I've got a 5 year old Kenwood DPC-661. I'm thinking about an upgrade, primarily because battery life totaly sucks. 2 1/2 CD's on a set of AA's.
Anyway, it actually sounds pretty good, IMO, and drives my HD600's to ear bleeding volume quite cleanly. 10 second anti-skip is supposed to be compressionless, and high power amp.
The bass is full without using boost. mid's are clean and highs only slightly rolled.
No jogging, but works well for long walks in the morning. Sometimes I'll use my TA, but most of the time, I don't think it needs it. The TA really helps the output of my HP N5270, and my DSP360 that I use for B5 and Farscape.
The little Kenwood sounds pretty good just by itself.
Maybe I'll just keep it for now. Line out sounds like a good idea, but semi-retirement makes me think before I buy.
Oh yeah. Batteries at Sam's or Costco are pretty cheap.
