I purchased my DK VS-1 Reference MK II integrated amp. from audiorevelation.com (Jay is owner). No shipping charges, bonus package of some Cardas IC & stuff. Sounds pretty good, added 7308 tubes ($50 Upscale Audio each) have ordered CCa, tubes brought unit into easy "Class A" territory, added Analysis Plus power cord which was more than a subtle change in all aspects. Not sure about phono pre section yet but am sure it is more than just ok-good-serviceable. Previous amp was Audion 300b, very nice but no oooommmphhh, so far enjoy this more, best wishes, cheapmike.
