I Agree Chelillingworth. If I was a skeptic I would even say that the industry has a real interest in folks not doing mods because, if they do not, it keeps things under their control and also keeps the whole thing so unknown and mysterious. If you stop thinking about buying and start thinking tweaking you will find that audio (for the most part) is a mature technology and state secrets are few (at all but the very highest end.) Upgrades, even on pretty good stuff, are painfully obvious and inexpensive.
