An F8 feeds my Focal Aria speakers, which are rated at 89.5 dB sensitivity. Does a great job, as loud as I might ever want in a typical modest room.
A Van Alstine Transcendence RB 10 tube preamp feeds the F8. I recently put an RME ADI-2 DAC in to feed the preamp.
All in all, it is noiseless, musical, plenty of detail, and neutral.
