I'm sure the above recommendations are great, but I'll throw out another option.
I just heard the Ack Dac for only about $500 and was very impressed. You could spend more, but there's little guarantee you will get better performance, especially a stock piece under $3k. A modded piece may be a better option if you are determined to spend more.
Of the items you listed though, I think the Meridian would be my choice.
