I just upgraded 2 sets of speakers here with the newly discovered Sonicap Gen I on the tweeter circuits. Wow, what a difference! Especially with the old dull sounding, Infinity reference 2000.2 bookshelfs I picked up on Craigslist for $35. These speakers woke up and the difference was dramatic in every way. Dynamics, separation, detail.... I'm hooked and want to start tearing into my main system speakers. ....show less | |
