I think Plato may be a little confused, or I do not understand what he is saying. Spectra's include 33's and 3300's, Mdl. 3's are not spectras. I have Mdl. 3's and 3300's. I am using a slightly modified Moscode 600 amp to drive them. I intend to upgrade it to a 500 watt a side amp, and believe that will finally satisfy the Acoustats. If you have a contact at Rockford who can get transformers, I am considering bi-amping, but would need 4 more Spectra transformers to do so....
Thanks,
Lou
