My first listen, casting from Tidal. I can actually hear both sides of the bass debate. It is audible, less so in the full on quartet passages but very definitely when it breaks down to a piano trio. And yes, it is a bit boomy but that doesn't detract too much for me, I'd rather it that way than thin or non-existent.
Overall I'd say its SQ is one of the better recently discovered live recordings. The music itself is pretty spectacular. I'll be buying this.
