I am looking for a smoothest sounding outboard DAC

I heard a complete Audio Note System at Audio Limits.
Wow!!! it is unbelievable.. The Audio Note ANE SEC Silver Sigs along with Audio Note's M8 Preamp ,Kegon Monoblocks and the 4.1x Balanced is the ultimate. Even the Sogon Cable's are incredible..
I am selling my complete System to try and recreate what they have.. after visiting them I am a True believer in Audio Note. absolute worlds best..

It depends on what you mean by smooth.

There are a lot of DAC's out there that reduce the dynamics to sound smooth because there is so much sibilance otherwise. I prefer a DAC that delivers ALL of the music and dynamics without ANY sibilance. Frankly, the only place you will find this in an off-the-shelf product is the Meitner, unless you are willing to pay for mods to other DAC's. This is how I got there.

Snoops, I heard Peter's personal system and agree, at least for a certain focus in the music. Peter loves the emotion in old opera and in single instruments, and his electronic wrings it out of the recordings. I would think achieving that sound without just buying the entire system would be nearly impossible, but good luck.
