Soliloquy and Creek?

Mchug as far as watts go, you will have no problems.I'am sure either one of your choices above will make you happy.I own the 6.3s and power them from time to time with a Monarchy sm70 25 wpc.Even this little amp has enough power to make you deaf.If your not stuck on ss look at some cary audio,unico hybrids,or maybe a modified jolida.These speakers work well with just about anything.I even hooked them up to a Soundcraftsmen (MA5002a)500 wpc at 8 ohms and 1000 wpc at 4 ohms.I have to admit it sounded pretty damn good even thou it's not considered an audiophile amp.I found true bliss using a Music Reference RM9 MKII 125 wpc tube amp.But that's my preference yours maybe different.Good luck

I have the 6.3s and they are pretty efficient. I used them with a NAD T770 70wpc receiver when I first got them and that was plenty of power. When I upgraded my amplification, budget concerns had me looking at integrateds. While I never heard the Creek, it was on my list of possibilities. After dealing with Jody at Brooklyn Audio, he convinced me to demo a Redgum integrated. I tried the RGi120s and have never looked back. Others from my list were Plinius, Primare, and Roksan, but the Redgum was exactly what I was looking for.
