Jburidan, we also sell the Aqua, we have a Formula and a Lascala Mk II on display and we are not going to say they don't sound good.
We would also ask you have you heard a Lumin T2 or an X1.
The X1 is an extraordinary digital product one of the best sounding front ends we have ever heard, it is magical and it also uses a Sabre dac.
Their are many great dac chips from AKM, Sabre and Burr Brown including the 1796 and the 1792 chips what really matters is not the chip but how you impliment your design. R2R dac chips and the best multi bit chips are sounding more and more alike these days.
However, again, you are basing your love of the Aqua on just the chip the Aqua analog stage is superb.
This discussion is about Streamers both the PS audio and the Lumin are streamers the Aqua Hifi is not a streamer so you can't really bring up one in the same conversation also the new La Voice MK III is $4,750 add in a good server and you are in the $7k or so catagory so not a valid comparison unless you are talking one $7k package vs another.
