If you don't need high volumes and or a large room to fill with sound:
1) Amp: $350
2) Pre-amp; Volume pot ~$20.00
3) CDP: $500
4) Monitor speakers: $500
5) Tuner $300
6) Wires, etc. $80.00
TOTAL: $1,750.00
Of course, YMMV.
Also if you get into tubes, vinyl, or have a big room to fill with bass flat to 20hz that number could be $10,000 easy.
