a dealer all being well ,will demo for me at home next week,unico-remote and for comparison mf3.2, i will be "judging the above amps against my 3802 for 2 channell sterio from cd,(although i wish to use preouts from 3802 to integrated running front speakers for av use) i have never heard a valve amp, (the unico has valves in its pre amp stage, and according to dealers i have spoke to has good midrange but is more (mellow) in sound than the mf which has been described as having more (punch) i am sure the above amps will sound (differant to one another) should i just trust my (ears) as whether they are (much better than 3802, or only slightly so ,if at all) trying to get at "differant sound ,might not mean "better sound, thank you
