HK is ok, not overly powerful. I bought a Anthem MCA50 last week and made a big difference.
but overall it is good for the price.
Yes, if it was real wood then probably is reasonable, but that is Boston vinyl. And for $150 more can get a 5 yr warranty at Axiom. I think that's the better deal.
The M2's are older haven't really used them
