I know it'll make ol' CJRoss over at HFC unhappy, but that's life. I tried out the Meridian 588 ex Ian (Sideshowbob) with and without the TAG DAC20 and it doesn't improve the 588 at all. Most surprisingly of all, to my ears, the HDCD function of the DAC20 didn't make my one and only HDCD sound any better than did the non-HDCD 588 alone. So, thanks, Ian, your gain is also my gain! And before anyone says "better DAC", these require lots of money, the lots of money I don't happen to have. In any case, it all sounds rather good as it is [U]and[/U] I have one fewer box cluttering up the place!
