Hi borg -
Glad that you and Louis had a chance to e speak. I have had Omegas in at least one of my systems for almost 15 years. I am using the Super 7 monitors now.
Two observations. The larger driver/ cabinet makes a very noticeable positive difference. For all the quickness that the RS5 driver brings to the table, the larger drivers truly flesh out the sound and allow you to play louder, so any loss in quickness is not that big a deal anymore. Also, the larger drivers are not that susceptible to 'honking' at certain frequencies.
You may find yourself swapping in different amplifiers and experimenting. I am using a Rega Brio R now with my Super 7s and I like the pairing. In the past, I have paired Omegas with tubes (Prima Luna PL1) and vintage receivers (Marantz 2240) and current day receivers (Outlaw RR2150) and current day amplifiers (NAD 320BEE). I probably liked the tube pairing best, though the Rega is quite good.
Good luck & congrats on the purchase.
Rich
