With klaus's permission I would be happy to post a range of mods you can do.
If you do them yourself though A: you need, absolutely, to know what you are doin. B: It will void your warranty if you DIY.
I have Odyssey Extreme Mono's with @ $1000 of custom bits in there. For the $$$ they are amazing and come very, very close to the Jadis Ja 200 Mono's which are erm....expensive..Ahem!
So whats in mine? Well lots of expensive stuff.
Some blackgates, Vishay 'nude' S102's, Caddocks, Auricaps, hexfred's, ICW's (caps), ERS, hardwired 1 metre LS cable, Microsorb and acrylic damping, you get the idea. If Klaus say ok I'll post detail's but it's your funeral if you screw up your amp b'cos you only think, you know what your doing. Matt
