Out of curiosity, did you rip the tracks from the CD, or did you hook up the DX90 as DAC to a CD Player?
I just picked up a DENSEN DeMagic CD for $11.00 on eBay and was wondering if I should rip the files or if there is something lost if I don't want to Use the CD...
Even if it turns out to be snake oil, (Even if only to MY ears.) I consider the less than $20 cost to roll the dice worth it.
Thanks for the heads-up!

Yes, i've digital copied the tracks (1:1) as wave 16Bit/44kHz from CD source.
Densen DeMag and the XLO Burn-In are NO snake oil.
Before i "ripp" the source CD, i do demagnetizing the CD by a special Hardware. I use a Furutech RD-1 unit, which is well known to be the best one. ( Not Cheep ) There are also a RD-2 & RD-3 newer devices, but the BIG Magic is only on the rare and older RD-1 devices. They use a different, little softer magnetic field, but it is still very strong. ( You could demagnetize any compass also
CD Demagnetizing was well known at industry CD plants and loved by most audiophiles
( Yeah, YOU!! MSFL 24K gold disc lovers !! ) but in the last 15 years the industry skipped this quality step due to flatten costs and no more CD demagnetizing at production seen anymore.
What a hell... i guess only MSFL, FIM (XRCD) and some others do it.
Numerous reviews with these devices have been done ( i thougt it is snakeoil, too ) and one test nailed it :
The Sound Quality after demagnetizing a disc is bigger then comparing the SQ between a good 2000$ CD player and an 5000$ player.
These devices do demagnetizing the disc with a magnetic field. This field demagnetizes most particles in the material : Nickel, Cobalt, Ferrum in the lacquer and label Print: Color Red = Ferrum Oxide, Color Blue = Cobalt. This technique does also a consitent dispersion of the electrons in the material.
Ken Ishigoru did a commanding Spectral Analysis ( before & after ). Between 1kHz and 5kHz the number of quantity of information increases as a result of demagnetization.
Also CLOVER Lab Sytems Co. USA found out that the total of E22 and of E32 Errors that seriously influence the tone quality will largely decrease.
So, it's best to demagnetize your source CD's before burning to get the lowest error rates as possible !
But as you can hear, after burning or used at a "planted" CD errors are also well reduced.
The "Software" Demagnetizing use a similar technique. There is a magnetic field build up by playing a "special frequency/phase" sweep and steady build down to reduce magnetic "movement" in the device hardware.
This is not so big like a hardware demag but not subtile. ( you have to do it 2 or 3 times the first use ).
The FX of both hardware and software demags are equal: The bass is getting tighter, Voices come with more nature, details are easily to hear and the room is opened and wider. You will love it...
