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

Well Lewm,
thank you for sharing. Now with 3 'tables why not give a NICE MM a try and let us hear what would be your finding.

It could be most interesting (didn't say rewarding... :-) to have another take by someone of your long standing anlogue background. If only to have some more prespective, and for under $1000 it be just as well :-)
Thanks,
Axel

Hi Axel and Lew. I'll go out on a limb and recommend a unit I've not yet heard. One of my local audio buddies (he introduced me to Raul, literally during a visit) who has since built up a stable of at least two dozen MM carts uses a phono stage from Emotive Audio. Apparently the good folks at EA, while normally designing tube gear, feel nothing they've found betters this ss design. I hope to hear it for myself soon as my friend is a very observant listener.

Since the JLTi was mentioned, I'm using one with a custom, fully regulated power supply. It offers selectable 40/60 dB output so is not a dedicated unit but has beat out a few other ss and tube phono units with my Grado Reference.

Your findings should be interesting so I'll keep watch of this thread.

Hi Pryso, This is the second time someone has recommended EA to me. Since you are a more credible source than the other person, I will look into it. I did also think about buying a basic JLTi, second hand, and upgrading the power supply myself. Did you build the custom supply for yours? If not, do you have a schematic?

Curses, I just lost out on an auction for an AKG P8ES cartridge on eBay. Why? Because I was so busy all day I forgot to increase my bid, which I knew would not withstand the assault of last-minute bidders. i do have my old Grado TLZ, and that is the first MM I will try in the new era. What about the AT150mlx? That seems to be liked by most.

The two that come to mind for me are the K&K Audio kit and the original Hagerman Trumpet.

Hi Lew. I can solder but have no ability to design circuits.

I previously used a Threshold FET-10 (a unit I still endorse and a great bargain at $7-800) and an audio buddy built a regulated power supply for that for me. I changed to the JLTi mainly because it offers external gain and loading selection, but when he converted the RPS to my JLTi (which started life with a wall-wart), it offered some audible benefits as well. So yes it is custom and no I don't have a schematic.

The same friend with the EA phono stage just picked up an AT 170(something), one high on Raul's list.

Good luck in finding a few of these "hidden gems".
