I just installed my new LTA Aero into my system. It will probably sound better over time, but to me that would just be icing on the cake. This DAC sounds amazing right out of the box. I'm using a matched pair Tung-Sol black glass, round plate 12sn7 tubes that they recommended. Sure the tubes and the DAC will have a burn in period, but it doesn't seem to need it at this point. I bought the LTA to upgrade from the native DAC in my Bluesound Vault. I was considering two other DACS, the Schiit Yggdrasil - which I hear needs over a month to start sounding good, and the Geshelli Labs Dayzee - which is currently not in production and being re-designed.
We'll see how much more time playing improves the sound, think it will be subtle steps that will evolve over time - tubes and tube equipment...
