APL Hi-Fi DSD-SR :
The DSD-SR is based on a modular design, allowing a cost-effective future upgradability of any internal stage.
- Proprietary asynchronous USB input module accepting DSD64 and DSD128, as well as PCM rates up to 384kHz/32bit.
- Proprietary PCM to DSD converter module with DSD64 and DSD128 capabilities, user selectable from the remote.
- S/PDIF digital input module accepting up to 192kHz/24bit PCM.
- All PCM rates from USB and S/PDIF sources are processed to DSD domain, prior to D/A conversion.
- Pure DSD Digital to Analog conversion module.
- Paralleled Flagship DAC devices working in DSD only and a special mode we have developed, resulting in much improved audio quality.
- Ultra-low-jitter Femto Master Clocks.
- Proprietary DTR input intended for connecting our DTR-MR digital audio transport.
- Pure Class A, unity-gain Single Ended MOSFET output stage.
- Unique Hybrid-Attenuator offering a lossless volume control with 0.5dB step, negating the need of a preamplifier, wherever possible.
- Passive DSD analog filtering and interstage coupling, featuring custom Lundahl audio transformers.
- Zero Negative Feedback design for the MOSFET output stage.
- No capacitors on the signal path.
- No mechanical contacts, relays or switches on the signal path.
- Solid core Oxygen Free Copper internal signal wiring.
- Oversized Custom P-Core balanced main power transformer.
- Optically controlled, mechanical-contacts-free devices for main power switching control.
- Delayed start for proper warm-up.
- High grade, specially selected rectifiers and passive components.
- Solid Copper wiring for power supply.
- FLD display with custom selectable Rose, Blue or Green colors. Please specify when ordering.
- Microprocessor control memorizing last settings, including volume level for each input.
- Infrared Remote milled from solid Aluminum blocks.
- All-Aluminum, precision machined enclosure.
2-years warranty with an available 3-year warranty extension, with an online product registration. Please visit http://aplhifi.com/register/
