Roxy, Thank you for the comments. I also love the Adagios... "sometimes";....they have great bass, dynamics, and overall transparency... BUT IN THE NEGATIVE COLUMN, they can often sound bright, more so hard, and the sound is less than musical. But I have to join the chorus of members who own them, that yes the highs are a disappointment, not so much as how far they go out, but too often don't sound smooth even on the best of CD's.
I previously owned Silverline Prelude II which took a long time to break in, but were very musical before selling them to upgrade to the Adagios. Prior to that was a pair of Vandersteen 1C which were also good, but not as good as the Preludes. I also owned a pair of Green Mountain Europa's (bookshelf)which were one of my all time favorites.
My first really high end system goes back to 1988 when I had separates, and ran B&W Matrix3 MK II which were in the same league as the AZ Adagios, but also tended toward brightness and could be edgy, I always preferred a speaker with extended highs because I believed they would sound less warm, or less detailed, or simply too soft,especially on classic rock which is what I primarily listen to. . A member told me to check out the Wharfdale Jade 3 monitor or the Devore 3XL monitors ($3700) However, Devore's pricing is off the scope, and he highly recommends his stands to maximize the "sound quality" The stands are wel made, but costs $595.00. So the total investment is almost $4300....that is a bit outrageous. Though, the new line called Scansonic offers a similar monitor, B-1 and recommends their stands at $795.00 Wharfdale Jade 3 come in less money at $1500 for the monitors and only $500 for their stands.
