Feliks Audio BLISS
The Feliks Audio Bliss is a fully balanced tube headphone amplifier for electrostatic headphones, with no output transformers. Four 6E5P driver tubes run in pure Class A, and the power stage uses four 300B and four EL34 tubes. The adjustable bias knob covers vintage 230V Normal-bias e-stats as well as modern 580V Pro-bias flagships, and there is both a 6-pin Normal and a 5-pin Pro socket. XLR and RCA inputs with selectable input sensitivity make it easy to pair with a high-output DAC. Matched Lundahl transformers and a 24-step DACT attenuator keep the channels balanced, and every unit is hand-built in Poland with a solid Oak, American Walnut or Zebrano finish.
