In Reply to: Audio Note M2 Balanced preamp posted by mondie on June 08, 2004 at 05:37:40:
I was upgrading from a SP9 MKII and had a AN M2 for a while. It didn't match well with my ARC amp. Too bright and edgy. Although many people love it. And at a friend's home with another amp it sounded great. I now am a believer in system synergy after that. Be sure you demo it in your system - that's where it has to play well with other components.

...which makes them match fine with practically any power amp.Regards

Hi BF,l wont have the ability to run the pre amp to the pwer amp nor DAC to pre amp using balanced connectors as neither the power amp or DAC have balanced connectors. Does this mean that the pre amp will still have low impendace output and be OK?
Thanks for your advice,
Simon
No problem there: what makes it a much better unit is, among other things, their use of some excellent output transformers, which make the unit´s output impedance a very low one.You can use both single ended and balanced outputs, and they both come from these transfos.

Audio Note builds their gear with their stuff in mind - ie; their amp/cd player/turntable/wires/ is designed for their speakers and on their speakers - and vice versa.UHF loved their entry two box cd player but said it wa s smidge hard now and again - but in an all AN system it sure isn't.
Try and hear an all Audio note system - I did and I'm hooked best set-up I've ever heard. So now i'm attempting to build one. I have the speakers and am working backwards. Synergy is a key especially their DAC's which have very high outputs making them totally inapropriate with many amplifiers especially SS amplifiers.
in my talk with "Q" he stressed that while he designs his components to be used as a system, he goes to great lengths to make sure each component will work in the largest variety of systems as well, which increases the design time enormously, and he was quite proud of this.
The DAC ONE.1x signature you heard (told you not to hear it!!!) (the CD 3.1x is the cdt-one transport with DAC ONE.1x signature in one box, which is there best one box player, probably being discontinued as they are making no more transports and the DAC ONE is being replaced) likes a high input impedance (above 50k ohms) for the preamp, but most tube preamps and integrateds have an imput impedance of 100k ohms. My jolida has 100k ohms and even my solid state ARC LS3 has a choice of 50k or 100k ohms. I have a feeling Peter probably doesn't care about solid state systems :)The higher level DAC's don't have the "problem" of the ONE, since they have all had a "filterectomy" as someone below noted. And the DAC.ONE.1x is now discontinued, as it too along with the DAC 1.1x is being replaced with the DAC 1.1x mk ii with a "filterectomy".
My understaning is the M2B works well in any system, but like any component system synergy is key, as you said, and that can't be only done with specs as you know...they have to sound good together.

My AN DAC works spendidly with my Mcintosh preamp/amp.
Just a note about the blanket comment that AN DACs have high outputs. Not all of them do. My 3.1x had good healthy (though not excessive) levels. My 4.1x has a lower output level due to a design change made by PQ for this model. He changed the output tubes (while my unit was being built!) from 5687's to 6463's, and reconfigured the output trannies to accommodate them. The output stage lost some gain in the process. I've tried it with a passive preamp, and nearly full volume is required with amps of lower sensitivity. I'm pretty sure this only applies to DACS with 6463's in the output stage, though.

Hi,Thanks for your post.
l have a heavily modified AN Dac 3 which as you say, has a very high output. My power amp is a hybrid running a pair of EL34's and is rated at 100wpc. it sensitivty is quoted as "0.6v/27kohms for 100wrms into 8 ohms" Not sure if thats good or bad as far as matching with the M2 preamp. Maybe having AN Dac with its high output voltage makes the match between the pre and power amps less critical?
l will email AN and ask their opinion.
Thanks again,
Simon
With the DAC having such high output and the power amp so sensitive, I suggest you looking into good passive controller.Paul Lam
