I have not, I rely on 6moons for those comparisons. I have had the F4 and Aleph 30, and prefer this to both. The Shrimp preamp I use is a good match, very low output impedance. There are others too but I agree it takes some looking. Worth the effort though!
First Watt F7 owners, impressions?
Let's discuss speaker and preamp pairings you have found to work the best and why. I love this amp but maybe haven't been able to get the best out of it yet.

- Preamps: DIY Pass B1- great except for dynamic scale and deep bass, of course with no gain I also had to jack the volume a lot more; Manley Shrimp - better slam, more density, 12db gain helps a lot overall a better match. Want to try: microZOTL, Pass x-1
- Speakers: Gallo 3.1 - easy to drive though only 88db sensitivity, controlled well by the F7, plenty of tuneful bass, plenty of volume using the Shrimp and impressive soundstage; Devore gibbon 8 - just acquired these and am getting used to them, definitely leaner and less bass but I like the midrange and punch a lot, soundstage is excellent too, and their look and footprint appeals. Want to try: Harbeth monitor, Spatial M4, Zu Soul, all of the speakers Srajan of 6 moons owns!
