Uli, if you read my earlier post, you'll see I mentioned the special EMM Optimism that AS is producing (or will be producing) it's already posted on their website. If/when it is ready, I'm sure it will be outstanding.
Henryhk, I am using the standard Optimism V2 with my Wadia DAC and transport, and the reproduction is stunning. I wouldn't even consider going to an electrical connection now. Also the IO gel takes the performance a notch higher, and will improve the performance of any fiber optic cable, probably even Toslink.
I can't speak to the performance of the Optimism with the Meitner, or even if it's available yet. But I can tell you one thing: Tom Dzurak of AS puts an extraordinary amount of effort into developing his products. I don't think he'd take the time to develop something specifically for one brand of component, unless he thought it would result in significantly better performance.
BTW, AS glass cables are being used with a number of transport/DAC combos, not just Wadia. They are also the "drug of choice" for some very well known digital recording professionals who are involved with special applications such as HDCD and JVC's XRCD.
