HI,Wolf.I do not know much about the model 55.But forte was a little bit less expensive amp made, by threshold.The most important fact is are you happy with your purchase.If the forte sounds any where near as good as threshold you have made a good purchase.
Forte Model 55 Amp
Anybody know anything about this amp? I did email Jon Soderberg and am waiting for his reply...but I think it's interesting that I can find almost nothing anywhere about this particular model other than the bluebook listing here. FYI in my somewhat modest system the amp sounds GREAT...(Adcom GFP 715, Silverline Preludes, REL Q150E sub). Anything leading me to a detailed list of specs or whatever would be greatly appreciated. Thanks.
