VL19 preamplifier


VL19 is a high-fidelity fully balanced line stage preamplifier with digital remote control. VL19 employs two 6H30Pi “super triode” per each channel in wideband balanced topology for signals amplification. A total of four 6H30Pi is used in VL19.

VL19 is a single-stage preamplifier without employing global negative feedback. A single-stage preamplifier has less phase shift compared with multi-stage preamplifier. Additionally, since no global negative feedback is used, the purity of musical signals can be faithfully preserved.

Wideband MOSFETs are used in active current source for improving balanced signals integrity. Premium grade electronic components such as pure silver interconnecting cables, copper foil in oil capacitors and low noise R-core power transformer are extensively used in VL19. Advanced high precision DC regulated power supplies are used to improve overall stability and sonic performance.

VL19 comes with a digital remote controller for easy operation. Volume control can be finely set in 99 steps.

"...I am pleasantly surprised to see the JE combination comes as close as I've yet heard to extracting huge amounts of music and timbral detail...It is not only gripping to hear the wonderful range of Mahlerian orchestral colours, but it exudes a confidence and solidity that illuminate the music brilliantly...I am not sure I can think of a solid state team that can produce this quality at this price point." Rafael Tode of HiFi World. 

 

The JE Audio VL19 line-stage provides an excellent sonic experience, makes a great visual statement, has just about all the convenience features one would want in a line stage, is built to a high quality standard and is reasonably priced." (Click here to read the full review.)
