Few days ago I've got a 2nd hand Siltech Golden Fire on Ebay. Till now I've used an Oyaide Neo+, which is no slouch. But once the Siltech was connected, a BIG improvement was audible. I'm not a master of hifi-poetry, but much more detailed, transparent and complete is the least I can say. I use it between AudioPC (Dual PC Setup, JRiver Media Center 20 through JPLAY) and a Weiss DAC202. If you got the chance to get one, don't miss it!
