Dedicated phono-pre for MM only?


Hi All,
the subject of phono-pres, specifically 'adapted' to MM came up in some related postings.

IF, and only if, MMs are much to ones liking --- why spend your buck on some 'halve backed' 60dB plus, MC gain requirement, stage? Why not consider put the $$$ into a TOP 40dB gain stage of either SS or tube?

Raul had more thoughs on the subject as he mentioned before, and might share, why he knows that a TOP MM compared to MC stage circuit requirement might NOT be -one suit fits all-.

There could even be a nice argument to fit a tube gain stage only into an otherwise SS only system!?

Again, the $buck saved on the 20dB plus circuitry could be translated into the BEST circuit for an MM.
I realise, that most such stages were simply fitted inside some older TOP pre-amps, (e.g. Jadis...).
I have not come across a **dedicated** , current 40dB stage neither in nor outside a pre-amp.

Thank you,
Axel

Rockinrobin, I am going to guess that your experience is an overall endorsement of the Reflex. If it were not doing a good job, you might not hear a big difference between the two cartridges. Now you should try the Reflex alone driven by a Grace Ruby, Garrott P77, AKG, AT, B&O, or etc. Let us know how such a combo compares to the Elevator/Kontrapunkt source. Maybe some one of us can lend you one of those gems. (Just kidding...., but it would help the cause.)

Tom, what Jadis preamp did you have in mind? The last top end product from them that I am aware of was the JP80. By now there must be newer models. They have been really quiet in the US market, as in "absent".
Hi, Axel, it makes sense that newcomers to vinyl would benefit from using MM cartridges initially. And having a high quality, affordable (but dedicated) MM phono stage would be something they could continue to use as they upgraded the turntable and other components. The Graham Slee Reflex and Elevator appears to be one option that fits the upgrade path. I don't have the experience to offer an opinion as to whether it's high end or not.

But I think that for many people starting out, committing to MM cartridges due to a specialized phono preamp is not a comfortable decision. I know when I purchased my first "real" phono preamp, I chose one that had a wide range of gain and loading options because I wanted to be able to experiment with different cartridges without having to purchase additional components; i.e., a SUT or headamp.

But it seems (based on the discussions of this thread) that a dedicated MM phono preamp may not be the best design for adding LOMC capabilities, thus requiring a completely different LOMC preamp to get optimal sound. There's no simple (or affordable?) solution. '-)
Hi, Lewm, I didn't offer the Jadis as a reference, Axel mentioned it in his initial post. I checked some prices and one their premium designs (JP80MC) was approaching $20,000 USD. That's when I retracted my suggestion of the Reflex as an example of a high quality dedicated MM stage. Not really fair to compare a $1300 USD phono preamp with one costing more than ten times that. Or maybe it is... '-)

Hi Saudio
EAR 324, a good one in the context of MM - alas it showed some issues with too little head-room in the 20Hz region. Not a lot going on down there mostly, but still.

The 88PB would be more ===> MC targeted I'd guess.
