We are working on a workaround to enable double tap wake up, this is a work in progress, please be patient if you are looking forward to this feature, it won't be long.

Saw the 8-series stack right besides the HA-2A, so I guess you have dropped by our Munich high-end booth and have checked out new products as well. I hope you are impressed by the new products as well. I assume there is a set of HA-3A somewhere in the booth, or it wasn't hooked up but in...

If that's the actual signal flow, the headphone output will also bypass the potentiometer. The flows with three arrowheads are signal control circuit. To follow the audio signal, follow the regular single arrowhead path.

While I can think of several possibilities to explain or test regarding your distortion problem after you crank up the volume to 3 pm, none of them can explain why it was OK in the past and the distortion shows up suddenly, especially when you have assured that nothing has changed in between...

Thanks for the lead, I'll check this out when we have a review sample available. :beerchug:

Sorry, what is PCA? You are connecting the Holo May to HA-300MK2 via RCA, normally RCA line out is around 2V, maybe 2.2V, 2.9V is considered a fairly hot RCA line output IMO. This falls in line with the input sensitivity issue that I described previously. The Vio 590 is a DAC/Amp? Have you...

I was concerned when he said, "With a further increase in volume, distortion increases, but the volume almost does not increase." This sounds like an input sensitivity issue to me, in other words, his input level is too high, forcing the amplifier to reach the maximum rated output at the 3...

Can you describe your complete audio chain? from DAC to headphones? I assume you didn't change anything upstream when you changed the 6SN7GT to Melz 6H8C (when you noticed the problem)?

The memory management of Android systems has always been their weak point as they are not a truly multi-tasking system. If you run get stuck in the middle of an OTA update, you need to clear the cache of the system update process otherwise it will repeat the download error: Disconnect your...

Separating the high-voltage and low-voltage will reduce the ripple effect from interference, internal as well as external. Clean power requires attention to detail.

I sure hope so, but we are still months away from a marketable product, and finding a good reviewer with appropriate traffic and profile to cover this amplifier would be difficult. That is understandable because sending a massive amplifier like this back to Zhuhai after the review process will...

When the amplifier is very transparent, yes. :beerchug:

These two diagrams explain the main functions and input/output interface of Soul 170HA. We'll explain the features and design considerations in detail later, but I would like to highlight the power connection between the Amplifier chassis and the external Power Unit. Unlike the...
