System edited: Replaced Cambridge that was doing pre duties with a Quicksilver linestage. Improvements are remarkable right off the bat, I knew the Cambridge was holding my system back but I had no idea how much until now.
System edited: Removed Grant Fidelity Tube Buffer from system. Will evetually introduce tubes again with a new pre. Hooked up W4S monos and first impressions are very positive. They seem to have a great "grip" on the panels, bass is much improved. Damping factor is more than quadruple my previous amp.
I am on the hunt for a new pre, probably will go tube based. First I have to replace my amp, I will go class D due to the fact that I need high power in a small enclosure that will fit in my cabinet and not overheat. I am not sure about the Cambridge as a Preamp either, I don't feel I get quite the volume I should. My Crown's input impedance is 10k ohms which is pretty low. I have yet to find the specs for the pre-out impedance of the Cambridge but I imagine there is a mismatch between the two. I knew there would be issues with my electronics going in though. I bought my speakers knowing I would build a system around them while using my existing gear in the meantime.
Thanks for the kind words Mjcmt. The Magnepans do fit in quite well with my(wife's) decor, although I did buy them for their sound as well having auditioned them first. They are quite the conversation piece, most people have never seen a flat panel speaker and are always eager to listen. It is a good way to introduce people to higher fi.
System edited: Hooked some powered computer speakers directly up to my cable reciever, no longer need to use the Cambridge to power my seperate TV speakers. This means I can upgrade in the near future to a dedicated pre, probably something tube based.
Thanks for the reply, I do pull them out when listening and toe them in a bit. I have the same boundry gain issue with the speaker closest to the wall. I have been researching some DIY treatments that I can put up and take down when not using the system but have yet to come up with anything.
