• Same old story – a whole new performance…the C10 Digital to Analog Converter In many ways, the guiding principles that underpin the C10’s design are firmly rooted in the existing 1 Series. But the revised topology, the novel DSQ™ Phase Array DAC architecture, and the incredibly sophisticated grounding and power supply arrangements deliver a whole new level of upgradable, configurable, musical performance. The 16 software-driven R2R DACs at the heart of the C10 mean that it is both updatable and future-proof: as future-proof as the C1.2 – still at the top of its game after 15 years. The C10 establishes a completely new standard for musical performance, practicality, and versatility. It promises its owners a relationship that’s as long as it is musically rewarding. The C10 relies on the proven performance of the PCM 1704 R2R DAC chip, driven by our sophisticated DSP-based, short-tailed PEtER over-sampling algorithm. The DSP operates at a 32-bit fixed point before conversion to 24-bit at the output, the native resolution of the PCM 1704. The C10 uses 16 DACs in a dual differential, sequential DSQ™ Phase Array topology. The C10 power supply provides four independent, highly regulated multiple DC feeds to galvanically isolated circuit blocks within the chassis: the digital processing circuitry, the clock, and the left and right DACs. The audio chassis has adopted a mirror imaged layout, the modular input cards located centrally with the DACs disposed on either side and benefiting from symmetrical clock feeds. This pure DAC is dedicated to delivering the best possible performance from digital storage media. Best performance demands pairing it with a top-flight line-stage pre-amplifier, like the L10. To optimize system matching, it offers user-selectable output levels (1, 2.5, or 5V) and switchable local/global feedback. Inputs are still modular and configurable. The C10 is fitted with CH-Digital-IN HD and Ethernet Control cards as standard, providing connection to CH-LINK HD, AES/EBU (XLR), S/PDIF (RCA), and TosLink optical inputs and also allowing network control via the CH-Control App. The Ethernet Control card can be upgraded to the Ethernet-In HD card, creating a high-quality streaming interface (compatible with all major streaming services). Three additional slots allow users to fit an extra digital input card, a USB input, and the Clock Sync card for connection to an external 10MHz master clock, such as the CH T10 Time reference. The C10 Mono To move from the C10 to the C10 Mono, you simply add an extra power supply. The separation of the circuit blocks within the C10 audio chassis, combined with the four discrete DC feeds from the power supply means that we can surpass the benefits of the six-box topology by adding a single extra power supply chassis, splitting the DC feeds between them. Same significant step up in performance – half the boxes to accommodate. C10 Digital to Analog Converter: Processing:

    • Multiple cascaded discrete linear regulators.
    • Shunt topology regulators for critical stages.
    • Independent left, right, clock, and digital grounds.
  • Of course, it is digital conversion that lies at the heart of the C1.2. The perfect preservation of time and amplitude information is critical to reproducing musical signals stored in digital formats and we believe that the advances incorporated in the C1.2 build significantly on the solutions adopted in the C1, taking digital performance(s) to a whole new level. Both noise and jitter are central to the design of any high-performance DAC. We have developed an entirely new MEMS-based, shunt regulated and thermally compensated clock for the C1.2, improving clock accuracy significantly (as well as providing highly developed clock-sync and external reference clock options). A four-fold increase in processing power has allowed us to further refine the proprietary CH-PEtER algorithms, introduce 32-bit fixed point processing and increase input compatibility to include all high-resolution digital formats, whether from optical or file replay sources. Our proprietary CH-Link HD interconnection allows the transfer of native DSD and MQA data in the digital domain, from the D1.5 transport to the C1.2. The AES/EBU and S/PDIF inputs accept PCM at up to 192kHz/24bit resolution, while the HD streaming input will accept PCM data at up to 768kHz/32 bit resolution and DSD512(8x). Local regulation of the DSP and FGPA further reduce the system noise floor. The DAC itself employs no fewer than four converter chips per channel, in a fully differential, dual-mono topology. The vital analog output stage is discrete, fully differential, Class-A and DC coupled. The modular input architecture ensures that the C1.2 remains future proof, able to adapt to changing digital standards or system demands.

    Boulder 508 – Trade-In

    Original price was: $5,000.00.Current price is: $3,000.00.
    The 508 was purchased new and well cared for. This phono carries the DNA from the Boulder 2008, making it an exceptionally efficient product in a much smaller package. I know the sonic characteristics of the Boulder 508 very well, and it captures the Boulder clean and accurate sound without sounding too clinical. The settings are internal and locked, and cannot be configured. Output impedance is 100 ohms, and gain is at 70 dB, which easily handles most cartridges on the market. Trades may be considered. Shipping will occur once the funds have cleared. All demos and trade-in sales are final.

    Bocchino XLR Mayflower – Floor Demo

    Original price was: $3,070.00.Current price is: $1,000.00.
    About Bocchino: based in Australia, Carmine Bocchino runs and operates a boutique business focusing on quality constructed cable terminations and related products for signal and power. The Bocchino Bocctech brand ready-made cables offered here incorporate the sum of the parts as a whole; Mayflower uses copper conductors, making things a touch warmer, All terminations and plugs use UHM polymers for resonance with copper metallurgy, IME terminations have some serious weight on cable performance. Bocchino terminations are designed large in diameter/size, so inputs or outputs need at least 1/4" space between them and do take note of the photo with the ruler to understand the length so have enough rear clearance. These cables are about 3 years old and have been used and the jacket is beyond durable making this one quality cable. All Bocchino is priced to sell as the brand is not widespread in the US, making these high quality cables a financial loss for AU. Note: Carmine builds cables and not boxes, so no OEM boxes with cable. Prices for Moonsoon has sold, and there is only 1 pair of 2M Mayflower's available.

    Retail prices are not sale prices; please call to see what we can do to help you get these products into your system. Trades may be considered. The product will ship insured and, in many cases, palletized by ground carrier.  Shipping will occur once the funds have cleared. The product is not under warranty unless stated. All demos, trade-ins, and open boxes other than new, non-special ordered sales are final.
