Description Freakuence!<\/strong><\/span><\/div>\n
One of the best-performing streamers we\u2019ve ever had here in the shop. Sure, it\u2019s pricey, so you hope for something\u2014but you don\u2019t know exactly what that should be. Now it\u2019s clear; we know. Above all, an incredible amount gets filtered out: detail, power, speed, depth….there are others that can do that, thankfully… but this device eliminates noise, distortion, and harshness\u2014they\u2019re barely there, if at all\u2014so everything that\u2019s left really pops! Very tangible, rounded, real. If you never go to unamplified concerts, stop by that street musician sometime, hoping he or she is any good, and listen to that instrument\u2014that\u2019s \u201creal-life analog\u201d; that\u2019s what we always hope for here and sometimes get just a little bit of. This streamer has brought us one step closer to that goal.<\/span><\/div>\n
