Luxman M900U any experience ?

Guys thanks for your feedbacks, with 90db 4 ohms speakers droping down to 2,4 ohms can i get away with 1 single M900u or should i bridge 2 of them ?I also wonder how the M900u would mate with the Nagra Classic preamp or any other very good tube preamp ?

I have the TT2 but mostly used in my headphone rig and in DAC mode to send music to my Dynaudio Xeo 3 wireless speakers.You should get the C-900U, that would make a big difference.

@incision If you can have the C-900U on loan that would be great before making a decision.But yes the TT2 is not up to the task to drive a M-900U, you really need to demo the matching preamp.
