I am VERY slow to upgrade equipment. My old stuff has to be broken or deficient in some way, or a crazy deal comes along. So my input of contribution will be severely limited.
I currently run Audiovector QR3, QRC, Energy RVSS for the sides, and Paradigm Phantom V3 towers for the rear speakers. A Martin Logan Dynamo 1100X rounds out the subwoofer duties.
A Marantz SR5012 receiver powers the sides and rear speakers, with a Denon POA-8300 sending RMS 200w to the Audiovector LCR at 4 ohms.
I LOVE the sound coming from the Audiovector. Effortless, full, gorgeous sound with no distortion I have encountered. Most everyone who has auditioned my setup agrees it punches higher than expected.
I got these Audiovector speakers for a crazy price from a dealer buddy of mine. Sadly he got out of the game.
The room these are in is BIG and this setup has no issue filling the space.
