What is they best album out there for showing off the sound quality of your system.

Review about One Mic Recording by Joe Whip at Audiophile Style.

.....These guys and this recording just rocks. Pace, rhythm, tone and soundstage are just off the charts.
The precise placement of all four of the musicians perfectly matches the photos of the sessions.
The balance of all four instruments is darn near perfect. As you can no doubt tell, I am a huge fan of this recording.
It is one of the best in terms of recording quality I have ever heard. Of course, and as always,
your view of the actual music content may vary quite considerably from mine.
Nonetheless, I think we would all agree that this recording sounds sensational....

I’d go for the one microphone recordings from Sound Liaison. They are like having the band in your room. Btw they are on Black Friday sale this week.’’Carmen Gomes ’’Don’t You Cry’’Feenbrothers ’’Play Dave Brubeck’’Rainier Voet & Pigalle 44.https://www.soundliaison.com/index.php
