I had read isolated posts during my initial forum searching prior to posting this thread (where I mostly wanted the XiTone comparison). I just read through the full thing, which was really useful, so thanks for recommending.
Here are my main takeaways from the thread:
- Most people seemed very impressed with the quality and performance of the PXMs.
- There was an issue with digital distortion that was verified by EV and they repaired any units experiencing it. They have since fixed this issue and any production units should no longer demonstrate the distortion.
- Some people were doing some custom EQ adjustments, but it sounds like the consensus is that the Monitor 2 is pretty flat and is pretty usable as is. Some people seemed to prefer the Monitor 1 setting. I did see one post of someone using the GuitarCab mode with the cab block off and they seemed to like it.
- Several people did apparently use these as in a backline application. At least a one other had used one of the "non wedge" orientations @Greg Ferguson described in this thread.
- Prices have gone WAY up in the last two years. Glad I was able top get a deal by reaching out to my SW rep.
Bottom line: I'm pretty happy with my decision to go with these and now the waiting begins (I replied to the SW rep's quote that I want to move forward, but the order hasn't actually gone through yet. SW does appear to have stock).
