Years ago I acquired a pair of Avalon Acoustics Eidolon speakers. They are just remarkable in the holographic sound, clarity and nice bass. I drive those with an Ayon Audio Triton III KT88 tube amp. Ahem.
You might think that was enough, but in my home office I have recently upgraded several older speakers with Legacy Studio HDs paired with a Lyngdorf BW-2 sub ...driven by either (I change it) a Raven Audio Blackhawk LE 6L6GCs -or- a newer Octave V70 6550s. I’m knocked out by the sound of these speakers with the tubes. I’ve got a lot of room treatment in this space, primarily furniture and 1 foot hex sound panels along the wall near the ceiling. Those actually make a very nice dampening difference (the 5x5 glass window would otherwise be a mess).
