The ML 585 is the second favorite integrated amp that I have heard and could afford to buy at that time. My favorite was the KRELL K-300i which I bought and sold to get a KRELL 175XD stereo amp. I just sold that XD amp to raise funds to buy another more powerful XD amp in the near future.
I preferred the ML 585 and the KRELL K-300i integrated to the Luxman 509x and the older Hegel 360. I was told by a ML dealer that the older ML 585 sounds better than the new ML 5000 series integrateds, though the new ones have a better internal DAC.
