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 Axelwahl  (System | Threads | Answers | This Thread) 06-18-09

And I'm beginning to see the value in having a dedicated MC phono preamplifier if LOMC cartridges are preferred. Why bother with 40 dB gain and 47K loading for MM cartridges. The design would, at most, have binding posts to change loading resistors. Being able to change the amplification (gain) would be handy but not necessary if the output voltages of the preferred cartridges were within a fairly close range. Is such a phono preamplifier available?
