Matt, that's good to hear.........when I did that, I found that the bloody thing got under my skin, and I ended up getting it 6 months after I sent it back, as I missed it every time I put on some music.
I love the presentation with Kef Reference, but they look a bit too deep.....though they do have boundary compensation.
You could try the R Series (R500 / R700 [a little too deep]), which are hard to beat for the money......but you would need to check the Bass isn't too much in your room with the 35i (which as you have heard, seems to have an extra octave).
A couple of "off the wall" suggestions (which I haven't heard):
- Diapason Adamentes 111 (a touch too deep)
- GamuT Phi 7
There is also:
- The Spendor A9, or indeed something from the Classic Series (SP1/2R2 or SP2/3R2).
- Kudos Cardea C30
