Does Anyone Use a Portable CD Player as Their Source?


Just curious to know if anyone has tried using a portable CD player running off AA batteries as their source? I’m doing this right now along with a remote controlled stepped attenuator preamp going into a 400 W/ch amp and I’ve got to say I’m pretty blown away by how natural everything is sounding. Listening fatigue is virtually non-existent, instruments and voices sound natural, and piano notes don’t jump around the room. Obviously it has some weaknesses as you can only expect so much out of a cheap consumer device that wasn’t designed specifically for audiophiles, but it’s impressive nonetheless. 
I think it really boils down to it’s simplistic circuitry and having everything on a single board. For example, there is no:
-grid connection
-transformer
-AC-DC power supply
-power cables
-electrical system noise 
-Etc.

If you haven’t tried this, I encourage you to give it a shot and see what you hear. It has been a fun experience for me.

I dug up a battery powered CD player and listened to it . . . during last month's big freeze in Texas - and the attendant power outage.  So they have their niche, and given the circumstances I was happy to have one.
SONY D-421SP.

I used it for some time via Line Out a couple of years ago. It served the purpose, but results were nothing to write home about.

Another issue is egonomics. Small buttons, no remote (virtually never), hanging at the end of connecting cord.
