Probably the same places that sell CD demagnetizers.
Also, I have an O2 vs TOTL moment to share.
Recently I got a chance to compare my O2 and ODAC to an Eddie Current Balancing Act's singled ended output fed by this with some HD800s and preferred them on my O2 and ODAC. The BA added a little sweetness to the treble and gave it a little less edge It also had some reverb like effect going on that seemed to make the soundstage a little bigger. On the O2 the bass was tighter, imaging was sharper, and kept better separation during during busy passages. The treble was a little sharper but I think creatology would probably fix it.
I've heard that the tubes the BA had weren't a good match for the HD800, some questioned the idea of adding a tube output stage to a player that's already pretty good by itself, YMMV and all that...
We ran the O2 versus the BA many times and I've never heard a reverb effect making the SS bigger on the BA. The HF heater actually does increase space but not by adding reverb. I think you were hearing the tubes in the CD player while not hearing it from the O2. I agree w/ the bass and imaging part though. In that case try a Super 7 next time if you can. If you can make it to the LA meet I plan on running 3 different Super 7s next to each other in 3 different configurations.
Edit - That looks like a 4 stack of clarity caps in the CD player too, hmm...that thing is beginning to scare me.
Did you try the BA using the ODAC?
