Beautiful tube sound from both headphones and speakers　

Selected high quality parts and design. HA-03 is unique designed tube amplifier for speakers as well as headphones. HA-03 uses same output circuit both for speakers and for headphones. The amplified circuit is Siemens vintage tube C3m, is pentode connected one stage amplify. Quiet simple structure. Non feedback, separate power supply for screen grid circuit and plate circuit.

Headphone side is 50ohms, 1.4W x2, speaker side is 8ohms, 1W output. 1W is small output, but considering powerful tube driving power, it is enough power for bookshelf speakers, except quiet low efficient speakers. Also it corresponds wide range impedance for headphones. almost any kind of headphones could be easy to be driven. Actual ideal impedance range seems be from 16ohms to 200ohms.

Insulated rigid wooden chassis and high quality parts..

Review

Impression of the sound is smooth, but clear shape of sound, blight and vivid tone color. Piano touch is clear and richness.

Excellent bass range for jazz. Sound field is huge, high density and excellent quality of feeling. I used SENNHEISER HD-650,

Genuine custom made product of exceptional quality.

山本くん最高!
The ha-03 is a brilliant amplifier.
What’s more, I’ve got a pair of antique SONY full frequency speakers from one of their professional studios.
4 inches,8ohms,2w, cobalt-magnetic type.
That’s really the best.
By the way, music is line-out from MP3 player _P6 of Luxury&Precious brand ,it uses an r2r-type D-A converter.
CD player ,by the way,is dcp-150 from Denon.
Power supplies _Oyade R0 sockets &Chord Company ChordMusic cable.
RCA-3.5,I don’t know the exactly brand .
