Pmavridis, I am using a Sony SCD333ES SACD player with the Jadis Orchestra Reference.
From your room size and speakers, I would think that any of the Jadis integrateds would be fine. My room is about the same size as yours, but with an 8 foot ceiling. I am able to drive a pair of Fried speakers with no trouble, and while not a bear to drive, they are not very easy either.
Maybe I am out of line, but I would think that you don't need 8 KT90 output tubes, but they won't be a big deal either. It would just be extra heat/electricity. At first glance, I think 4 tubes would be fine. Maybe the DA30 or Orchestra Reference would be a good fit. I wouldn't step down to the Orchestra, however. Its EL34 are not as strong, but you can always use the EL34 in the Orchestra Reference if you fall in love with that tube's midrange. You would have the benefit of the larger transformers.
Good luck!
