How good is the Musical Fidelity A5?

How is the A5 different from the 308, besides the obvious tubes?

I have this CDP and really like that it is not sterile at all. It throws a great soundstage and all around is a very nice sounding player. I couldn't audition the Audio Aero Prima or Lector players that I was also considering but the A5 put an end to the search.

I now have the A5 and IMO this is an extremely good machine. Once it is on for a few hours sterile is the last word that descibes the sound. There is almost nothing to complain about. For reference, I owned many machines in the past several years and each had much to complain about. Here are a few: Cary 303/300 Simm Equinox Marantz SA-11 Naim CD5/Flatcap Esoteric DV-50 ARC CD3MK2 Wadia 860X. The A5 delivers a well balanced sound, deep far back soundstage, excellent dynamics, very good extension and definition into the highs/lows, very good imaging, fast and quite transport.......hard to go wrong with this one.

Has anyone (besides Stereophile) compared the A5 to the Trivista? I loved the Trivista in a short demo in my system and am considering the A5.

What DAC, if any, would you recommend as an upgrade for the Musical Fidelity A5 cdp? Would a mhdt Paradisea+ offer an improvement? Any other suggestions?
Thanks
