What percentage do you spend on each component?

Oh,yeah. I forgot to put in power conditioning. I have a large solar power generation system that keeps a large battery bank charged for all my daily uses, including my audio system. None of my stuff runs off of street power, since I'm not hooked up to the power pole. I provide all my own electricity. My entire audio system, except the CD player, runs off 12vdc batteries. No grunge, no RF, no ripple, no step-down transformers, no rectifiers, and no power failures. Just flat clean DC power. And no power bill, either.

Does this count toward my audio system budget percentage? If so, I am pushing 50% for power conditioning, and my system cost just jumped to about $25K.

I did not pre-calculate a budget, but here is what I've got:

TT/arm/cart - 31%(DIY kit)
CD player - 13%
preamp - 15%(heavily DIY modded)
amp - 25%
speakers - 14%(DIY)
cables - 1% DIY)
room treatments - 1% (DIY)

Obviously, I am heavy into the front end, which reflects my philosophy on system design. The rest is pretty balanced. But, my speakers are DIY, which would definitely cost alot more if they were factory made. Same with the cables and room treatments. The TT is a Teres kit, which saved me a bundle compared to the performance level it provides. My total system cost is about $12k. It would have been much higher without DIY, and I am very happy with the results of my DIY performance at lower cost.I estimate that if I had to buy equivalent performing products that I did not DIY, the system cost would have been close to $24k(double).

Nobody, including me, has included the cost of their music in the budget. Interesting.
