I owned 3.5s for many years. Aside from its appetite for midrange drivers, a very good speaker. Without getting into discussions about "accuracy" vs. "euphonics", I can only say that the the 3.5s are a bit sharp and benefit from an amp that can subdue this aspect of the speaker. Many people believe that pro amps are harsh and, for example, slag Bryston because they sell their amps in both markets. You don't mention how much the Meyer amp goes for and, therefore, can only assume that it is priced right. Many companies that sell directly to the end user offer a trial period. If that is the case, I would certainly try this amp and keep a very open mind because you can't believe all the hype you hear or read.
Good luck.
