The Allnic OTL headphone amp is the heir apparent to OTL goodness...read transparency. Unlike most other OTL headphone amps, it has ridiculous drive in the process. We offer this with the new Enigma Headphone or, for complete transparency, the new HiFiMAN HE-1000. Because the new 32 bit dac from Allnic is a work of art, we're including it here as well...it is pricey and you can hear every ounce of why. We also use this with an Allnic vinyl front end. Tears, tears, to hear it.
