The Gavler Verdict
Precision Engineering
6N8S + 6N5P Tube Circuit
Classic tube pairing produces warm, harmonically rich sound with the spaciousness and depth that solid-state amps cannot replicate.
Tube Rolling Compatible
Standard socket types accept 6SN7, 6AS7, and 6080 tube variants for customizable sonic character that evolves with your taste.
Output Transformer Topology
Proper tube amplifier design with output transformer — not a hybrid tube buffer — delivers authentic tube amplification.
Technical Specifications
The Scoreboard
Tube enthusiasts rate the TA-26s exceptionally highly for its price-to-tube-magic ratio. Objectivists note the output impedance is too high for low-impedance headphones and the measurements are mediocre — but tube lovers do not buy tubes for measurements.
