Est. year: 1987

Concert Fidelity is the Japanese tube-electronics label of designer Masataka Tsuda, who launched it at the 1986 Japan Audio Fair in Tokyo with the SPA-4A, a no-feedback, FET-based moving-coil phono preamplifier. It is a small, designer-led operation building preamplifiers, phono stages and amplifiers in limited numbers.

Range & what it's known for

Known models include the CF-080LSX2 hybrid line preamplifier, the CF-i300B integrated amplifier with a pair of 300B output tubes giving 9 watts per channel into 8 ohms, the ZL-120V2SE monoblock power amplifier and the SPA-4C phono stage. The SPA-4C was made in a run of 40 units because it relies on scarce Japanese J-FETs from the 1970s. Tsuda's approach, which he calls Direct Signal Path Technology, keeps the number of active and passive parts in each circuit to a minimum.

Who owns it and where it's made

Concert Fidelity belongs to Masataka Tsuda, its founder and chief designer, who has more than 45 years of experience with tube and solid-state amplifier design. He also runs Silicon Arts Design, the name he uses for his solid-state work, while Concert Fidelity carries his tube designs. The products are designed and made in Japan.

The lineup in this catalog

Network integrated amplifiers. List prices for Concert Fidelity models sit between about USD 5,000 and USD 15,000.

Who it's for

Experienced listeners comfortable with small production runs and with hand-built Japanese electronics from one designer make up the audience, with the 300B integrated as a compact first purchase and the separate preamplifiers and monoblocks for a larger system later.
