I recommend keeping separates rather than diving into mid tier integrateds. Perhaps get into a reference level amp like a used parasound JC5 and then get a preamp later on. I get the feeling that the equipment you are looking at would be more of lateral move than a step up.
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!
