I have a trade-in Black PrimaLuna Prologue 8 tube CD player with the upgraded opamp board.
Reviews have all be exceptional on the fine player. It is an Absolute Sound Editors Choice and a Stereophile Recommended Component.
The chassis is made of heavy-gauge steel, with a "five-coat, high-gloss, automotive finish," each coating hand-rubbed and polished. The tube sockets are ceramic, the output jacks gold-plated. Inside, separate toroidal transformers power each channel. Custom-designed isolation transformers separate the analog and digital devices, to reduce noise. The power supply incorporates 11 separate regulation circuits. The output stage is dual-mono with zero feedback. Audio-handling chips include a Burr-Brown SRC4192 that upsamples "Red Book" data to 24-bit/192kHz, and one 24-bit Burr-Brown PCM1792 DAC per channel. It uses 12AX7, 12AU7, and 5AR4 tubes; its internal clocking device is a mini-triode tube instead of the solid-state oscillator found in most CD players. The tubes are said to last 10,000 hours.
