Wyred,
I still own the Modwright but am listening to a used McIntosh MA6300 Integrated at the moment. Also, I will be auditioning a Luxman 550AX next week. I have not settled on the Integrated I want to keep. I hope to make a decision soon but I want to make sure I've given each one the proper amount of listening time.
That said, The Modwright & McIntosh are both wonderful sounding amps. The Modwright is very neutral sounding and maintains it's composure when the volume is turned up high whereas the McIntosh starts to sound grainy. I listen to a lot of rock. At average listening levels (1-2watts RMS; 4-5watts peak) both sound great and I actually like the somewhat smoother texture of the McIntosh.
I'm looking forward to hooking up the Luxman next week. Included in future auditions will be a new, more expensive interconnect. As for the Modwright, I will be listening to it again with the new interconnect so I can't give you anythting definitive at the moment.
