Wall of Sound Open Baffle Speakers

“With a stated sensitivity above 95dB, the Quintet 15’s sounded nearly as airy and easy on these ears as did the big and outrageous Stein Music horns that debuted at the High End show this past spring. What was even more impressive was the new and, for me, totally unheard of Whammerdyne Truth 4 watt SE amplifier ($16k) that powered the system to realistic sound levels. One thing’s for certain: there’s a lot to be had here for under $10k and the Pure Audio Project Quintet 15 may be one of the best values in high-end audio in the here and now.”

Clement Perry , StereoTimes, RMAF 2017 review
