Both quality products.
Hegel 390 may be better value. Includes streamer, DAC 250wpc, insane damping factor. $6,500. Plain looking.
Lux 509- Has all the TT inputs, tone, balance, meters & beauty. Also better SQ. 120wpc. $10k.
Hegel is a little dry by comparison.
If you had a larger room with speakers that want power the Hegel may be the one.
Otherwise your desired SQ description sounds like the Lux.
