Significantly deeper than any other player which makes it a pain to rack. Sound: very good until compared with any Tda 1541 DAC equipped player then it sounds like it's not put everything in the digital signal back together again very excitingly.īuild: over the top. It seems appropriate to simply list the pros and cons because it presents itself somehow as an inorganic assembly of good features that somehow add up to a lesser 'whole'. I tell myself the reason for this is that it is the only player of mine that copes with cd-rws. Yet at the same time I'm unlikely to part with it. Which adds up to longer life and cleaner audio.Difficult to know where to start with this odd device, because whilst sound wise it's pretty good, and the build standard is exceptional it's a curiously quirky thing. This method of construction prevents vibration from the chassis and CD drive mechanism from adversely affecting the circuit boards or creating signal interference. Rather than being directly connected to the chassis, the main circuit board inside the C-7070 is now “floating” to protect it from sources of vibration. Build quality starts from the ground up with a highly rigid, 1.6 mm-thick, fully flat chassis that provides excellent protection against shelf-borne vibrations. When it comes to parts and construction, it’s not in Onkyo’s DNA to cut any corners. Thanks to these advanced design features, the disc mechanism offers smooth and silent operation. Furthermore, the disc tray is precision-engineered from high-rigidity, die-cast aluminum. Although these DACs can process two-channel audio on a single chip, Onkyo employs separate chips for each stereo channel, to ensure the most accurate digital-to-analog conversion.Īffixed to four supports made of rigid machined brass, the C-7070’s CD drive provides excellent resistance to internal vibrations. The player incorporates two 24-bit WM8742 DACs. High-quality Wolfson digital-to-analog converters work to optimize analog audio performance on the C-7070. Separate Wolfson® 192 kHz/24-Bit DACs for L/R Channels The C-7070 uses a state-of-the-art crystal oscillator that achieves a frequency deviation of ☑0 ppm-much lower than with a conventional oscillator. The C-7070 boasts a precise clocking mechanism that controls and coordinates the timing of all digital signal processes-rather like how a conductor directs and coordinates the individual instruments of an orchestra. Super-high-frequency range, Onkyo’s DIDRC technology effectively reduces perceptible noise and delivers clearer-than-ever audio. By improving linearity and reducing distortion in the Such distortion in the super-high-frequency range can generate “beat interference”, which in turn affects the character or atmosphere of the original sound.
Despite being beyond the normal range of human hearing, frequencies above 100 kHz are susceptible to clock pulse and other forms of distortion from digital devices. To reduce this type of noise, Onkyo has developed DIDRC technology for use in our hi-fi components. However, the S/N ratio reflects static noise only, and takes no account of another type of noise that occurs as the byproduct of sound reproduction-dynamic noise. Since the advent of digital audio, signal-to-noise ratios have improved dramatically.
The three-stage dimmer function, gold-plated audio terminals, and headphone amplifier differential circuitry offer further evidence of Onkyo’s attention to detail.Īll this adds up to a player that, like your CD collection, will be around for a long time to come.ĭIDRC (Dynamic Intermodulation Distortion Reduction Circuitry) It also connects to your iPod/iPhone via the USB port, and plays music straight off a USB thumb drive.
Naturally, the C-7070 plays audio discs or CD-R/CD-RWs and your favorite MP3/WMA compilation CDs. These improvements all but eliminate noise from the source, meaning your music will sound clearer than ever. In addition, the electrical system benefits from a precision clock, a pair of Wolfson® 192 kHz/24-bit DACs-one for each channel-and Onkyo’s DIDRC (Dynamic Intermodulation Distortion Reduction Circuitry). The unit is strengthened with vibration-damping machined-brass legs, a 1.6 mm thick flat-base chassis, an aluminum CD tray with silent mechanism, a full-floating circuit board, and a handsome aluminum front panel. The C-7070 is an extremely versatile and sophisticated piece of audio equipment. It ’s difficult to imagine how you could improve the humble CD player, but Onkyo’s engineering team had plenty of inspiration.
