Ah Mike. I hate to burst your bubble with that but my 16/44wav files play perfectly, no popping! But, if that is the case with yours then FLAC all the way is what I would do. One thing. Would you try converting with XLD and see if that makes a difference.
I remember once doing a wav file I converted with iTunes from CD and re-doing that itunes wav file with XLD, I have no idea why but the sound quality was better. It's like XLD cleaned up the iTunes rip! Just have a go with one of your power amp rips in wav and convert it to wav with XLD and see what happens.. If anything, I have not used power amp as i have a Mac.
Likewise when I rip a CD with XLD I usually get a 1mb bigger file than the same CD ripped with iTunes!!

Oh, that just kills me! I've corrected my post, above! I don't get it, but I'd rather use FLAC than WAV, just for the compression benefits, so I don't think I will invest another minute of my time trying to get WAVs to play without popping between tracks. It will just have to remain an undocumented mystery, as with much of the HM-801.
Now, I'm turning my attentions to finding a way to increase play time away from AC outlets, without having to purchase and carry multiple HM-801 batteries at $80 each. The "mysterious," proprietary, polarized, double-barreled power connector must be replicated if we're to make use of an external battery pack such as the Anker Astro 3 (which can output 9V DC at more than the required 0.8 Amp current provided by the AC adapter).
Interestingly, I've measured 9.21VDC at one of the two power connectors and 9.38VDC at the other, with both of them showing tip positive (+) and thus, barrel negative (-). This suggests that one need only supply two 3.5mm (O.D.) x 1.35mm (I.D.) connectors with 9V DC (tip positive) to replicate the AC adapter. But I haven't tested this, so (readers beware), proceed at your own risk.
The odd thing about my measurements is this: If both barrels are 9VDC tip positive, why is the adapter's connector polarized? There are only two possibilities: It's absolutely necessary -or- it's not. (Duh!)
Pursuing a confirmation of the first possibility, I measured the voltage across the two barrels... Surprise! I got the following results, which I'm still pondering....
My conjecture: There would be no need to polarize the connector (to prevent sticking it in upside down) if they were pulling power from each of the two prongs, independently. No, the connector is (most likely) polarized because they pull power for one circuit from the two barrels and power for the other circuit from the two tips (as shown in the bottom half of my graphic.)
