Benz Ace vs Ortofon Rondo

I would lean more towards a Denon DL-103R than to either of these. Don't know your tonearm though.

I assume you have the 9cc arm and that is too light for a Denon DL-103R so that should be out of the running.

I haven't compared those two carts (have heard a Benz Ace) but what is it that you do not like about the Blue Point No. 2? In my opinion it is a very good cart. If you haven't given it a chance to break in you will not hear the best from it. Also, what VTF are you running it at?

Just a note: checked your previous thread and noticed you have only had the TT for a month - unless the cart has had heavy use it is not broken in yet, it needs at least 50 hours and better yet 75. Also, take the money you were going to spend on a new cart and get a good outboard phono amp. IMO it will make a bigger difference to the sound than changing out the cart.
