Nordost's Qk1: Not a Filter, a "Field Generator"
The QK1 is housed in a mechanically tuned carbon-fiber body and equipped with either a US (NEMA) or EUR (Schuko) connector. It is compatible with voltages from 110V to 240V. In keeping with its full-system approach to AC power and
signal transfer, Nordost touts the benefits of the Qk1 as being cumulative and even more
impressive when part of a full-QRT system. |
he latest QRT power product from
Nordost is the Qk1 ($249.99), which the company describes as "a load resonating
coil." When plugged into any spare outlet on an audio or video system's AC line, the
Qk1 generates a passive electronic field, which is said "to prevent time delay and
distortion of the transmitted signal, making the AC current as close as possible to the
desired 'distortionless condition.'" Sonically, the Qk1 "opens up midrange
frequencies and improves the attack of transient details." In terms of video
performance, the QK1 "increases clarity of imaging by adding depth and focus."
