And remember that even if you do do that, then your CD player's DAC is probably the pits to begin with unless you own one of those $3000 players or paid someone $500 to convert your lowly cd player to some new high tech CD DAC.

How about making one conversion from digital to analog on your CD player. Use an analog crossover instead to avoid all those stinkin' back and forth conversions, each one losing more and more of the low level signal.

Try(brand spanking new):

Ashly XR2001
Stereo 3-Way, or Mono 4- or 5-Way Active Electronic Crossover

$539.99

or

Rane:
AC23B Active Crossover, Stereo 2 or 3-Way, Mono 4 or 5-Way $589.00

or

Build it yourself:

Marchland:
XM44-3EZK EZkit, 3-way model. $ 960.0 ($1200 if they build it)

Your choice.

For the models over $600 new, I'm sure you'll hear a difference. Of course you will, when you remember that you paid so much more money, and everyone knows the more you pay the better it is!

The DCX is XLR input, to get the best low noise performance, feed a
preamp signal that is higher than most home audio gear supplies, ie,
home gear is typically 1v preouts. XLR is around 8v preouts. You can optimize the 'gain structure' by feeding it a nice preamp signal from an XLR source, ie Parasound Halo, certain B&K receivers, etc.

It's not mandatory, you can drive it with a 1v source just to get
started and play around, who knows you might like it alot like this.
But there is room to upgrade if you wish.

If you drive a home amp with DCX XLR outputs and your home amp is
RCA input, there is a simple cable mod to lower DCX output gain
so it won't drive your amp too high as it induces more hiss.

Special XLR to RCA cable -6dB output gain;

XLR Pin 1 = Shield ground => one RCA gnd.
XLR Pin 2 = Positive balanced signal => RCA hot
XLR Pin 3 = Negative balanced signal = don't connect

I made my XLR to RCA connectors with a switch that connects pin 3 to pin 1 to allow selection of output gain, normal or -6dB.

This simple cable mod worked nice when I connected the DCX to my
Adcom 555 amp. I got less 'hiss' as gain is reduced.

But now I drive DCX directly into the pro audio amps, XLR to XLR,
no cable mod.

I also use a Roland M1000 mixer [now discontinued], it's the
volume control when using the audio system in digital pathway mode.
This unit allowed to to easily test analog and digital pathways
instantly for quick comparison. This is a nice piece of gear
for $250, I have no idea why Roland discontinued it.

I use a calibrated Apex 220, with preamp, connected to my Powerbook. On my powerbook I use Chris Liscio's great Fuzzmeasure software. current version is 2.0.11.

I usually measure at the listening position rather than 1 meter from the speakers. Line arrays are kind of aways anyhow.

And, of course, while its not currently in my "loop", I have a DOD 2/3 octave constant Q equalizer. Altho, modifying the crossover position and volume can serve as a kind of tone control modification.

Tweaking in this way can be lots of fun and takes lots of time. I'm not currently set up for this, as I'm remodeling the room that my system is in.

You may find, as THylantyr and I have, that you don't need to adjust very much, or that adjusting to YOUR taste is infinitely better than adjusting to some arbitrary assigned frequency response pattern.

After all, all of us humans have different hearing of frequency response across the board with some dips and rises in our perception of sound, regardless of what is actually being presented by speakers or amplifiers.

Right no I have a sinus infection in one ear and my total awareness of my system is vastly different from when I did not.
