Combing channels from a 3.5mm stereo jack to mono

I found the Beatles recording that always sounded funny on playback (disappearing guitars, weird instrument levels changes). Tried both my Radio Shack stereo to mono adapter, and the PI transformer cable.
Neither cable fixed the weird sound on this recording, which I believe is a bad mp3 file. The Radio Shack cable sounded best, with excellent bass and clarity. The PI cable really sounded bad in comparison. I left my Radio Shack cable in the rest of the night, playing recorded music for a small dinner party we were having. Everything coming through it sounded fantastic.
I'm going to do some additional testing, but my preliminary report is that the PI "DJ" transformer cable is no better than a simple adapter, and perhaps worse.

It sounds like the file might be shifting stuff in and out of phase left relative to right. When in full stereo, you wouldn't notice it so much in the acoustic domain. But when summed electrically, it cancels before it makes it out to the speakers.

We use an iphone into the dl1608 for music to start sound checking and for breaks. I also went the DI box route to get it to one channel :

It works great with left and right inputs down to one XLR out (XLR B channel in mono mode). I also use phantom power so I wanted that separation. However, I'd totally opt for a simpler cable solution if anyone has a less cumbersome suggestion than a DI box.

For what it's worth I've made the hosa type cable. Left and right (tip and ring of the 1/8") to the hot (tip of the 1/4"). Used it for two years now with no problems. I've used iPhones, iPods, etc...
If it works, Wye fix it.
