HP10

 

HP10 is a high performance stereo phono amplifier employing low noise solid-state semiconductor devices for signal amplification and a tube amplifier for output buffer. HP10 offers exceptional performance in terms of transparency, dynamic and extraordinary imaging capability at its price range.

 

The MC and MM input signals are handled by separate MC and MM phono amplifiers. They are independent amplifiers that have no common parts sharing between them. Therefore, this will ensure shortest signal path and no switch is used at the low level input signal.

 

Since MC and MM phono amplifiers are independent, each amplifier contains its own RIAA equalizer. We have chosen passive RIAA equalizer for HP10 because the elements of the equalizer have less coloration to the sound compared with active feedback RIAA equalizer.

 

A 6H30 tube buffer amplifier is used at the output. The 6H30 has very wide bandwidth, low distortion and low output impedance. It greatly enhances the sound of HP10 phono amplifier.

"The JE Audio HP10 phono amp is what high-end audio is all about. It’s an innovative blend of solid-state circuitry that ensures signal clarity with the life-giving magic of tubes at the output stage. It’s wonderfully built, thoughtfully designed and fully adjustable to accommodate a wide variety of cartridges and analog systems... Highly recommended." Dave Thomas of Stereo Times.

"This was superb imaging and wonderful soundstaging, not something I had to listen hard for. The HP10’s imaging prowess rushed out toward me... All that digging deep into the cellular structure of the JE Audio HP10’s sound is just minutiae. All you really need to know is that the HP10 is a neutral-sounding phono stage with excellent bass extension and imaging, and just enough sweetness to endear itself. How cool is that?" Jason Thrope of Soundstage. (Click here to read the full review.)

 

 

"... JE Audio HP 10’s bass is superb, digging as deep as the recording demands. Its midrange is superb, sounding as if the combination of its solid-state input and a tube-output are working in harmony to produce a component that reproduces a midrange that sounds neither solid-state or tube-like. It simply sounds like music, and this trait is a big reason why when it comes to its midrange, it seems as if the HP10 is an inaudible piece of the analog-chain." Tom Lyle of Enjoythemusic.
