Today I received my long-awaited copy of Aja, 45 RPM on 200-gram clear vinyl from Analog Productions via Acoustic Sounds. It absolutely blew me away; the soundstage was wider than the room, the instruments and vocals sounded three-dimensional and alive. At the beginning of the month, I downloaded the 24/192 version from HD Tracks, and I can report that it doesn't hold a candle to the UHQR vinyl. The digital version, by comparison, is less three-dimensional and the soundstage is narrower. It also requires more pre-amp gain than any other digital recording I own or stream. I tried enabling a convolution filter in Roon that I built using Acourate; it added some dimensionality but still failed to approach the vinyl copy. BTW my analog playback system is an LP-12 with an Ekos SE Arm and a Dynavector XV-1s cartridge, while the digital side uses Roon through a Bartok DAC. I'm planning to do the Apex upgrade on the DAC early next year, which should make the comparison even more interesting. Bottom line: if you like vinyl, buy this recording now - they're only pressing 1000.
