Benz Series 2 advice for an Oracle!


I own an Oracle Delphi Mk V/SME 309 with an EAR 834P. I am currently using a Goldring Eroica H, but I feel that it's time to upgrade the cartridge. Has anyone heard the Series 2? Would a new Glider be close in sound to an old MO9, or should I still consider a new M2? Also, would the benefits of a vdH Frog be lost without a better tonearm? Thanks.

I upgraded about a year ago from a Goldring Eroica H to the Benz M09 and have been very happy. The Glider would have been a nice upgrade, but the MO9 was an order of magnitude better (solid, authoritative bass; smooth, airy highs; more detail & it "draws you further into the music"). Haven't heard the new models but they look like a step in the right direction. (btw, my table is a VPI HW19 III with Sumiko FT-3 arm, Melos phono section)
I also own the Oracle Delphi MKV SE (Granite base, turbo PS.) Graham 2.0/Helikon/Lydian with ARC PH2. I recommend the Lyra Lydian Beta ($600 with trade in) or the Helikon ($1800) with trade in, if cost is not a factor.
Gmorris: I'm wondering where you would buy a Lydian Beta at $600 with trade-in. What are the restrictions for the trade-in cartridge?
Thanks in advance.
