Yes indeed..!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.
There are indeed always another options, but we are not talking here about that !
We are talking about a product that we bought and are using it, not about something we can buy.
So, I think Topping must know if there are also some complains about their products, not only appreciations !
Regarding the firmware, if Topping does not want or have no interest in developing an improved firmware, maybe could provide the source code and that could be a solution for us, the small community of unhappy people.
I completely understand that once a product is released, unless there is a glaring problem, a manufacturer would be hesitant to change it in any manner.
However as you said, you and I are not the only ones that have voiced similar complaints about the E50.
If by some miracle Topping would release the source code (which is vanishingly unlikely), I would be the first person to dig into it and fix the issue I am having with it.
However, to reverse engineer firmware from compiled code can be extremely difficult and time-consuming, therefore unlikely to be worth the effort.
I would very gladly sign a non-disclosure agreement just to be able to work from the source code, if necessary.
But I certainly will not hold my breath waiting for this to happen.
In the meantime, their customer service department did just now respond to me that the D10s may possibly meet my needs.
Because I do not need or use the balanced outputs on the E50 their absence on the D10s would be of no concern to me.
I should receive my new DAC in 2-3 days (however I am still not saying what it is) and will test it every way I can think of then.
I will post the results, good, bad or ugly.
I totally agree with you that this forum thread is not about what could be purchased, it is about what we already purchased and are using.
However, if a suitable "solution" is available for those having problems with the E50, it might help them to purchase a different model than the E50.
