Well, the Elka strings do have their own sound, compared with the Eminent 310. They don't sound all that lush, maybe a bit more brilliant, also because Elka used a slightly different architecture than Eminent/Solina. I happen to have an Elka organ here, a slightly newer and notably smaller model, but it has the strings among the organ stops and a separate Ensemble-like effect with which you can switch between, for instance, a string ensemble (on) and almost Farfisaesque surf/psych strings (off). AFAIK from playing an Eminent 2000 Grand Theatre, Eminent's strings are "ensemble only." On a side note, mid-80s Technics organs had two sorts of string sounds, Italian-style string stops to combine with organ stops on the one hand (which can even be combined with vibrato or a rotary simulation) and, albeit a bit dry-sounding, the probably fattest string ensembles ever on the other hand.
Say, can it be that Jarre played Souvenir Of China on both Elka and Eminent organs since he might still have had that monstrous Artist 707 in his studio in late '81/early '82?

New smallstones sound different from the old ones JMJ used.

Yep, they do. I've got them both. (Okay, the old one needs to be repaired, but oh well.)
And still, there was one new Smallstone on each Eminent during last year's tour.
