Yep. I've said this before, and I'll say it again. Master word clock generators are used for syncing different digital devices together. That is why you buy one. This whole phenomenon of buying an expensive clock to improve cheap converters is total marketing B.S.
I own an Isochrone, and I've had a Big Ben as well. Both are great. I haven't done any extensive comparisons between any of these clocks, because honestly, I don't hear night and day differences. Maybe next time I track something I'll do some casual listening tests.
I'm not saying that a really good master clock has no chance of improving cheap converters, but you'll get a vastly bigger improvement by buying some better converters in the first place, or when you can afford them.
But if you need a master word clock to sync your studio (converters/digital console/DAW, etc...), by all means buy one. Just don't be fooled by
marketing trolls. Spend your money on some Myteks. You won't be disappointed.
