Hi. yesterday got myself a 280F pair in Piano Black. The sound,.. well, I new it`s going to be good, but i was completely blown away. They sound exactly the way i want! So detailed and transparent, with enormous imaging and space, and botomless bass...AT ANY VOLUME! I paired them with my Denon pma 720ae and Denon DCD 720ae, and i can barely turn it past 11 o'clock not to blow out my eardrums...and windows. // In a speaker shop, salesman told me that my amp is total crap and diagnosed me wright away amp at 700+/- eur price, the way he spec amp for speaker was not by performance, but the price. So now I`m a little confused. Is it really not enough 2x50W at 0.07THD, 20-20KHz at 8ohms.?? my room is 15m2, with 2.5m ceiling. (160ft2, and 7.3foot high). What is your opinion?
