I'm not talking about the normal prestige or reference models.
Part 2 in Zanth's interview with John Grado suggested that the HF-1 had, in fact, its own driver but was mum on the details and left it that, so take that for what it's worth.
And by HF-2 in your last post, I presume you're still on about the HF-1? Otherwise I don't think you're going to get a definitive answer for that.
