I own an Audio Research DAC (ARC Reference CD9SE). For some reason, I just never thought of ARC when it comes to DACs. Until my dealer brought one over. I was not in the market… 30 seconds after I put it in I texted him to tell him to order me one… then I had the job of figuring out how to find the money.
Since then, I had a Berkeley Alpha Reference 3 in my system. Both absolutely outstanding DACs. I was expecting to have to cough up another $5K to get the Berkeley. I was really surprised to find them virtually identical with an ever so slight (tiny) warmer more natural sound for the ARC and a slight (minuscule) more detail in the Berkeley. If they were the same price I still would have chosen the ARC.
