From your original post it sounds for all the world that you had a problem with the Synchrony Ones and the M6i and that you're selling both. Then you ask if you should consider the 804Ds after you've apparently already owned 804s with a Creek amp and that seem to have been the source of the whole problem in the first place. Where did THAT come from??? That probably would've been good info to share upfront no? How do the PSBs and M6i even fit into this whole thing? Who is PMC? Seriously? Do you have a browser? Dude, you're a complete mess. I'm outta here.
