I have to agree with your assessment of Mark Levinson. I spent a lot of time on the 90’s auditioning Levinson… and have actually had a Levinson system in my car for the last 15 years. It is very sterile… well accurate… polite, but to me extremely un-musical. I remember a major dealer told me that people that bought ML just called up and ordered it after a favorable audio review… they never came in and bought it as a result of auditioning. I was certainly never tempted. Did everything right… but no emotional connection.
It is interesting you put Rowland into the same class. A couple of the best systems I have ever hear (Wilson + Rowland)… but, yeah, while amazing there was a certain similarity. While I have to say as far as holographic the Wilson + Roland was the best system I ever heard…however, I did not want to own one. My current system is much more musical and satisfying, although it cannot do the acrobatics of the Wilson / Rowland).
Anyway. Interesting comment. I need to go find another Rowland system to listen to.
