RP 5.3 Tridens   Hi-End   Headphone Amplifier- ( Vacuum Tubes input, Solid State Current Output)
 U.S. webshop
The best RP5 of ever

 

 

The  input stage of  RP5.3 uses three double triodes, while the output is a SS pure Class-A bipolar power transistors high current unit. This hybrid technology make possible to have a direct output without using a transformer, and this way offer all the natural sound produced by the input tube stage without the slow sound, typical of the classic OTL tube amplifiers, we call this technology "enhanced output transformer less" E-OTL. In the RP5.3 the best of the tubes, work together with the best of the transistors worlds

RP5.3 is a highly musical amplifier, the tube input stage give to the sound the warmth of tubes without any artificial color, and the high current output can perfectly handle headphones of any impedance.

The frequency response is almost flat from 2Hz ~ 50KHz (< 1db). The amp is cased in a heavy aluminum box. Wiring is made using only silver cables. The harmonic distortion is reduced to a mere 0.2% at normal listening levels. The IMD (Intermodulation distortion) is completely negligible.

The RP5.3 “Tridens” use a "capacitance multiplier" power supply and an oversized power transformer in order to assure the right amount of clean current to the audio section.

 

CNC machined aluminum black or silver anodized faceplate and handcrafted chromed brass knob clearly show the superb handwork

 

 

 

 

The "Tridens"

 

Tridens ( Trident in ancient Latin) circutry is a very low noise input stage using three triode section for each channel,

Inside the RP5.3

 

 

 

  RP5.3 Tridens  use selected components, an high precision potentiometer, matched vacuum tubes

 

RP5.3 is made using leed free components and soldered with a leed free tin/silver alloy. In respect of enviroment as for EU directive
