I bought one of these several months back on the used marked and really like this damn thing. Really good build, ss, coaxial or tube buffered outputs...replaced the stock op amps (NE5532) with two upgraded ones (Burr Brown OPA2134), installed a Tele 12AU7. This a damn fine sounding CD player. Supposedly based on the PCM 1732 DAC. Well built unit with toroidal power transformer and same transport as Rega Planet. I used to own the Unico P integrated so I can and will include the stock 12AU7, a Telefukin, plus a nice handful of (without looking in the box in the closet, at least 6 other 12AU7's) nice old stock tubes to roll. You will not find a better sounding CD player at the price I am offering, period. The original opts will be included as well...

"HD-19 HDCD vacuum tube CD player with remote
Like its older sibling, the Bada HD-22, the HD-19 delivers audiophile HDCD performance. But this time Bada delivers the quality at a competitive price point that will definitely surprise you.
The elegant design of the HD-19 uses proven high-quality Sony laser optics and the same Phillips servo circuitry as found in the HD-22. Digital to analog (DAC) conversion is through a 96 kHz 24 bit Burr-Brown PCM1732 respected chipset manufacturer is coupled to an audiophile grade 6N3/12AU7 output tube or, if you prefer, an OP AMP buffer.
Dynamic and Clean Performance
With an extremely high quality power supply, and the HD-19 delivers incredibly low levels of distortion of only 0.005%. An excellent signal-to-noise ratio, 110 dB dynamic range, and very low jitter add up to one impressive set of specifications.
The chassis of the HD-19 guarantees minimal resonance, ensuring ultimate sonic performance. Such solid construction is enhanced by a solid aluminum front panel that is also striking to look at.
If audiophile performance alone isn't enough, the HD-19 offers both tube and solid state outputs, coaxial digital outputs and the same remote control that the Bada HD-22 uses.
