Ricky Skaggs-Live in London(CD). This was recorded and mixed using the 3M 32 track digital recorder. Most importantly it gets the tonality and timbre right, producing a relaxed and liquid sound. Even if the bass and treble are not SOTA there still well above average. My source is a Northstar Sapphire which takes joy in finding any flaw in a recording. Believe me this is a very clean recording.
