I use the V-1x with my Eidolons as my reference setup and would say they are a match made in heaven. The liquidity, wide soundstage, and instrument timbre were spectacular. They had that 'cut from the same cloth sound'. The bass is quite good, but it does not produce the thunderous bass of a monster amplifier.
I tried a few other amplifiers with the Eidolon's and my rankings are:
Ayre v-1x (transparent, tubey, great timbre and soundstage)
Rowland 8tihc (a very good choice. nice timbre and POWER, but not as transparent or alive sounding)
vt-100m2 w/kt88 (underpowered but wonderful sounding)
Aleph 2's (astonishing resolution, sparkling fine detail, but not enough power)
McCormack (not clean enough for eidolons)
vt-200m1 vt-200 (had old tubes, so didn't sound good)
BEL's (dry, transistor sounding - these were old mark II's)
