I bought a used copy, which arrived today, and I was very pleased to see that it had been autographed! Excellent playing and sound. Yarlung uses a minimalist approach (a single stereo tube mic, tube electronics, and records to both analog and hi-res digital--not sure which they used for this recording), which results in tangibly real sound.
For Beethoven's birthday today. Shimkus' Op.106 is still my reference for both the performance and the fantastic sound.
