CD player for a stereo: the Yamaha CD-S303, and what the lab numbers say
Updated 2026-11-08 · Pick: Yamaha CD-S303 · Dealectric link: DM13, $164.99 on Amazon (checked 2026-11-12), buy on Amazon: https://www.amazon.com/dp/B0DKXDKBG5?tag=dealectric-20
Short answer. For a stereo, the Yamaha CD-S303: RCA, optical and coaxial outputs plus USB playback. Lab tests put it and the Denon DCD-600NE at the same 95 dB noise floor (95.7 vs 95.3 dB), so the Denon's higher rated specifications buy nothing, and it has no coaxial out.

How this table was made: each figure comes from the maker's own US product page or manual, or from the reviewer named next to it, checked 2026-11-08. Dealectric does not test units itself. Rows with a Buy link are products Dealectric lists: the links are affiliate links, and their codes are re-tested in the brand's own cart every day (last check 2026-11-13).
| Model | Outputs to the stereo | Noise floor (lab-measured where tested) | Plays files from USB | Headphone jack | Price | Buy |
|---|---|---|---|---|---|---|
| Yamaha CD-S303 | RCA analog, optical, coaxial | 95.7 dB dynamic range measured (Audio Science Review); 105 dB rated | Yes: MP3, WMA, LPCM, AAC, FLAC | No | $499.95 (Abt, 2026-11-08) | |
| Denon DCD-600NE | RCA analog, optical only | 95.3 dB A-wtd measured (Hi-Fi News); 112 dB rated | No | No | $499 (maker, 2026-11-08, out of stock) | |
| Cambridge Audio AXC35 | RCA analog, coaxial only | >95 dB A-wtd, maker rating | No | No | $449 (maker, 2026-11-08) | |

What the differences mean
On paper the Denon DCD-600NE leads the Yamaha CD-S303 by 7 dB of signal-to-noise (112 dB rated against 105 dB). On the bench the gap disappears: Hi-Fi News measured the Denon at 95.3 dB A-weighted and an Audio Science Review member test put the Yamaha at 95.7 dB dynamic range, a 0.4 dB difference in the Yamaha's favour and far below anything audible on a stereo. So the pick comes down to how each player connects to your amplifier.
Output level matters for volume matching. The Denon measured 1.92 Vrms and the Yamaha 1.74 Vrms: 20·log10(1.92 ÷ 1.74) = 0.9 dB, so the Denon plays about one notch louder at the same volume setting. Against the 2.0 V CD norm the Yamaha sits 20·log10(1.74 ÷ 2.0) = −1.2 dB, the Marantz CD60's rated 2.2 V sits +0.8 dB and the FiiO DM13's rated 2.5 V line out sits +1.9 dB. None of these needs a different amp input; a plain RCA line input (CD, AUX or TAPE, never PHONO) takes all of them.
Price spread: the Marantz CD60 at $1,100 costs 2.4× the Cambridge Audio AXC35 at $449, and what it buys is a headphone jack, hi-res USB files and a 118 dB rating that nobody has yet put on a bench.
| Your stereo | Pick | Why |
|---|---|---|
| Amp with RCA, optical or coaxial input; you also have music on a USB stick | Yamaha CD-S303 | All three outputs plus USB; bit-identical optical output when used as a transport |
| Amp with an optical input only, analog listening, and you find one in stock | Denon DCD-600NE | Same measured noise floor as the Yamaha; optical out only, no coaxial, no USB |
| Amp with a coaxial digital input and the lowest price for a full-width deck with remote | Cambridge Audio AXC35 | RCA plus coaxial at $449; no optical, no USB |
| Headphones at the player, DSD and FLAC files over USB | Marantz CD60 | Headphone output with three gain steps; RCA, optical and coaxial |
| Desk or bedroom stereo, battery and Bluetooth wanted | FiiO DM13 | Optical or coaxial out, 2.5 V line out, at least 10 h battery |
What the lab measurements show
Yamaha CD-S303 (Audio Science Review member NTTY, test CD and audio analyzer, 2025-08-13): THD+N 0.0022 % at 0 dBFS against Yamaha's 0.003 % rating; dynamic range 95.7 dB without dither; output 1.74 Vrms with channels matched within 0.06 dB; low-level linearity off by 0.8 dB; digital filter reaching −50 dB near 24 kHz; 8 s to read a 40-track table of contents; plays through scratches up to 1.25 mm. The optical output produced traces identical to the source file, so the author called it a "perfect" transport while being disappointed by the analog stage. For a stereo with its own DAC, that is the useful half.
Denon DCD-600NE (Hi-Fi News lab report by PM, 2024-03-08, published as DCD-600): A-weighted S/N 95.3 dB against Denon's 112 dB rating; distortion 0.0013 % at 0 dBFs and 0.046 % at −30 dBFs; jitter 480 psec; maximum output 1.92 Vrms from a 955 Ω source impedance; frequency response +0.35 / −0.09 dB from 20 Hz to 20 kHz; stopband rejection 63 dB; 6 W measured draw against the 12 W in Denon's manual.
Onkyo C-7030, Cambridge Audio AXC35, Marantz CD60: no independent lab test exists for any of them, so their 107 dB, >95 dB and 118 dB figures are the makers' ratings. Cambridge's >95 dB A-weighted claim is the only one that matches what the other two players actually measured.
Pure Direct caveat. On the Yamaha CD-S303, Pure Direct shuts down the digital audio output and turns off the display (Yamaha's description, as printed on Abt's spec page). If the stereo is fed over optical or coaxial, the mode must stay off or the amp goes silent.
Not recommended
Onkyo C-7030. Onkyo's US site redirected its C-7030 product address to the onkyo.com home page on 2026-11-08, and Onkyo's CD-player page that day listed only the C-30 and the DX-C390, so there is no current maker price or listing to buy against. Its RI remote link works only with Onkyo RI-equipped components and needs Onkyo's RI cable (Onkyo Product Support). A used one still suits an Onkyo-receiver owner, but it is not a new-purchase pick.
Denon DCD-600NE for a coaxial-only amp. The manual lists one optical output at −15 to −21 dBm and nothing coaxial, and Denon's US store showed it out of stock at $499 on 2026-11-08. Buy it only if the stereo has an optical input or you will run analog RCA, and only when it is back on sale.
