@backdoor That DAC was part of the last of the "we don’t like Redbook" era DAC’s. Since then most good DACs have demonstrated such an improvement with Redbook that you almost don’t care about high resolution music anymore.
Not sure when this era of transition took place, but an interesting observation. I have had the same DAC (Yamamoto YDA-1a) since 2010 it is simply wonderful with Redbook CD playback. Paired with my Pro-Ject RS2T transport the music presentation is genuinely superb and natural.
So maybe some brands/manufacturers crossed the threshold to terrific Redbook 16/44 earlier than others. Nice topic. Listening to jazz guitarist Kenny Burrell as I type this. The CD is “Lotus Blossom “ and it’s beautiful and captivating. Long live Redbook CD.
