Hi. I use a Metronome C1A DAC, which combines 24/192 upsampling and tubed output and which replaced my previous AA Prima dac. In my ears the Metronome is the better sounding. You can find info on the website of Metronome. There are a few previous models of Metronome integrated cdplayers for sale here on Gon. I never heard them, but I guess they offer kind of the same color of sound.
