Honestly, I have no idea what Bobby said. I've already decided to keep the speakers, at least for awhile. Fritz at Fritz speakers told me that the improvement I would get with his speakers (similar price range for Merlins new) may not be a very discernible difference. Also, almost everything I've read seems to suggest Merlin TSMs perform at their best with tubes. Not poo booing your suggestion, just telling you what I have read. I've nothing against solid state at all. Any response to this? Thanks.
