ARC REF 3 or MBL 5011 - what is better buy?

I think I need to add more info to my issue/situation. Currently I have Antique Sound Lab Flora (6sn7 tube based) pre-amp. It is a good pre-amp for the money. When playing CDs with small group of instruments (jazz) it produces great soundstage, good imaging, natural timbers. But when playing CD with the large orchestra music, the soundstage remains good , but I strongly feel that all presentation is loosing crispiness, transparency, even so the soundstage remain large. The impression is that somebody put curtains on my speakers. I think this is attributes to the ASL Flora in my system, so that is why I am looking to change/upgrade the pre-amp and ARC REF3 or MBL 5011 are the good candidates. Again, because the possibility of demo is non-existent, I would like to get as much opinions/suggestions as possible.

Glide3, my Flora has a Mundorf caps and I rolled tubes and now have NOS Tung Sol Round plates that considerd one of the best. But even with that, I feel that some transparency missing. Dont get me wrong, it ia a great pre-amp for the moeny, but I think it is has limitations. Does anybody had/have the the chance to listent MBL5011? Based on the couple reviews I found, the MBL5011 is better than ARC REF 3.

Tvad, I hate to say but you are absolutely wrong. All I want to get as much opinions as possible to find a good choice, because for me this is the one of the best options to come up with the more or less of good choice. It does not have to be MBL 5011. As for now, I’m leaning towards ARC REF 3. The only thing that stops me from buying it the opinion of the Audiogon member( Guidocorona ) who seem reviewer for TAS and respected here on the AudioGon. He is stating on several occasions that Jeff Rowland Capri sounds close if not better (for him of course) than ARC REF 3. When I read that $3000 unit sounds as good or better than $10000 unit it make me confused at least and make me to go on another round of evaluations.

Tvad, I agree. I will have to go this road again. Trial and error. Untill I hear it in my system and in my rooom, I will not be able to determine. But still your advise as well as the others is very helpfull. Thank you.
