Great comments above!
I think SET is something to experience. It can be intoxicating, but as mentioned speaker pairing is key and they can be a bit fickle. What speakers are you using?
PL does just about everything really well--design, build, service, reliability, and so on. However, if I had a sonic bone to pick it might be headroom. Everything seemed a bit jammed together sound wise and even though I had the opportunity over 4 years to run it with all types of speakers, everything seemed a bit compressed. Great product though.
Let us know what speakers you have when you have a moment.
