I have the sphinx v2 and some Dali Zensor 1 speakers and I think they are a great combo I would think it would pair very well with the Elac's.
I listened with the stock JJ ecc802s tubes for a week and then replaced them with a matched pair of the reissued gold lion ecc 82 and I think that it was an improvement . I am waiting for a matched pair of e82cc mullards NOS and see what that might do
I think you will be very pleased with the sphinx and the Elac's I have bought a lot of high end gear over the years and was really happy (and surprised) by the sound of the sphinx
