So, now receivers are getting really expensive. OK, there is a five year warranty, but if it blows up just after warranty, that is $1000.00 per year pretty close.
As usual 11 pretty small amp boards inside.
So now the AVP route is really competitive.
Marantz 7706. $3199.00
Monolith 3 channel amps X 2. $700.00
Monolith 5 channel amp. $415.00
Total: - $4314.00
Cinema 30. $4500.00
That is if you must have 11 channels. If you want less then price goes down accordingly. You can add as you want, or funds permit.
The AVP plus power amps, is far more likely to be more durable. It is the much better deal by far, and each unit won't weigh over 40 lb.
