Opinions on the DS audio optical cart

One of my local audio dealers sells new and used albums. They also let you demo the used albums before purchasing. Today they let me use the "Big" room to check out my selections. The setup was a VAC preamp w/a VAC amp. Speakers the Wilson Alexx , and the Acoustic Signature Asconda w/the DS Audio optical cart. Standard phono's don't work w/the DS so you have to use the DS phono which activates the cart. Sound at the top end was hot and the overall sound seemed to lack a full body sound. Also seemed to pick up surface noise. In the past they had this same setup w/a Dynavector TE Kaitora and a Sutherland double stack phono. Excellent sound. Happy to hear other opinions. I know this cart has received rave reviews but not my cup of tea. Also if you have a top of the line phono it goes in the closet because it won't work w/the optical cart.
