Before I post this, let me just say that I consider myself a true audiophile, so the amount spent is justified in my opinion.
That being said, here is my "setup."
Paradigm Studio 100s ~ $2000
Rotel RB-1090 Stereo Power Amplifier ~ $2000
Rotel RC-1090 Stereo Pre-Amplifier ~ $1200
Denon DN-C685 ~ $850
And for when I want to do some headphone listening, I only use one brand of headphone, and that is Grado.
I have the Grado SR-325 ~ $350
My next purchase will probably be Grado's flagship headphone, and that is the Grado RS-1 ~ $750.
