Arthur,
I played trumpet in my distance past and still own two horns (sentimental reasons) and that experience has me value tone, timbre and harmonics of instruments highly. If a component can't preserve the natural tonality and body then I'm not interested. Attending CES 3 times in the last 5 years, it's startling that some well regared and praised equipment is very "hifi" but lacks natural tone reproduction. There was a definite tendency toward a lean, thinner and less body type of sound(drier as well) that isn't authentic (at least to me).
You have obviously owned many fine amplifiers and I'm sure you know what you like. Have you heard any of the First Watt amplifiers and if so what's your impression? Your speakers permit the use of a wide range of amplifiers to explore.
