Marantz SACD KI Pearl Lite doubts!!!

[yops]

Hi all, if anyone has this CD repro or has been enough testing, I would like to know:

 

1-The headphone output is good? It would be to move some Sennheiser HD-800.

 

2-DAC acting only as a result have? I wonder if musical warmth or is rather cold and analytical.

 

3-DAC mode only: It is possible to listen through the headphone jack? (PC via USB to DAC via USB with active but listening via headphone jack).

 

Greetings and thanks.
