Just look at the measurements!
As with the Hegel Music Systems Mohican, which we reviewed in the May issue, the Bryston BCD-3 has no digital inputs of any kind. This limited my measurement of its technical behavior to using 16-bit test files burned to a CD-R. (I sometimes had to eject and reload a CD-R several times before the BCD-3 would play it.) I tested the Bryston with my Audio Precision SYS2722 system (see the January 2008 "As We See It").
The Bryston's error correction was excellentno glitches were apparent in the player's output until the single gaps in the data spiral on the Pierre Verany Digital Test CD reached 2mm in length, or the closely spaced double gaps reached 1.5mm. (The Compact Disc standard, the so-called "Red Book," requires only that a player cope with gaps of up to 0.2mm.) The maximum output level from the unbalanced outputs was 2.02V; as expected, it was twice that value from the balanced outputs, at 4.05V. Both outputs preserved absolute polarity (ie, were non-inverting). The balanced output impedance was a low 143 ohms at 20kHz and 1kHz, rising inconsequentially to 160 ohms at 20Hz; the unbalanced impedance was 72 ohms at 20kHz and 1kHz, 77 ohms at 20Hz.
Fig.1 shows the BCD-3's impulse response; it's typical of a minimum-phase reconstruction filter, with all the ringing occurring after the single sample at 0dBFS. Tested with white noise sampled at 44.1kHz, the BCD-3's output rolled off quickly above 20kHz (fig.2, red and magenta traces), but hadn't reached full attenuation by the Nyquist frequency, 22.05kHz (fig.2, vertical green line). Nevertheless, the aliased image at 25kHz of a full-scale 19.1kHz tone (blue, cyan) is suppressed by 100dB. Note also how low the distortion harmonics of that tone are. The blue and red traces in fig.3 show the Bryston's audioband response taken with spot tones; it is flat, and reveals excellent channel matching. The cyan and magenta traces in this graph show the response with preemphasized data. The slight lack of energy in the mid-treble seems to be typical of modern CD playersthe Hegel Mohican behaved identically (footnote 1), perhaps due to the fact that it uses the same AKM AK4490 DAC chip as the BCD-3.
Channel separation (not shown) was superb, at >120dB above 200Hz, while the analog noise floor (fig.4) was both very low in level and free from any power-supplyrelated artifacts. Fig.5, the spectrum of the player's output while it played data representing a 1kHz tone at 90dBFS actually shows the low-frequency spectrum of the dither noise used to encode the 16-bit test signal. With undithered data representing a 1kHz tone at exactly 90.31dBFS, the Bryston's low self-noise allows the minimum-phase ringing on the waveform transitions to be clearly seen (fig.6). The three DC voltage levels described by the data are well defined.
Confirming the low distortion seen in fig.2, the spectrum of a full-scale 1kHz tone is very clean (fig.7), with just the third harmonic at 2kHz visibleand even then, it lies at 100dB (0.001%). I then tested for intermodulation distortion with an equal mix of 19 and 20kHz tones; the resultant spectrum looks hashy in the audioband (fig.8), but this is an artifact of the 16-bit encoding. Actual intermodulation products are very low in level even into 600 ohms, as are the aliased images at 24.1 and 25.1kHz.
Finally, though there is a slight widening at the base of the spectral spike in fig.9 that represents the high-level tone at exactly one-quarter the sample rate, all the odd-order harmonics of the LSB-level, low-frequency squarewave lie at the correct levels, shown as the sloping green line. The BCD-3 offers excellent rejection of word-clock jitter.

Just look at the measurements!
It doesn't play SACD's or DVD-A discs. Is a CD-only player really competitive in 2017? For less than half the price I can buy a top of the line Oppo (UDP-205) that plays every 5" disc in existence, plus uses the ESS 9038PRO DAC (and I bet it comes with a remote control at no extra cost). Something just seems wrong with this picture...
while not inexpensive, based on AD's review and JA's measurements, this seems to be a very well made and great sounding CD only player. I'm sure the Oppo is a good machine. I've only read great things about its blu ray capabilities. Enjoy it. But it's not a proper comparison.
The point is if it can play CD audio better then a modern day SACD or DVD machine can play CD audio then it's worth owning even if it cannot play SACD or DVD audio. They made these and tuned them specifically for CD audio.
Ah, I remember - those are the hard media things you used to rip so you could store AND FIND the songs and play on a music player, like the excellent Bryston BDP P1 (less than $1,500). Or if you want to go all out, the BDP 2 (less than $2,500). Either of these solutions seem superior to the silver LP solution.
of the future or even the present for that matter, it's a review of a cd player - which, considering how many companies are still investing in new state of the art players and considering how many people still have massive cd collections - is still a viable and often great sounding format for reproducing music.
... and the specs of the individual components, you'll see that the transport and all the digital processing circuitry are all fully capable of reading and decoding far more formats than Redbook CD. It comes as no surprise that the CD measurements are going to be great, as modern transports and DACS designed to decode 24bit/192kHz files and greater are not even breaking a sweat when it comes to CD playback. It's not as though they've employed some "super special CD only components" to make a machine that will outperform every multi format player. It's more like they built a high quality multi-format player and programmed out the "multi". At least, that's how I see it . YMMV.
Hegel is doing the same thing w their Mohican CD player. Over-engineered and optimized for purely redbook cd playback. Not another piece of electronics wasted for anything other than that. I get your point but it's a little like criticizing a $35000/ 100 lb. PASS amplifier for only being a mono block and not being for that price and size a maasive home theatre amplifier.
Looking at the owner manual of Bryston BCD-3 CD player, I found that the program function is missing. Why?
$499 Marantz CD6006 and $1499 Onkyo C-7000R have the feature.
It is just a little bit of coding, but Bryston skipped it for their $3495 CD player?
Or omitting the programming feature leads to better sound quality?
Once again, criticizing a feature that has no direct impact on SOUND QUALITY is missing the point of this review and the product and others like it.
Another analogy - it's like someone criticizing a $10,000 turntable/cartridge/arm combo for only playing one record at a time. Yes, back in the 60s you could buy $69.00 turntable that could stack record after record!
Single record playing turn tables are designed that way to achieve better sound quality.
By skipping the programming feature on a CD player, do they achieve better sound quality?
Nicely done- AD!
have any of guys compared this new BCD-3 to the older BCD-1 spinner?

its intrinsic resolution is better than is needed by the CD medium, then what does the Bryston unit do for about 10 times the price?
I have tried over 100 CD players in the past 35 years. The Marantz CD5004 is a smooth and generously rich sounding player. I also suped it up with new power and filter caps, etc. but it still sounded lacking in resolution to start with and just okay. A Denon 1500 and Kyocera 310x wipes it out. I now use a radically altered Benchmark HDR1 Synergistic Research Atmosphere X Euphoria cable and a suped up Arcam Delta 250 transport with high end power cables. It KILLS the Marantz. The Bryston uses the same or similar transport used in the Project RS2T ($3.2K) 1Aqua Audio Diva II (Current version) about10K 2 Acustic Arts Drive II about 17K 3 Gryphon ETHOS CD player 35K. Stream Unlimited transports. I'd like to hear it.
