If your whole system costs $40,000....


how much will you invest in CD player with that sum?

I have been wondering my CD section is the weakest link, its around 10% of my system cost. I wonder people who are using some $10k players how much their whole system costs roughly...... Anyone can share their experience in upgrading their CD players?

Frankly I'd sell any high end CDP for whatever you can still get for it (while you can) and put the money into a PC/MAC - DAC based source. CD players are likely going the way of VCR's - there just won't be much of a market for them in five years time. And burn your existing CD collection to lossless PC audio files.
Find a pair of speakers that knock your socks off and then an amp that matches well.

After that, it's downhill all the way.

IMO
1) Speakers

2) amps that match and compliment speakers

3) preamp (choice to compliment 1 & 2)

4) Sources
a) analog source (table and phono preamp)
b) DAC and some server or disc spinner. I wouldn't waste money on a stand alone disc player.

5) Power conditioning (if needed in your area, some don't)

6) Cables (I'm a firm believer in simplier is better cost vs benefit)

7) Tweaks - cleaners, sound deadening, etc....
if i had a 40k system. I would know that i was most likely got hit by lightening. You ask y? Because when I open my wallet and take a dollar out. Washington takes a deep breath and says mmm fresh air...
