    I've seen some pretty good looking mitered wooden boxes for the m125's. Can anyone who has built these share some construction tips? Thanks!

    Do you plan to use the stock SS chassis and add wood to it or fabricate your own from scratch?  What level of tooling do you have access to?

    For scratch build a Front Panel Express rendered top plate (custom machined panels that you design yourself, google them) on a simple wooden frame would be reasonably simple.  Check out Tube Nirvana website for examples.

    Retrofitting a full wood wrap to the stock chassis creates some tolerance issues - to me it's often harder to work around an existing object than build new.  I spun in circles on this dilemma for my build but decided in the end to simply fabricate some wood and metal bits to cover the gaping seams in stock chassis (objectionable to my personal aesthetic sense) rather than attempt a full wrap. Ended up with a look I liked while retaining the retro feel of the stock box.

    Whatever you decide, realize that you likely will need to gain access "under the hood" on occasional basis and design accordingly.  

    Have fun with the project!

    There are some pretty cool finishes you can put on the bare stainless chassis, as well, so don't rule that out before getting carried away with wood.
    PM me and I will send you a couple of pics that Audio Bill on this forum worked up for my M-125s. Might PM Audio Bill yourself for other examples of his fine work.

    Entirely agree with the above. Wood and "modern" electronics are sorta-kinda in the same ballpark as wood-grain plastic, much further apart than Apples and Oranges - much more like socks and fish.
