I basically started with zilch a number of months back. I now have a pretty fine tube amp, a fine preamp, a dac, and a car full of decent speakers. I'm not seeing changing anything any time soon, and I think that switching around a bunch of tubes/money to get a little bass here or a little treble there is not affordable nor practical. I too, am not embarrassed to add some EQ for the sound I want. Honestly, (for myself) trying audirvana actually took more away from my listening enjoyment than it added, and I could use the $75 bucks elsewhere. It was interesting to try though, and I'm still glad for this discussion.
