Yep, I angle back my Tannoy Canterbury for the same reason. I used different heights of HRS Nimbus Spacers to get a bigger differential from back spike to front spikes (0.5" in my case). I got the spacers from Ivan.
Tannoys are unique in that you can sit close and not lose coherence. But then you'll need to do the tilting trick or get unwieldy pedestal stands (I think this ruins the aesthetic, no matter the design) to avoid losing too much detail from an off-axis tweeter. And now with a close seating, tilting up, and a healthy amount of toe-in, you'll get amazing dynamics and a solid lifelike image for a very immersive experience, but you'll also need to pair appropriately with upstream gear that won't kill you ears with treble energy from the horn!
