DACs: Airport Express vs waveterminal vs mini-dac

I know this is impossible to quantify, but with a good stereo system (Cayin TA30 tube integrated amp & Green Mountain Audio Europa speakers), what's the magnitude of difference using the following dacs?

Airport Express (I already have the AX, and can connect it to the integrated amp with RCA's [analog])

Waveterminal U24: computer to USB to waveterminal to amp (waveterminal does the DA conversion)

Inexpensive DAC like ART DIO with waveterminal: computer to USB to waveterminal to ART DIO to amp (ART DIO does DA conversion)

Apogee mini-dac: computer to USB to mini-dac to amp

Other?

What's the best bang for the buck?

Kenn39: I am aware of the Waveterminal as a device than can take USB out of the computer and convert it into S/PDIF or coaxial. What others are there and are some better than others?

Pardales: I was referring to the various stock models from M-Audio and Edirol, and mod versions from Empirical and Redwine. Many have been mentioned earlier in this thread.

I have not tried any other than the stock M-Audio Transit. Pairing with a Benchmark DAC1, I was overjoyed when using Secret Rabbit Code upsampler with Foobar2000. I think Waveterminal does not have the option to output 24/96.

Reading the marketing info on the mods, I think they have the potential to be better. I may look into them seriously in the future. At this point, I am just enjoying music.

Racerxnet - forget the sound card. Use an external converter with it's own power supply, or a USB DAC.

Audioengr:

I am using an external DAC. I bought the Music Fidelity TriVista 21 DAC for this purpose. I still need bit perfect output from the sound card at 44.1 Khz. I have reverse enginneered the driver for the Realtek 850 with IDA Pro so that I get the correct sample rate. It would have been easier to buy a new card, but would not be a challenge!

The DAC I bought was quite expensive at the time it was released. Sounds very good to me with my current set-up.

I've played around with using the airport express and then a TOSlink to a dac (Musical Fidelity) and into the preamp. Preamp is GamuT, amps Electrocompaniet, speakers Harbeth Monitor 30s. I cannot tell the difference between this and a $2,000 cd player.
