MM Phono Stages With Greater Than 40 dB of Gain?
One of my favorite phono cartridges is the Ortofon MC 2000, I have it with the T2000 SUT. Even so the combined output is still low, and going into my Esoteric E-03 phono stage I have to add a lot of additional gain from the pre amp.
Since I no longer use the Esoteric for direct input of moving coil cartridges I thought I might see if there is a better choice for a MM style phono stage that offers greater gain.
I have looked a bit, but not seen anything jump out. Anyone have run across an excellent MM only phono stage with higher than 40dB of gain?
https://aricaudio.com/products.php?product=TRMMPS I answered your post on AA but will repeat it here. I am having Aric build me a custom 300B amp and later he will build me one of his phono stages with some upgrades including Sowter step up trannies. But in stock form it is MM only with 45 db of gain. I highly recommend Arics work as I’ve owned two of his fabulous amps, listening to one right now.

If you have the bucks, do not ignore Raul’s mention of the new 3180. I own the 3160, and it is superb (and all solid state, in a tube guy’s system). As to the Manley phono stages, the gain stage is a hybrid cascode (transistor on the bottom/tube on top), not purely tube devices, if you want solid state. Mulveling’s suggestion of using a 1:10 SUT into an MC stage, in order to derive enough gain for the MC2000, is interesting. I don’t know of anyone who has ever tried that. The MC2000 has an internal R of 2 ohms and so could theoretically drive a 20 ohm load in voltage mode. To achieve that minimum acceptable load on the cartridge, you would have to use an MC stage with at least a 2000 ohm input resistor. (square of the turns ratio of a 1:10 SUT is 100. 2000 ohms/100 = 20 ohms.) |
