Parasound gear is nowhere near Gryphon. The Gryphon 120 and Luxman 509 are on another level from the JC5. I auditioned the 120 and 509 extensively and went with the Gryphon 300 only because my speakers are a tough load. The 120 is a sweeter sounding more ballsy amp than the 509, a good match for your R11s most likely.
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!
