The highs were superb & I spent 4-5 years chasing the sound & finally got to SS Pass Labs & Tube preamp as end product.
Anyway, I've listened to a bunch of highly resolving speakers & the Mac's tamed the highs, always
Something about the transformer outputs?
But, not much bass as to Bryston/Pass etc
Anyway, There "new sound" is something you should try to listen with Thiels
Room stuff is good start ( start by hanging blankets at reflection points and see what you hear). It looks ugly, but works for " prove it to me" type of thing
I spent a lot of time with adjustments in electronics, cables, power to tame the Thiel uber resolution. I found Thiels very persnickety of upstream components for them to sound best.
I thought there highs were spectacular, after the right stuff was inserted
I made the change due to the lack of fullness in the lower ranges.
My goodness, I thought the Revels were so-so when listening at Axpona, etc
Amps make a huge difference for Revels in the low end. ML, so so on bass, but pass was different animal. Very full, like adding another couple woofers
Anyway, by taming the Thiels and then inserting the revels, I was pleasantly surprised how delicate the be tweeters are.
Delicate, resolving, lots of soundstage & more details to be heard.
The low level listening is great, greater than Thiels which excelled at it
System updated: Upgraded preamp with a new tube: Amprex 6DJ8 Up to this point I could not tell much of a difference with tube circuit in or out Now,In less dense music, There is a big difference in the sound. I now know what tubes do!! More depth,leading edge definition & euphonics; I am a fan.
Also,I have noticed the Peachtree amp gives the cymbals a "crushed leaves/glass" sound to the dense music of Rush,Van Halen,Foo Fighters etc. I Find that all the other styles of music are well delineated and crisp. I am debating a power amp change. ANY SUGGESTIONS?
