SUT Advice - Which Ones Are The Best?

I am currently in research mode.  I want to add a SUT to my set-up but I am finding that there is not a lot of information from my local audio shop resources.  It seems that SUTs are outliers in the high end audio world.  
That said, I have read several articles in magazines and the web touting their merits.
Of all the brands out there I am most familiar with Bob's Devices.  Art Dudley wrote many good things about his experiences with Bob's SUTs, and I happen to trust Art (God rest his soul), but I'm wondering if there are others I should consider as well.  Please post your recommendations if you have experience with any SUTs, regardless of brand.
As for my set-up, I have a SME 20/2 turntable, Tri-Planer tone arm, Lyra Kleos cartridge, and KTE LCR Mk5 Phono preamp.  I do not know if I will always use a Kleos cartridge but I do think I will always buy low output MC carts.  I hope to buy something that will work with low output MCs but have some adjustability just in case.
I'd love to hear your recommendations.
@edgewear : The Denon performs very good with any LOMC cartridge impedance I experienced, no single trouble whith that I been aware off. I even listening with the Ortofon MC2000 and due to its extreme low output I only heard some noise but nothing that avoid to listen to that cartridge, yes not confortable at all but other than that cartridge I never had and have any worry about impedance.
I run the MM stage at 47k and at 100k and seems to me that works a little better at 100k.

Could be good for you and everyone to read next approach/explanation about SUTs:

Regards and enjoy the MUSIC NOT DISTORTIONS,

This avoids yet another pitfall of SUT, trying to sell for used something hardly anyone wants to buy new. Take a bath, you will!

That's why I buy used, if I get it at a good price and don't like it for what ever reason I can resell it and not lose anything. A popular or highly rated SUT advertised for a reasonable price usually gets snapped up pretty quickly. It's the odd balls that only work with a very limited cart selection that you need to find a buyer for.


Hey Peter,

I also have a Lyra Kleos and when I was looking for a SUT my research led me to Bob’s Devices.

Bob personally recommended the Sky 30 set to 1:30 with Manley Chinook phonostage

Thats what I went with, great results

Dear @edgewear : "  and not suitable for low impedance cartridges.."

From where or which is or are the reasons for your statement about the AU-1000.

I never read something like this about that SUT and my first hand experiences with told me that's false or at least somewhere misunderstood.

I'm really interested in your comment on.
