These are the worst subject threads:
PL vs whoever.
No doubt the USA Raven is good stuff without hearing it. As a PL owner however, I can say the Dialogue series or newer will easily drive those XT6's. I've heard those and the XT8's extensively when they came out.
You can pick apart and do the Raven vs PL audiophool spec thing, but if you're going to just enjoy listening to music the PL won't disappoint. Of course its a subjective thing, but using the "it's made in China" reasoning is dumb.
YOUR TANNOYS ARE MADE IN CHINA! A good chance the majority of your other gear is also, deny if you choose.
There is plenty of PL praise here and elsewhere. If you can find a dialogue series used, it will do the deed.
