MC phono stage without transformer?


A newbie question:

I read a lot of 'reservation' about using an external MC step up transformer to increase the gain of an MM phono stage. But as I searched around for MC phono stages, I noticed that a lot of these actually have internal step-up transformers, some of these transformers are exactly the same as what some people used to make their external step-up.

So if transformer is no good, I should really be looking for an MC phono without the tranformer? Do these exist though?

Dear Ron: In my case ( as I already posted on other threads ) I have in deep experiences with Audio Note whole products ( from the Ongaku through speakers, cartridges, SUTs, etc, etc ) due that the distributor here is a close friend of mine. I tested it ( SUTs ) in a whole audio Note system and in my system too.
I already owned almost every single ( top named ) SUT out there including Expressive Technology one.

I can asure you that I know exactly what I'm talking about, please don't have any doubt on the subject.

+++++ " a high class MM tube phono stage and a high performance step up leave the music more intact than any phonostage I know (ASR, ARC, Gryphon...). " +++++

I respect your opinion but like you say " that any phonostage you know ", well you don't know every one and certainly not the best integrated units ( tube or SS ): Phonolinepreamps that are the ones that I reference about quality performance against any SUT.

+++++ " with a lot of highly acclaimed components I heard. For instance the highly regarded ASR Basis exclusive. It was a big disappointment. " +++++

IMHO ( an no quibes against ASR ) " highly regarded " for people that does not care or does not know too much about music, that design is based on op-amps and can't represent a standard to compare with it.

Ron, till you hear the right Phonolinepreamp ( SS or tube one ) you are ( with all respect to you ) " out of base " trying to support the SUTs ( including what you own ) against a well designed active high gain Phonolinepreamp.

Ralph, some other people ( including me ) can do it because we have an in deep experiences about, maybe I'm wrong but at least I already try it.

You have to look to have the opportunity to test it and maybe after that you could think in a different way, you like me have the every day opportunity to learn something about music sound reproduction best quality performances.

Regards and enjoy the music.

Dear Kirk: +++++ " Now I understand and respect a design approach that tolerates a mismatch here to acheive other objectives, but in terms of noise performance for i.e. a 5-ohm phono cartridge, a well-executed transformer/autoformer input topology will ALWAYS perform best. " +++++

I have to disagree with you here because IMHO that depends on the design, that btw we don't tolerate any mismatch at any single level " to achieve other objectives ".

+++++ " NOT deliver their best noise performance when coupled directly to an input stage, especially one that uses JFETs... " +++++

here I agree with you.

+++++ " There is simply too much variation in cartridge design and manufacturing methods to be able to allow EVERY cartrige to work its best with a single type of phono preamp .. " +++++

again it depends on the design.

+++++ " And finally, the biggest issue with improper cartridge loading has very little to do with the transformer or the lack thereof, but with the lack of standards and consistency among cartridge manufacturers... " +++++

that's another reason why the SUTs are not the best way to go.

Dear Raul,

"well you don't know every one and certainly not the best integrated units"

sure my notes are made out of my experiences and I cannot have tried ALL high class units. The mentioned ones have been the ones I was living with for a longer time, but I heard more in different systems (most of my audio friends made the same experiences like me and listening with step up transformers now). Do I heard the best integrated units?...I dont know, but I had one of the most regarded and exclusive solid state phonostages which is said by many people to be clearly above the level of most SS designs, the Gryphon Orestes. As mentioned this one was very good, even slightly "better" in some specific hifi terms such as bass power BUT it doenst let you forget about the technical aspect of music reproduction as my actual set up. My maybe limited experience is enough to make my say that a good transformer is at least not a bigger compromise than a SS unit in general. There might be units like the Atmasphere preamps with high gain tube MC stages which might be a good way of getting rid of the transformers. I just heard the MP3 which was ok but doenst convinced me.

Before getting my actual stuff I was running an all Gryphon SS system never giving a thought about tubes and transformers. But after getting my actual preamp "by accident" I was almost shocked what I was missing all the time. Here we are for sure also on the area of personal taste and I have experience that different people have different ways of listening to music. For me, the more a component lets me forget about hifi, gives sense to music and touch me emotional the better I find component, but I also have made the experience that a lot of people rather focus on things like dynamic, detail, frequency extension instead.
Dear Ron: +++++ " . For me, the more a component lets me forget about hifi, gives sense to music and touch me emotional the better I find component.... " +++++

I share with you totally this statement: that is all about!!!!

Regards and enjoy the music.

Is it any surprise that Atmasphere dislikes MC phono step-up TRANSFORMERS!!!!

But the problems which plague power output transformers hardly exist for tiny signal transformers. Purists will dislike having an extra device in the signal path, but an extra gain stage is the same thing.

We can recite all the theoretical deficiencies of step-up transformers, but the darned things evidently aren't paying attention, and work very well.
