Proteus compared to MSL ultra eminent ex

Thank you yeti42. I am using a VPI Fatboy gimbal 12" arm on VPI HW40 turntable. 

Thanks miljostyn.

Thanks Raul. I think the Colibri has a much higher internal impedance, doesn't it? 

Thanks edgewear. I appreciate your comments. The Proteus really is great. For my system, a cartridge with the type of specs I noted, like the Proteus, seems to work well. Hence my interest in MSL.

What cartridges do you like in terms of having better "dynamic jump and mid bass slam"?

Thanks edgewear.

Thanks Vuckovic and Montesquieu. Very helpful info. I love my Proteus, but getting another very similar sounding cartridge may not be the way to go. Not sure. But the specs and descriptions of sound that I've read for the Ultra Eminent EX are very compelling.

Thanks vusi. That's really helpful information. I appreciate it. I have not really looked at Benz, thought they were difficult to find?

Edgewear, thanks for the follow up. I am leaning toward the MSL Ultra Eminent...

jperry, thanks for the tip about Ikeda. I'll check them out.

bukanona, thanks also for your comments...why have you limited yourself to cartridges with internal impedance below 3 ohms? Thanks.

Thanks bukanona. That's very helpful.

Thanks guys. Interesting discussion. I would love to hear more comments, especially from anyone who has had the opportunity to actually hear the Proteus and the ultra eminent EX in some sort of comparison. I realize that will be tough but I welcome any and all opinions. Thanks again.

Thanks miljostyn. Really appreciate your perspective. I have never heard a clear audio cartridge or the Winfeld. I think seven ohm internal impedance is probably higher than I want if I do wind up changing the cartridge. From my reading, it seems like the my sonic labs or the air tight cartridges are among the best options for very low internal impedance with a reasonable output.

Thanks for your perspective as well, lewm.

interesting. I will have to read about the Audiocraft. I don't know anything about it. Appreciate the info!

Raul, the reason I'm looking for a very low impedance cartridge has to do with a noise issue. After I rearranged my equipment on a new, custom rack system that lowered the overall height of the components, my higher internal impedance (10-11 ohm) cart picks up some sort of high frequency noise that, while very faint and intermittent, bothers me. It didn't do so on the old rack with the turntable higher up and farther away from the other components (amp in particular). My Proteus, with 1 ohm internal impedance, remained dead silent--no noise, and still sounds awesome. I have done every troubleshooting maneuver and rearrangement short of raising the system back to its previous height. I want to keep the arrangement I have now. My options seem to be : 1) revert to old setup with higher rack between speakers; 2) move turntable and phono stage to side wall, requiring 4-5 m long interconnects and new power arrangement; 3) sell the higher internal impedance cart and buy another very low internal impedance cart like the Proteus that rejects noise better. 
Because I find slightly better imaging and soundstage with the lower height setup, and because I don't want to spend a ton on very long interconnects and installing another dedicated circuit to move the table and phono stage to the sidewall, I think I'd rather get a different cartridge to alternate with my Proteus when I want a change. I have other carts on other turntables, but this is my main system and I want a great cartridge for it.

 Thanks!

Thanks Raul. I don't think I followed all of your comments, but I definitely do get the point that this choice to go with lower impedance cartridges would eliminate  a lot of others from consideration. However for this set up what I want is two excellent cartridges that I can alternate from time to time. I am not the type who is going to buy lots of different cartridges to try every so often. I love my system, it's very stable, and I love the Proteus that I already have. I just want a cartridge that will work regardless of the way I have things set up and make beautiful music without my being distracted by various noise and other problems. I know, that's what everybody wants.
