As we have seen over the last several years, the Park family has been very busy in their development lab.  Part of this intensive effort has been focused on designing an all-new product line, and today, Allnic is pleased to introduce its ASRA series of electronics.  In Korean, ASRA (pronounced “Ah-srah”) describes something faint, distant, and profoundly deep, evoking spaciousness, depth, and a refined sonic atmosphere.  The goal with ASRA is to draw on Allnic’s more than 30 years of innovative vacuum tube circuit design and apply it to a sub-$10,000 USD product line that still meets Allnic’s rigorous standards for exceptional sound reproduction.
 
The ASRA / RHPA-7500 is the first of four ASRA products being introduced by Allnic.  All ASRA products feature in-house, hand-built transformers designed specifically for them.  The use of the powerful 7558 pentode beam power tube simplifies the circuits in output transformer-coupled headphone and integrated amplifiers.  
​
The HPA and integrated models can include, as an option (for an additional fee), a newly designed 41-Step Constant Impedance Attenuator (CIA), a simplified version of the world’s first, and still unique, CIA, found on Allnic’s top preamps, integrated and headphone amps.  The ASRA designs all contain select, conveniently modular elements, allowing the owner to upgrade some parts or add accessories as they are developed.  The last image above reveals the internal construct of the 41-Step CIA.
​
Allnic has been manufacturing its high-purity Nickel Output transformer in-house for over 25 years and today is widely recognised for minimising the tonal coloration typically associated with output transformers.  It pursues an openness and purity approaching that of OTL designs. The intent is to preserve both the textural richness and transparency unique to tube amplification.  As a result, despite being transformer-coupled, the RHPA-7500 exhibits fast response and minimal loss of fine detail.
 
This model features a True Ribbon Direct Drive, dedicated XLR output, for optimal sound when using RAAL headphone line.  Danny McKinney at Requisite Audio will be at many CanJam shows and other meets throughout the year.  Visit and listen!  Professional reviews are ongoing and linked here when available.
