Acoustat upgrade to Spectra 4400


I'm soon upgrading my actual 2+2 panels to Spectra 4400. Any of you has experienced enough to tell what major sonic differences that will make.

Thanks !

They're done and finally in my listening room. All modern and higher quality parts in the interfaces, metal frame.
