I was able to transcode all the .wav files to AIFF. Now I must re-import them into iTunes. I also have backup copies of all the songs in both formats (I only have about 6,000 songs and a lot of harddrive space).
Looks like my next audio adventure will be trying to replicate the Bryston BDP-1's (digital player that plays files from an attached harddrive) sound quality for far less cash. The Auraliti PK100 provides automatic bit perfect playback of music from 16/44.1 kHz through 24/192 kHz and costs less than $800. My brother is a computer wonk, so hopefully he can build me one for less that uses the same or better components.
Aside, listened to some old Audioquest CD's last night and they sounded excellent. To bad all CD's don't sound that good.

That looks good from 100Hz up, which tells me the flanking subs are setup correctly. I do think you might benefit from adding one or two more distant subs to smooth the lowest modes. You could fill in that 60Hz notch, for example. That would make the 40-50Hz region sound less pronounced, because the bass would be more uniform, overall.
You'll notice the difference between the peaks and valleys below 100Hz is around 15dB. This is typical of room modes that aren't well damped. The peaks and dips above 100Hz would also be this large without your flanking subs filling them in. The flanking subs reduce the ripple by about half. Add another sub or two placed further away and you can expect the same sort of smoothing below 100Hz as the flanking subs provide above 100Hz.

One or two more subs, do I look like a sub junkie to you!
Okay, maybe I could become one. When I return to the US (nearly 1 year complete, 1 more to go) I am thinking about building true 3 Pi sub enclosures (vice 16" sealed cubes) for my flanking subs (set to the outside of the 4 Pi's), a JBL STX828S sub (dual 18" 2242 H drivers, 37 Hz 120 Hz +/- 3 dB), and a DIY 18" LLT (large, low tune) sub tuned to 11 Hz for the bottom (models at >110 dB at 10 Hz, 1200 W input, slightly under Xmax).
With proper distribution this combination should address the room modes and be flat from below 20 Hz to LPF.
If not, I could always add more

I am running http://www.asus.com/Multimedia/Audio_Cards/Xonar_Essence_STX/
for my sound card with RCA cables straight from my PC to my pre-amp and play mostly .flac files. It is slightly compressed but the sound quality is very impressive.
Not sure if that helps you at all, but good luck.

Thanks I will give it a shot. I ordered the Audioengine W-3 wireless transmitter (cd quality DAC, not high res) to send from my computer to the stereo without using the internet (which is not so good here in Cambodia) or wires (which are fine here, but I don't want them running across the room).
