Upgrading from Verity Sarastro I to II

Hello my friends,

I own the Sarastro I for the past 1.5 year and I couldnt be more satisfied. Lately I have been thinking of upgrading to Sarastro II. That includes a new tweeter, new internal wiring and a new crossover from mids to the tweeter.

I would be very interested to hear experiences from people that have upgraded their Sarastro (or Lohengrin)!

I am also a bit afraid that sth might go wrong, don't know how much I can trust my dealer's technician.

Thanks in advance,

Mike
