My take on ribbon drivers back in the 80-90's, were they sounded too bright with tube or Class a/b amps. But that might have changed with some of the newer ribbons. I went into the Heil room at RMAF in 2010 and again they were way too bright. I was only in that room for about 10 seconds, I was afraid of getting a headache. I am sure some people loves them.
Tommy's amps never has sounded too bright on any other speaker I have tried them on, but I still shy away from ribbons because of my past experience. Ribbons have always sounded metallic and sterile to my ears. But that is probably just me.
yes, Tom, I believe that is why the Cherry Amps are called "sweet".
the tech for Class D seems to have advanced exponentially in the last 10 years,
and the ribbon tweeters have only gotten better as well.
In particular, it is the high end Class D amp makers, eg Merrill, etc that are also able to make totally satisfied customers, b/c of the extra circuits and power involved, creating very accurate and musical sound.
It just makes me wonder, if the Cherry is sweet,
how does death metal sound? sweet?!
