A follow up of the QA-550 wave player...
QLS now has the QA660:
http://qlshifi.com/en/wzcapi/qa660.htmFeatures&Specification:
Streaming music data flow from the SD card to the digital outputs with Ultra-low jitters and high accuracy by the single threaded software framework together with 2 sets of independent sampling clock circuits (44.1K/44K) and mono-system-aspect-design in separated power supply systems and grounding systems.
Audio format supported:
- WAV : 16/24bit, 44.1~192 kHz.
- FLAC : 16/24bit, 44.1 kHz~48 kHz, compression level 0~8.
- APE : 16 bit, 44.1 kHz, compression level fast and normal.
- WAVPack : 16 bit, 44.1 kHz, compression level fast mode and high quality.
- MP3 : 16bit, 44.1/48 kHz, 96k bps~320k bps, CBR/VBR/ABR encoding.
- CUE : ANSI / UNICODE / UTF-8 Encoding.
Digital Output:(outputs can be used at the same time without interfering each other)
- I2S/IIS
- Optical
- EBU/AES
- RCA Coaxial
- BNC1 Coaxial
- BNC2 Current Mode Coaxial(needs a 75Ω ground resistor to convert the current signal to voltage signal so the DAC catches the digital input, some DACs may not have this resistor)
Support SD/SDHC/SDXC up to 128GB SDXC with FAT32 (upgradeable with further firmware upgrade)
OSD supports English, simplified Chinese and traditional Chinese.
Support Software(Firmware) Upgrade.
Output voltage: Coaxial (0.5V p-p), XLR (5V p-p balance)
Digital output formats: PCM / Dolby Digital / DTS
Total hamornic distortion: < 0.00002% @ 20-20k Hz
Dynamic Range: >140dB
S/N ratio (unweighted):>140dB
Power: 9-11W
Input Voltage: AC 110V and AC 220V selectable
Dimensions: 290x240x90mm (11.4" x 9.45" x 3.54") (with all the sockets)
Package weight: 3.6kg
Package Dimension: L440 X W300 X H130mm(17.3" x 11.8" x 5.12")
Looking at the internals, how good/bad is it? Can this I2S interface function work with my killerdac (which isn't a killerdac, but you know what i mean)...
