both excellent
gryphon > luxman by a little
but both are a good bit above your r11's in relative quality level....
Gryphon Diablo 120, Luxman L-590AXII, Other? For KEF R11
I have a MyTek Manhattan II and Parasound A21+ right now paired with my KEF R11’s. Use the MyTek as preamp/DAC/streamer - considering replacing it and the Parasound with an integrated. Have the opportunity to pick up the Gryphon or the Luxman for a good price -any thoughts on what may be a better match for the KEFs? Any other suggestions for a good match in a similar price range? Thanks!
