Just for the record, the Glider is a low output MC with 0,4 mV output, while the Fidelis is a high output MC, delivering 5,5 mV output according to their website. Apart from a similar price these are likely to be very different systems with different requirements.
I never heard the Fidelis, so it may be the exception to the rule, but most people seem to agree that in general low output MC's sound superior (less coil wire = less moving mass).
Based on my own experience with an older LP (pre 'S' version) I agree with the above description of the Benz sound, which is beguiling as well as forceful. The Jelco by all accounts is a fine arm that will be a good match for the Benz and the Parasound phono amp can easily handle the Glider SL's output. So this would appear to be a very good choice.
