Onkyo C-711MLTD (circa 1994)
The Onkyo C-711MLTD is a limited-edition CD player from Onkyo's INTEC component series, introduced around 1994 at ¥50,000. It's built on the standard C-711M. The "LTD" suffix means Onkyo fitted carefully selected parts in pursuit of maximum signal transparency - shielding, premium internal wiring, and a heavily damped chassis.
The design priorities here were isolation and vibration control. The C-711MLTD uses a CD mechanical shield construction, a shielded transformer, and a DuPont CORIAN insulator chosen for its rigidity and vibration-damping properties. Onkyo also fitted a very thick power cord with polarity display and an LC-OFC class 1-pin cable with spot connection and directional display. The single-bit D/A converter is equipped with FPCS. Frequency response is 5 Hz to 20 kHz, total harmonic distortion is 0.005% (1 kHz), channel separation is 90 dB, dynamic range is 96 dB, and signal-to-noise ratio is 100 dB. The unit draws just 8 W and measures 275 × 79 × 308 mm at 4.5 kg.
The C-711MLTD was designed to work within an INTEC system. It supports continuous peak search and CD editing/recording when paired with the K-511M or K-W511M cassette decks (not with the K-511THM), and it can be linked to the system remote control of the A-911M, A-911MLTD, or R-811M. Used standalone, it responds to the optional RC-133C remote. No contemporary press reviews have surfaced in the archive's research, so how it sounded or was received remains thin on record.
A single auction bid of ¥8,000 was recorded in March 2026.
