Best imaging up to 3k used?


My speakers are warm, so I am looking for the faster, brighter type of sound.

Great imaging is my no1 goal. (3D , instrument separation)
PRAT no.2 (speed, dynamics, flow)

Redbook files only, DAC / streamer with analogue preamp preferred

I have listened to Benchmark, Naim and Mytek. They should work well with a slightly warm and musical speaker.
Look at a used Mytek Manhattan.  Very clean, uncolored sound, has both digital and analog pre-amp.
Maybe a used Chord Hugo TT or Ayre Codex would work nicely for you.  I'm using the Codex and the imaging is very good and the music is very clear and detailed.   I heard the TT a few times and it's very detailed and clear.  
I like the idea of the battery powered and capacitor buffered Hugo TT. How is the Hugo TT in terms of dynamics ? I had the original Hugo for some time and found it lacking in dynamics and image density.

How is the Ayre Codex compared to the Hugo TT?

I have an eye on the SOTM SDP 1000 ex which has an analoge preamp and battery power too.
