Wait, they make sound, too?
They do make sounds, very good ones.
I'm waiting on an upgrade to my dB Audio Tranquility SE DAC before writing up detailed impressions. For now I will say they are smooth, musical, natural, and excel at clarity (more than any speaker I've heard or owned (owned last ten years Salk HT1-TL; Omega 8 Superhemp single driver; Taylor Acoustics Taylo Reference Monitors; CBM-170 SE heard several other Salks, B+W 800s, Audio Notes, Magnepan, Monitor Audio, and a bunch of stuff at audio shows.)
