My 2 cents
this dac is legit.
did a shootout vs lampi GA.
much preferred the LTA in a double blinded test that I repeated and had the same results. More realistic sounding and thats saying a lot vs the lamp. i did upgrade to the ray 6sn7 which made a big difference. I honestly feel no need to further quest for a new DAC. This is a long term keeper. Dam good product and happy to support such a classy company. I've been through a TON of DACs over the years. The USB input from my Auralic streamer sounds perfect.
