I have Tempus 77 Magnat for over 7 years now. I have had NS555 Yammies as a set with NS333 and Sub+ the center. I sold NS 555 within 2 months, NS 333 4-5 month later. They produce huge bright treble. After 1 hour listening one would get headache. I couldnt even keep NS333 as surrounds. Beside magnat i Have currently many pairs large speakers: Mordaunt S. MS 908, MS Mezzo 8, Boston VR2 , Paradigm monitor 7 V7 just a few to mention. The only close together in bass area are Tempus 77 and Boston VR2. Boston beats NS 555 any day in bass and mids. Tempus is not bright, proper 3ways. Powerful speakers. BUT placing is sensitive. I placed them close to wall on the sides of the room (coz i have 5 Pairs of large speakers) and they were very boomy , shaking all walls , doors and windows. i even thought to sell them. Then i Placed them at the front , away from wall - boom is gone! i listen them for rock and hip hop music all the time- no issues. Lv them. . Never again for NS555, and not NS 777- all are very bright and with bright amp Yamaha you will be turning the treble always to 0 or bellow while Bass to the max. It will unbalance image and mid part of freq. Very unbalanced speakers. I must agree there are some better speakers than magnat : KEF R11, New B&W (not the one mentioned here - not 603 S2, which are better than Yammie but not better than Magnat T77 ). Some Focals are just awesome !!! Some new 3 ways Focal are a must - my dream./ I havent swap my Magnat with KEF Q550 and Paradigm monitors 9 V6. Magnats are better IMO. Yummies NS 333, 555. 777 are NO GO!!! at least for me. And i have tried, owned and listened to much more speakers than i listed above.
