can you give more specs on your speakers? what's the sensitivity? impedance?
Definitive Technology BP7006's (towers with built in sub's)
8 ohm
200 watts max
Onkyo Grand Integra M-508 is for sale.
Mark Levinson ML9 is for sale.
(talked to both owners)
And as for big box stores:
I've also narrowed it down to a new/refurbished Arcam AVR400 for integrated receivers and possibly Marantz 7005 (or close). $1000 for the $2500 Arcam sounds good. The Marantz options would save $2-300.
There are also some cheaper B&K ST2140 amps for sale locally. A McIntosh amp sold recently for under $1,000, didn't last long.
