Hi Frank, I'm trying to decide which preamp to pair with a Vision SET 120 amp. I've narrowed it down to these two or the Vision SLR. Could you explain what the sound differences are in the Fet Valve CF SL and the Transcendence 10 SL? What does the extra $400 get you? Although the basic volume/mute remote on the two limited edition preamps would be all I need, I'm curious about the panel light dimming feature on the Vision. I've got a Warwick bass combo amp with a blue LED power on indicator that is so annoyingly, blindingly bright I had to put a piece of tape over it. Is that the case on the Fet Valve CF SLR or Transcendence 10 SL? The fact you've added the dimming feature on your new remotes makes me wonder. Although I'm leaning towards one of the tube units, I'd maybe rather go with the Vision just to avoid having a blue laser beam burning my retinas.
