I also want to recommend the F7 amp, I now have the Wyred 4 sound STP-SE (stage 2 upgrades) preamp and it is really showing this amp off to its best I feel. My Manley Shrimp (tube) also did a fine job, but the amp has such character I liked the idea of not coloring it, hence the (mostly) no-gain buffer. I use Devore super 8s (please forgive me!), though Louis graciously lent me Omegas to try some time ago when I had Red Wine Audio gear, so I know how good they are.
