Hi, It is a model called SM-8949 and is not sold in the United States. Performance is fine for the money. However, it's uncomfortable because it smells like shoes for a while.
Recording was performed on a typical volume. In the real world, it's better than video. The two are similar, but the dynamics and the scale are different. You will listen to music with your body. If your space is big, you can feel the gigantic scale. And Single Point Source is really great.
The Merrill Audio is uncoloured and has excellent reproduce the sound-stage.
Makes me want to have a flagship products.
I highly recommend listening to Merrill Audio.
Thank you for your interest.
