I bought the Mezzo 6 a couple of weeks ago after auditioning KEF iQ9, Polk, JBL ES100, 90, 80, PSB T65 and a few others so here is my take. But first I need you to know the kind of music that I listen too. Its completely eclectic and ranges from Luciano Pavarotti and Tchaikovsky, to Floyd and Scorpions as well as Nazareth and Iron Maiden....and to blend it in I also have Elvis, Pat Boone and Shania Twain to name a few. I went nuts trying to find the right mix of speakers and amp.
The KEFs were good for the Classical stuff but got butchered by Polk and JBL when it came to the heavier end of my listening spectrum. The Polk handled Scorpions elegantly but were outclassed by the PSB in that department. So when I tried the Mezzos after all the fabulous reviews, my expectations were high. I checked them out paired to a Cambridge Audio 740A amp but found them lacking the 'thump'. I then re-read all th reviews and went back and tried them with the Denon 700 and the bass now sounded a little boomy. In parallel I was also trying out the amps and cd players - not a very smart move in retrospect, but I was on a time line.
So what worked eventually ?? Well I realised that what the Mezzos were missing in terms of the 'lows' was made up by NAD, and the mids and high's on the Mezzos sounded just right. So I paired the NAD 355BEE with a NAD 545BBEE CD Player, hooked this up to the Mezzos and what I got was pure magic. I cant believe the soundstage and have been loving every minute. My self proclaimed 'tone deaf' wife has also started to enjoy the strains of Enya as well as the highs of O Sole Mio and we soak up the joy of the music enveloping us every evening, with just each other and a glass of wine for company.
