PL makes great quality good sounding amps. I owned one.
Pros
--Superb customer service
--Excellent build quality (almost in the top tier)
--Easy to operate, great features, and reliability
--Some of the best remote controls in the business!
--Can run a variety of different tubes, making it versatile.
Cons
--Weight. But weight means quality, right?
--Looks. My subjective view. I was never jazzed about their vanilla looks.
--Not the last word (subjectively) in emotion.
--Lots of competition
There's not doubt in my mind that the products are built like tanks and to last nearly a lifetime. There maybe a mojo factor missing to the sound and sonic picture (again, my own silly subjective view that you should take with a 1/2 grain of salt).
Others are spot on when they say this is a great place to start.
