Shahinian Obelisk vs VandersteenTreo

Outside of hearing them I don't know.

again....use the phone and call Richard...hardworking dude picks up the phone....
he actually uses science and measures his speakers so IF there is a “ lower midrange suckuot” he would know and could probably tell you IF he made chages  to rectify that. he is all about continual improvement to the product. you might also look at the “ ask Richard” section of the website

       "the quattro's mostly solve the bass issues of the treo's"                    So will a pair of 2Wq subs. Actually, the Treo's don't really have bass issues. They just don't go quite as low as the Quattro's. Proper placement will enhance any speakers lower frequencies. As well as room treatment. I have listened to a pair of Treo CT's with 2Wq subs, and a pair of Quattro Ct's.  I preferred the Treo CT/2Wq subs to the stand alone Quattro CT's. So did the salesperson. In regards to my listening, just my opinion. Dynamics really stood out with Treo combo. 8 eight inch woofers for Treo combo versus 4 eight inch woofers for Quattro's.

+1 for mr_m.
OP, I thought you said you were in Russia? Where does the Italian keyboard come in?

probably a plot to make  it look like the Italians did it.....
