Dear audiophiles, I'm considering upgrading my pair of Dynaudio Audience 120 speakers to mammoth tower speakers, and the two options I'm currently considering, after so much research, are the PSB Stratus GOLDi and the Thiel CS3.6. The PSB is new, the Thiel, much obviously, is used. Anyway, one more info I should add is that the Thiel received an upgrade by the former owner, with crossovers supplied by Thiel itself, and it's supposed to have improved the speakers by $3000 worth, some say. I'm looking for deep and extended bass extention, and an at least average midrange. What would be the choice to make? My current equipment is Mccormack TLC-1, Mccormack DNA-0.5, Adcom GCD-750 and the Dynaudios. I was planning to acquire a Rel subwoofer, but I decided to upgrade to towers, so I eliminated the subwoofer off my list. Thanks to those who help and read.
