I was considering upgrading my 5507 to a 5509.
Under no circumstances would I buy the Integra.
I cannot stand the aesthetics and I will not get stuffed into the dealer network.
I like the 5507 pre-pro but it has it's idiosyncrasies.
Turn on THX sub the sound is radically altered.
The 5508 has HDMI quality problems, so I would not buy that either.
Every day, there are fewer boutique dealers. The ones left, want to sell very high priced products.
None of this bothers me, because, when Onkyo start reading the sales spreadsheets, I predict a change in course later this year
