RP-8.1  The Ultimate E-OTL  Headphone Amplifier- ( Vacuum Tubes input, Solid State High Current Output)
 

The RP-8.1  represent the latest update od RP8 series;  the highest level, the state of the art in our research in  E-OTL headphone amplifiers. The updated look is paired by e new tuning, making it our best E-OTL of ever

RP-8.1 it's a no-compromise device from any point of view. The sound  joint the warm signature of tubes with the punch and dynamics given by solid state power output, based on bipolar transistors.

The oversized and overfiltered double ( one for channel ) powers supplies deliver a clean and abundant current, in order to easily manage any power requirement even under the most stressing situatio

Frequency response if almost flat from near to 0 Hz up to 100Khz, and although RP-8 do not use any global negative feed-back in the  circuitry, it have a totally black background with no humm or hiss at all.

.Thanks to the great damping factor and the high output current the RP-8 can handle any kind of headphone no matter of impedance or sensitivity

As a standard feature,  the RP-8.1 offer a "pre-out" set of RCA ( output contolled by volume knob ) making it an extraordinay preamplifier.

The great quality constructiuon meet an accurate selection oif components including a special selection of crio-treated selected tubes.
