proper Tannoy Canterbury room set up

so I have a set of Tannoy Canterbury GR on the way to live in my dedicated 14'X18' music theatre. The system in located on the 14' wall. Previously Quad 988 esl have lived here, which sat out about 4 foot off the front wall and 2 1/2 foot off the sides, with toe in toward center. To start off with, should I position the Tannoy the same? or not? Someone told me that Tannoy is designed to go back-right-up to the front wall - I have not heard this from any other, so I wonder if it is true or not? Would love to get instruction and hear what other Canterbury users are doing with their room layout.
thank you in advance for thoughtful input.

I started out with Viva Auroras. Moved to The LARS Type II with 300B-XLS.

Now use ASR Emitter II Exclusive Version Blue -
Look up for Sumiko setup in the web. It's a very interesting method for positioning your speakers in the room and the results, after some trials and errors, is great. My LS 50s are sound better than ever.
I ran across this post and used some of your ideas here in 2019. Does anyone care to update your previous posts. Using Kensington GR’s with CJ Tube amps (Premier 12’s) I just redid my position of them using the Cardas Speaker placement calculator and it is a completely different experience; in a good way. It opened up the field, has them syncing to my ears in a much more pleasing and holographic way. Unless I am wrong it has made them disappear. Please feel free to update me on your set up including the Sablon speaker cables you felt you might use. 
I upgraded from Canterbury SE to GR, and the latter definitely has more treble energy & extension, which I felt was a bit lacking in the SE (with controls set to "flat") - it’s more balanced, more detailed, and simply a better speaker. I enjoy them more. I didn’t change my speaker positioning or toe-in, and still use the tilting trick, for which I found that HRS Nimbus spacers (mix of 0.8" and 1.3" spacers) look great with the stock feet! I wouldn’t advise mixing the GR with any bright gear, but that’s fine.

I’m somewhat interested in the new super tweeters, but don’t feel like anything is lacking here. I tried the old ST100B/ST200 and felt that they’re just not good enough for the improved GR models.

I really liked my old Kensington SE, so I bet your GR are the bomb, @jahatl513!
