Mark Levinson No.32 vs Mbl 6010d vs Bat Rex?

I don't know how it compares to the MBL or BAT linestage, but, I own a Ref No. 32 preamp. To me, it is a somewhat dull and lifeless sounding preamp compared to my current tube linestage. I tend to think the same way about ML amps -- they are on the "darker" side as well. I am sure the sound complements certain systems, so I certainly won't say it is bad sounding at all, it just doesn't quite fit my current system. I've kept it (its on loan to a friend) because it is VERY versatile, flexible, and ergonomically great (on par with the BAT and Boulder gear in those terms). On the other hand, gear from the same manufacturer is more likely to develop some positive synergy, so you may want to at least give it a try.

In other words, it would not be my first choice for adding a bit more life to the sound.

That'''s very helpful, Larry. The main reason I put the no.32 on the list is their very fine ergonomics and conveniences. I also found the no. 33 a little dull or may I say "polite" but I think I solved that problem now by replacing all the caps with Blackgate caps throughout as well as the op-amps.
Now any body can tell me about he BAT REX vs MBL 6010d?

I have past experience with the Ref 32 feeding Atma-sphere MA2's and Wilson speakers, and I have recent experience (still use) with the MBL 6010D feeding Atma-spheres and Pipedream speakers. The 6010D has tremendous flexibity (even more than the Ref 32) and I beleive it has a rare ability to be detailed, neutral, dynamic and musical all at the same time. The 6010D took over a year to settle in - it was not particularily special prior to that. I believe many of the people that have passed on the 6010D did not let it break-in fully.

Thank you very much for your sharing. What did the MBL sound like without the proper break in? Did it sound bright or anything?
Anybody could comment on the BAT REX especially the bass region?

The MBL is not bright even on break-in - it is full and dynmamic from the start - just sounds perhaps a bit slow compared to an Atma-sphere MP1 for example. After complete break-in it becomes rare as I mentioned above.
