Benz Glider is nice. You can have it as low, medium and high output version. I had the low output version once.

To me the Benzes sounds smooth, they all have a nice flow and kind of "wet" sound. They never sound dry or steril. I have had the Glider L2, L04 and Ruby3 and I liked them all. The Glider is not the warmest of them, but it's still slightly on the warm side. If your after the tightest bass you my choose different.
Mirror, Benz has not changed the ACE yet retail has gone up 350 dollars. Why? It is a giant killer. The differences between my Ace L and Ruby III L are startlingly small. Have you considered a better phono pre? You don't say what you are using. Z,

Thank you guys for all responses. I am using a build by my own pre and turntable. Turntable platter and bearing is from Thorens, motor is DC brushless outboard beltdriven, arm is SME 3009 II. The phono pre is tube based on 12AX7 first tube and 12AT7 second. Step up is tube also 12AX7. I am really happy with the pre. It has also impedance match for different setups. I like the detailed, not clinical liquid sound of Benz. I was also thinking about Shelter as an option, but never compared both. What do you think about Shelter as a cartridge?
Thanks a lot!
