Jadis JPL Monoblock Tube Preamplifier Preamplifiers

Jadis JPL Monoblock Tube Preamplifier Preamplifiers 


Jadis' JPL Monoblock Tube Preamplifier features a CD input with a tube impedance adapter, more regulation and a stiffer power supply than it's siblings. These, along with monoblock internal design, make it a favorite for those who do not need a preamp with built-in phono stage.

silky high, extended bass, very dynamic, open and airy sound.


None as I can perceive. Gain (35db may be a little too high for some system. However, if you are looking for more "romantic sound", Unison is a better choice.

Just acquire a JPL of early production (circa 1992). Very high quality parts (Rifa, Philips etc). Immediately change the tubes into Amperex Bugleboy 12AX7 (x3). Silky smooth sound. Extended well from top to bottom end. Surprisingly, very dynamic sound for a tube design. The seller lend me a Unison Research Mystery One for comparison. Unison is more nostalgia kind of sound (perhaps because of tube rectification?), warm and romantic. However, Unison's treble is obviously rolled-off compared with JPL. Bass extension is about the same. JPL is thus more "modern" sound. In terms of look, both are good, though Unison seems to be more unique in terms of design. I wish I can keep both of them and use Unison with Apogee Diva and JPL with Sonus Faber Extrema...
