bass is completely authoritative without any bloom. The 160i is neutral (not tubey at all), with great air, transparency, and top-end extension. Soundstaging is deep, wide, and tall with excellent image density and separation.
I admit I was very, very hesitant to give up my separates, especially my Art Audio Vinyl Reference. The MC phono of the 160i, like the VR, uses Lundahl transformers, has a very similar sonic character, and to my ears is every bit it's equal. Due, I suspect, in no small measure to the short signal path and common ground made possible by the integrated platform. IMHO, Kevin Hayes has truly designed a tour de force for the vinyl lover.
I have absolutely No Regrets musically, financially, or aesthetically! The VAC integrated allowed me to get rid of three HRS isolation bases, three expensive power cords, and two pairs of reference interconnects - an investment about equal to the separate components. My music room is a whole lot less cluttered-looking to boot.
For anyone looking for true reference level amplification in an integrated package and who has speakers that can be driven with 85 tube watts per channel, the VAC Sigma 160i may well put an end to your search. I give it the highest possible recommendation.
FWIW, I have also owned the ASR Emitter Blue and can say the VAC 160i beats it hands down. Also, the ASR is really more of an "integrated in function" amp, than an "integrated package" because it is not a one-box solution.
Footnote: While the VAC "Alpha Integrated" was the 160i's immediate predecessor, the 160i is not in any way a derivative of the Alpha Integrated design. The latter was a merging of circuits already developed and used in the Phi preamp and Phi amps. The Sigma 160i was designed from scratch on a blank sheet of paper. This no doubt accounts for its almost magical musical reproductive abilities. While it lacks the "eye candy" and "audio jewelery" qualities of the venerable Phi Beta 110i, it is in every other way a most worthy successor.
