Hey there, just looking for some advice, I am stepping up from a Integra dtr 5.3 @ 80 wts per ch to an onkyo tx-nr5007 @ 145 per ch This receiver allows me to bridge or bi-amp my two mains instead of surround rears, which I do not curently use anyway. Should I BI-amp the speakers or bridge the channel for double power? The main reason for the upgrade I really wanted more power for 2 channel stereo music as well as hdmi switching. O and BTW..I am using 2x m60v2 1x vp150 2x qs8 1x ep350 and plan to add a second ep350 very soon.. any help or advice would be great
