Thinking about ordering to use with my Soundsmith retipped Ortofon MC-20. Any opinions on this combo?

Follow Ups:
There are multiple variants of the MC 20. If it's an MC 20 Super or MC 20 Super Mk II you might be ok although you're probably still a bit light on gain.
If it's the original MC 20 (with blue body) or MC 20 Mk II those both have very low output and the Bugle won't have a chance in hell of working with them without some further help.
60db is not enough for a low output MC? Really?
-Wendell
Not if it has .07 or .09 mV output like the original MC 20 or MC 20 Mk II.
Do you have the original MC 20 (blue body) or MC 20 MK II or do you have a Super or Supreme variant with higher output?
It's an original rebuilt by Soundsmith. I've never had a problem driving low output mc cartridges with 60db. It would not be enough for very low output cartridges
-Wendell
It will work. If it's really only 70uVrms while playing at reference level, 60dB gain would only bring you to ~22% of nominal on a standard -10dBV input. Many pieces of gear will not perform optimally when driven this way.

Mine was quiet using a Dyna 20XL and Benz L2. It could be my ears or rig at fault but I had no issues. Personally I prefer using a SUT and 47K with LOMC. Tonal preference.
I also have a Piccolo 2 as well which is an option if you want to leave it at 40 gain levels.
You could also solder in sockets and just insert the resistor of choice for each cartridge. Not optimum perhaps but very flexible without all the connections of a switch. Quality will depend on implementation and the socket choice. Jim would probably advise against this.
The customer is then charged what he is likely to stand. ...
better off with the 40 db version and a trany.

Good to know. The 40db unit is very quiet with my Ortofon ST-72 step-up.

It outperforms its price, that's for sure. You'd have to spend a lot more to beat it. I think the noise floor would be quite tolerable. A better linear regulated 24V power supply would be a nice upgrade I bet. The supplied switcher is going to make noise. It's interesting how they have power supply parts on the board the get the plus/minus voltages needed. I think the old one used two 9V batteries for plus and minus 9V.

I asked Jim if he could recommend an upgraded power supply and provide adjustable loading. He is answer was an emphatic no. :-)

uncharacteristically gave a one-word answer . . . NO!

Based on the responses here I suppose I will pass on the 60db model and stay with what I have. It sounds way better than it should for what I have invested. I am going to think about an upgraded power supply.
-Wendell
Well I can understand the adjustable loading. You have to install certain resistor values on the board depending on if you want 40, 50 or 60dB gain. Installing all three and a switch would require a lot of work.Switching to a linear supply especially as inexpensively as the one I linked is a good idea just from the aspect of eliminating a noisy switching power supply from the environment even if the linear supply does not benefit the phono pre circuit.
