I have to agree with MikeB’s comments. Additionally, I would add that the various sizes SL makes is also a factor. The smaller size panels are less efficient and require more power than the larger ones. The back plates have improved over the years- the latest generation of back plate, previously an upgrade, is now standard on most models, and provides a significant improvement over previous generations. The room in which the panels are placed is a major factor. Cubic footage (not just square footage) of the room vs. panel size is very important.
I have 2 systems, one with the U-545PXs, another with the U-1PX, both driven with Pass Labs, but different models. The difference must be heard to appreciate. SLOG members are welcome to visit to hear for themselves and learn more.
