I have not heard all the amps mentioned. I can give my two cents on the Denon, as I just recently picked up the pma2000. It is paired with a Sony 333es sacd and Dynaudio 52 spkrs. I run a Technics TT also. I find the phono stage of the Denon to be very clean, but I'll limit my remarks to the CD.
I find the pma2000 to be very detailed and dynamic. It drives the little Dynes very well. It has good presence and seems very spacious in the presentation. It has good control at all sound levels. The amp really sounds great.
Other things I determined are that it has accentuated something with the Dyn speakers, they like to be played at higher volume levels. The 2000 drives them well at lower sound levels, but I find myself turning it up louder now than before because it just sounds better ;-) I listen to alot of orchestral music and it really hits its stride there. It does acoustic strings and piano very well and voices are natural tho maybe a little thin.
Dislikes with the amp are... it lacks balanced pre-outs, unforgiveable in this class of amp imho. I also think the Dynes could use an amp that was a little 'warmer', tho I can't blame the amp for that.
If you find the Denon at $400, you could always try it, and unload it if it doesn't suit your system or taste.
