This is a unity-gain buffer amplifier with a balanced output stage. It will convert any CD player or DAC into a balanced output tube DAC / CD player (RCA output also available) . With this buffer, the output impedance of any high impedance output will be converted into a lowered output impedance, greatly enhancingthe output driving capability .The signal will become more transparent, airy and dynamic for a much more natural sound.

Since this model uses large size tubes, the feeling of airiness and warmth is beyond description. With this model’s balanced output, you can enjoy the best dynamic performance of fully balanced amplification. This unit can also be added to the output of a conventional RCA output pre-amplifier, in order to convert your pre-amp into a truly balanced output device.

This buffer can even drive a headphone output with upgrade, for a small fee of c$150, you can convert this buffer into a headphone amplifier with about 1Wx2 of output power, which can drive almost any headphones available.

(Options: balanced input and balanced output versions for an additional cost of C$300 (5 tubes version , 6L6G x 4/2 + 6G6Gx2)), or C$600 ( 7 tubes version) . Solid oak chassis add C$200 , photo set below shows the BUF-103-BAL version withf 7 tubes, it serves the purpose of both converting RCA into balanced and converting a balanced signal into RCA, as well as fully balanced and full RCA operation) , for customer expect to use this buffer in between pre-amp and high gain SS power amp, we have a 5 tubes fully balanced version without conversion , which will have lowered noise floor , lower output impedance and smoother tonal quality.

Additional inputs add $100 for each pair (including RCA inputs and selector switch)

Super rectifier built-in upgrade (BUF-103-STR)

(Note: The upgrade price are special deal for newly order unit only, modification of existing unit will cost $200 more due to extra works)

Level 1 upgrade : (+ C$200)

Special designed "Super-Drive" circuit, output impedance lowered to 200ohm (can drive any input from 600ohm up to infinity) with better bass control and punch , better definition and improved in overall tonal quality. By adding this upgrade, it sounds like the output with 10x tubes being used. With this level of upgrade, just add $80 and you can have a headphone output with enough power and current to drive your headphone directly.

(optional chassis : Mirror steel, black piano , solid-oak )
