For sure I won't use it as a measurement device...https://www.l7audiolab.com/f/ifi-gryphon/

Remember my ears might have deceived me. But, for me, it is a really good equipment. If I’d have it before the Topping E50, maybe my opinion could be diferent.HOW? There is no review on ifi.
If sounds "smoother" then is NOT transparent.
to be crystal clear: non transparent device can be enjoayble, the "extreme" example i've in mind are guitar amplifiers where most people love lamps _BECAUSE_ they are not transparent... IMHO a hifi device must be transparent (as in "high fidelity") because some colorations sound great for one kind of music and not for another. If your sound system is transparent, you can then choose which effect to add in a controlled manner and not the one the manufacturer had choose.Remember my ears might have deceived me.

But the main point is your enjoying your music after all !

Thank you for your very rapid response.I don't think it's a problem with Topping E50.
The first thing you should do in order to investigate the problem is to connect it to another PC and see how it works.
In order to operate the Topping E50, it is necessary to always supply 5V power.
Therefore, please do not turn off the E50's 5V power supply even if the PC power is turned off.
Oh, and I need to mention that the 60 seconds is absolutely a "feature" that is intentionally built into the E50's firmware.I don't think it's a problem with Topping E50.

The E50, like a TV, requires a minimum power supply for its automatic features to work.
The 60 seconds of idle time mentioned in the question seems to be due to the settings on your PC side, not on the E50 side.
There is no misunderstanding.There seems to be a discrepancy in understanding. I use two E50s along with three different Windows 11 PCs and I don't see any of the behaviors you claim. In fact, if the PC is turned off and communication is interrupted, the E50 will go into sleep mode after 1 minute based on the firmware settings. When you restart your PC, communication will be restored and the E50 will wake up and start working. If the E50 goes into sleep mode while the PC is booting, this is an issue caused by a setting that stops communication if there is no active processing on the PC side.
Yes..!I have a similar issue with my E50.
I am using Roon and Ropieee endpoint.
After entering standby, first attempt to play something from Roon gave me an error, the device could not be found.
I have to wait a few seconds for the E50 to become available and after that starts playing at second attempt.
So, I think there is a firmware problem but Topping doesn't care about that.
The solution (which I proposed to them in detail) is simply to power up in an "active" or "on" state when in the A-C setting mode and stay that way (see below).So, it seems that is not related to a specific OS or audio player.
Your experience confirm that. Anyways, I will try to do another test, using also another audio player distro to fully confirm that.
In my opinion, this is a poor implementation of the standby feature in the firmware that could probably be solved easily by Topping.
I am surprised by the lack of reaction of Topping, even after I've send them an e-mail about that issue.
I think this is a problem that can be easily reproduced without asking about a ton of details !
Maybe, somebody will read our complains and I hope there will be a firmware update for E50, or at least a statement that this is normal from Topping point of view and nothing could be done !
ToppingE50's operation is very functional and I like it. But you don't seem to like the E50's behavior. I think the only way to solve the problem is to decode the firmware and rewrite the program yourself. Or you can replace it with another company's product such as SMSL.The solution (which I proposed to them in detail) is simply to power up in an "active" or "on" state when in the A-C setting mode and stay that way (see below).
Then because the A-C mode defeats the timeout timer it will remain active at all times until the DC power is removed.
Does it not make logical sense that if a user has chosen to defeat the timer that they would also want the until to power up in an active state?
The problem is very easily reproduced and you do not even need to plug the DAC's USB connection into anything to show it.
This also proves beyond doubt that the problem is in the E50 and not the fault of any streaming device.
Try this please-
I verified this once again just now, and even after 10 minutes of no-USB-cable operation it remained "active".
- Set the mode to A-C.
- Disconnect the USB cable and power it on.
- It will appear to very briefly power up into the "active" state (brighter pilot light at the bottom right of the display).
- However within about half a second it goes into a standby state (dimmer light) and will remain that way until you touch the front panel button.
- After touching the button to wake it up it will remain on (active state) for as long as you care to wait until you either touch and hold the button again or remove the DC power.
However, I still had to manually turn it on as described above.
I sent Topping several emails about the problem too.
Their final response was more or less: "go away".
I spent my career developing industrial control hardware and software (I am retired now).
I know where I would start looking for a solution if I had access to the source code.
My best guess (I could be wrong) would be that the timeout timer is either uninitialized or improperly set to too large a value during power up.
So it triggers the timeout function the first time it is tested, even if the A-C mode is selected.
Then after that they are probably either continuously resetting the timer or defeating the timeout testing function (in the A-C mode only).
But by then it is too late and the unit has gone into standby mode.
The solution would be to reset the timer value immediately during the boot up code before it is tested for the first time whenever it is set to A-C mode.
In A-O (timeout) mode, do nothing, it does not matter because it will time out anyway.
The solution could come down to merely one or two lines of code in the power-up sequence.
Yes, this is a poor implementation and a genuine bug.
But what do I know?.

Thank you for your opinion. I am glad to see you like the functionality of E50. It is indeed a good product. Unfortunately, like @DIYguy also said, there are things that could, and must be improved in my (and not only) opinion.ToppingE50's operation is very functional and I like it.
