I couldn't bear to listen to these for long because I'm currently listening to the finest-sounding stuff in the world, a new album from Marley's Ghost, 9624 or 1/2" (we haven't decided yet which to use), absolutely open, clear, dynamic, pure, great performances, vocals are recorded naturally and in a real room not on top of the mike, a wonderful set of acoustic instruments and arrangements by the group, produced by Van Dyke Parks.
In contrast, Father, please forgive me, my ears took a shock listening to this test stuff. The compression/limiting is obviously part of the sound, the up front, edgy stuff. Well, anyway, after a period of ear-adjustment, I preferred Tango over Uniform because Tango sounds "wider". Sierra is far behind, very distorted and ugly. Ironically, I dropped Tango by 0.2 dB but it still wins.
Let the games begin.
