This depends on the DAC, but most modern DACs re-clock the signal, and so are fairly immune to the details of clock quality.
Ok, I’m just trying to figure out if when using the device as a streamer only as in passthrough to my pre/pro it even uses any of the clocks on the device at all? Sorry maybe I wasn’t explaining my use case clearly enough.
For the analogue out it will use the updated internal clock. it will also use the updated internal clock for SPDIF as the sender is master clock. A better clocked signal means less for DAC to fix. HDMI will use separate clock system as it works differently to the audio only pipeline as its tied to video.
So for HDMI:
Stream >> Eversolo A6 >>HDMI >> Marantz AV10 >> Amps >> Speakers
I understand it won’t use the DAC on the A6 but it will use the DACs on the Marantz.
But it does still use certain clocks on the A6 for this use case?
Deciding on A6 Gen2 or A6 master edition Gen (which has upgraded clocks/opamps), but if those components aren’t used then it might be a waste of $$.
Yes HDMI need clocking its just uses different ones as its a different rate for HDMI as its derived from video, the ones updated are for Audio. The updated op amps are only of use for analogue out using the devices DAC they have no part in the Digital chain.
This is from the product description:
Ultra-Low Jitter Femtosecond Clock Synchronization Management
The clock system has been upgraded with ultra-low noise jitter, making digital audio signals even purer. The combination of ultra-low noise jitter clock oscillators and optimized algorithms reduces clock jitter to an extremely low level, ensuring stable rhythm and pure tonal quality in the music.
Does this look like it would be involved in the digital HDMI signal?
I’m sure I’m over thinking this,
HDMI relies on Video clock not audio clocks it was never designed purely for audio as it requires a video signal to be sent along with it. The important clock for HDMI its at the receiver end where the DAC is and this derives the clock from the incoming signal and will reclock it as best it can. HDMI is noted as not being a great connection for Digital Audio due to its high jitter and noisy components. Same receiver can have very different results for nasties when receiving audio from SPDIF via HDMI.
I’m not sure how the A6 is transporting the digital signal. There isn’t any video involved just audio. It’s the only way to transport multi-channel (5.1) music on these units.
Read the Oppo article about HDMI on this post. Same principle applies to any HDMi device . HDMi uses its own Video clock at very different frequencies to what the clocks for audio are and are the ones they go on about.
Interesting. With that said then I started thinking about Blu-Ray HDMI connection to my pre/pro. I never noticed any issues.
The Marantz AV10, while generally regarded as a high-quality AV processor, can experience HDMI jitter issues, particularly when connected to certain devices or with specific HDMI cables.
- Jitter
refers to variations in the timing of the digital signal transmitted over the HDMI cable, which can lead to audio or video glitches, such as audio dropouts, lip-sync issues, or video artifacts.
So if HDMI is not used, would coax or toslink be recommended for digital?
Use what you prefer thats all that matters. Was just explaining the better clocks in the A6 offer nothing for HDMI and multichannel. I would myself use the Coax, but in the end its up to you and what works best for your situation.
Ok, yea I agree coax although susceptible to noise does carry more bandwidth then optical.
Thanks for the input.
I see they’re adding Wake On LAN - should have been there to begin with. I must admit I was rather surprised and disappointed when I realised it was absent on my Gen 1.
