Joule Electra OPS-1 or 2 MkIII

I am using the OPS-1 Mk3 with an LA-100 mk3.
If you like the sound of the LA-100 (who wouldn't?) you will be happy with the phono stage.
It is NOT as quiet as a solid-state device in high-gain mode(MC) but is silent in low-gain (MM) mode.
If you love fiddling with loading, you would have to have several plug-resistors (Jud will make these for you) and keep switching them around. I had him make 1000 ohm plugs for my Benz Ruby 2 but actually prefer the sound "unloaded" at 47K. Of note, Jud uses a Cardas Heart with this phono stage, which is very similar to a Ruby 2. I'm awaiting delivery on a Ruby 3H, as I feel that the slightly higher output will be beneficial. The OPS does have enough gain for the 0.4mV Ruby 2, but I'd like to see what the extra boost of the 3H will do...

Overall, this is an excellent piece, particularly if you don't feel the need to constantly fiddle with loading.

I have the separate power supply as well.
In response to the loading question, there is no soldering-- you just plug in the resistors into RCA jacks located next to the phono inputs.

As for the Benz "liking" 1K, this was not true in my system, and Jud does not load down his Cardas Heart (makes me wonder if the OPS is "voiced" to favor 47K??)

I was not aware that there was a Mk4. Any word on the cost for an upgrade, Monk?
