I have. Anything specific you'd like to know?
The medium level pre has a well balanced sound and good harmonic rendition. Details were good (not superlative). Their "big" (=very expensive) sounded to me better by far, and that includes a very good riaa. Reproduction was extended on either end and tonal/frequency balance seemed very good (i.e. no reproduction valeys or harshness -- i.e. mid-high frequencies over emphasized, low/mid frequencies underemphasized, etc).
I've only listened to their floor standing amps (outrageously expensive) driving horrible sounding spkrs -- so can't really comment.
