Best Digital Front End Period!

The question is What is the Best Front End Digital Period! Price no object BASED ONLY on what you, have personally listened to, not heard about. Also please give a brief description of your sonic impressions. Ideally you have listened to the piece in YOUR system but sometimes a product is sooooo good that it trancends performance of other products in an unfamiliar system. I have read many threads on specific products but if dough wasn't a criteria and you could own it based on what you've heard which one would you own?
