@DRUBIN, I had the Dyn special 40 and upgraded to the Heritage special. Using my Passlab 250, I did not like the Heritage and ended up selling them and purchasing another pair of special 40's. In fact the person I purchased the Heritage from, took my dyn 40's in trade. Not saying its a bad-sounding speaker, but for my ears it was too bright. The dyn 40 is one of my favorite speakers in my collection. My PS audio F5 will outclass it mainly because of the ribbon tweeter. I have a pair of Buchardt
E50's on order so I will see how they compare. Regardless the Dyns will stay in my collection.
