They are nowhere near the class of speakers you are using. They are similar sounding to Monitor Audio S6's, and B&W 704's. Titanium tweets. I love metal domes. I am a drummer, and have been crashing symbols on several different drumsets through the years. Playing a set really puts the treble "in your face." I think this may be the reason I like metal domes so much. They just sound more like a real symbol to me.
I am not a speaker reviewer, so my terms may not be politically correct.
The B&W's seemed to have the cleanest sound, but not the fullest. I liked the tweets. The whole design to solve the shortcomings of the tweeter was impressive. The mids were tight and made (IMO) vocals lifelike. OTOH, there was no bass extension. The cabinets were a work of art. They were the most expensive. ($2199.90 a pair)
The Monitor Audio's had the fullest sound, but not the cleanest. The bass extension was great, but I think this caused the vocals to fall behind the quality of the B&W's due to the cone movement. The tweets were not the best of this bunch, but I did like them. The cabinets were classy. They were the least expensive. ($999.00 a pair)
The MB Quarts were a happy medium. The sound was clean, and full. The tweets were superb. While there was no fancy designed enclosure to solve the tweeters shortcomings, they seemed to have put the work into transducer itself. The bass extension was not great, but tight and snappy. The vocals came out lifelike, but slightly behind the B&W's. There is a little of the "boxy sound." The cabinets were 3/4" MDF, but not the best looking of this bunch. Priced accordingly in the middle. ($1699.99 a pair)
The decision was made based on the reasons above along with getting a great price break due to a whole system purchase.
