Hi
to avoid confusion the question is just for people who has actually listened the preamp in question.
I thought it was clear but ...
and i confess ... i ask this question because i am coming from reading again a neverending debate about op-amps.
I am sincerely exhausted of this op-amps yes op-amps not.
I would like just to establish, one for all, that op-amps are not bad per se, but it is the way they are used that matters.
I guess the MBL mentioned is one of the best example of op-amp based line stage.
Is that really so good as i read ?
Thanks a lot for any comment.
Kind regards,

The open loop gain of ONE AD797 opamp is between 14,000 and 20,000. There are 6 per channel in the 6010D.
That's a TON of feedback to end up with a preamp that only has about 15dB of gain.
Hi and thanks a lot for the valuable explanation.
How about the sound ? have you listened to it ?
Thanks again.
Kind regards,

i owned 6010D very recently, apert from the cable sensitiveness the pre amp is mind blowingly good, it supersed the lamm L2.1 and ARC ref 5 with big gap. i only doubted if Gryphon pandora is the MBL 6010D killer.
my 6010D replacing the ML no 326s and mbl5011, and oh my good lord 6010D driveed the 9008A mono and ARC 250se like king.
only problem i faced in the humming. i sould say MBL 6010D is very sesetive on hook up.
still working on my ac power now, so far cant get rid of the hum yet. trying my 11th best. now routing the ac cales with different path with more isolation from power pole. its a real mess in my life at the moment.
but oh the sound of mbl 6010D is in deed breath taking. before i thought dac is the gave changer but now for sure i can say pre amp is the main weekest link in ur rig if u use with a sub par pre amp.
i really dont know how to get rid of the hum but i only know i got to remove no matter how. hope god help me.
please have a demo of 6010D no matter what amp u have, its a killer.
Or, you may want to listen to it and make an opinion for yourself

Beppe...just out of curiosity I bought a Forte Model 2 preamp which has opamps...I might not have bought it had I known the op amps were in the circuitry. Like you I have been biased against op amps in a preamp.
I am very pleasantly surprised at how good this preamp is, opamps and all.
Give the mbl a listen, you may overcome your prejudice in a hurry.
Hi and thanks a lot indeed for the very valuable reply.
Actually i am quite confused by the all debate.
Let me elaborate a little.
1st the preamp in question is unfortunately absolutely beyond my budget
2nd i took it as one of the best sounding (judgement based only on reviews i read) preamp all around.
My point is that if at least one unit very very good sounding built with op-amp in the signal path can be found this changes completely the perspective.
In the sense that op-amps per se are not bad at all.
Maybe tricky to be used correctly but not bad at all.
And also all the critics on the feedback must be taken with a grain of salt.
Thanks again.
Kind regards,

Hi you are right and i would love to have the opportunity.
For now i have to trust people who have been exposed to it.
My point is ... we have to decide.
Or we trust our senses or we trust the scope.
I can even accept the idea that what we see on the scope cannot be related with the sound quality. Fine !
Then ... if a preamp completely full of op-amps sounds very very good to the ear, as i guess is the case but i did not have the opportunity to verify this, well this means that very very good sound can be obtained by op-amps.
So the conclusion would be, very important for me, that op-amps are not bad per se ... but it is important how op-amps are used.
I see some prejudices versus op-amps.
Maybe because cheap cannot be good ?
Yes i will try to listen to it but it is not that common.
I will have to go to the next audio show.
Thanks again.
Kind regards,

At Axpona last year the best sounding room that I was able to visit was using a vintage(their term) 6010 for a preamp. If it can sound that good with master tape based playback and modern mbl amps and speakers, I would think it would not be the weak link in any system. I have only heard that preamp in a total mbl set-up, but I think it's good piece.

Hi and thank you sincerely indeed.
This is indeed the kind of answer i was expecting.
I am perfectly aware of the fact that the MBL preamp is not just a bunch of op-amps ... its construction must be excellent in any part.
However on audiophile terms it should not sound that good with all those op-amps.
I would be extremely curious to see at the schematic of that preamp.
Extremely. To see how they managed.
Thank you again for your extremely valuable answer.
Kind regards,
