Setting aside your hifi journey and repair experience. The “I don’t have a clue what I’m talking about” is clearly offensive to me. Interesting that you don’t see that. But we have disagreed in the past, so no surprise.
you are right, that is not an agreeable thing to say. But not everybody is always equally well-spoken or feeling at ease atm. Try not to take it personally. When you are tired or anxious (as many are in a lockdown) it is not that clear cut or easy to write flawless English, especially if its a foreign language to you. You might want to take that into consideration before you feel you must slap somebody on the wrist. And when you do... better not make mistakes or you will look rather silly. I notice this many times that (often) Americans are not very understanding, appreciative or patient when others are trying to express themselves in
your language. And I'm not even speaking about diffetence in culture. Where I'm from, we don't beat around the bush and come straight to the point.
We don't always disagree. I think we agree more often than disagree, but difference focuses the dialog on the disagreement to get to a fine understanding on the matter. That is why we post here, to share information and learn. When everybody says the same thing there is nothing to learn (unless you have blank spots).
What is also a common sentiment in America, and something that irritates non-americans is their xenofobia disguised as patriottism. And on that bombshell... No, i can't walk away on that. It's good to be proud of your country (something that we, the dutch, lack very much) and the things you make. But so are other people. It is hard to apreciate something made in a country of which your media is constantly bombarding you with propaganda of animosity, hostile intent, scandals, stealing jobs, communism... yada yada yada. I am with a starting business in bamboo we get from a Chinese distributer. I can tell you, there's a big difference in culture that can't be 'google translate'- ed. You need a lot of patience and empathy to do business. But when you do it is very worthwhile. You can't keep thinking that only American is best and that anything sent from outside is a risk, dangerous, bad or inferior.
Especially China is the largest, fastest growing economy with the largest number of engineers and graduates per annum. The world is changing. And it is said intelligence is the capability to adapt to change. So let's help eachother with that. (that's what I'm trying in my own socially awkward way)
PS 1:
what Lolito said:lack of schematics. I can attest to that, and understand it very well. Given the the whole 'Musician Pegasus ripp-off thread', and culture of copying /lack of copyright in China you won't be seeing one soon. I've been thinking of modifications to the Ares, but I'm not risking it with these small smd components and without schematic. The Ares still sound fine 'as is'. Only the coax sounds a bit too 'rounded', rolled off to me. But only from CD as a source via coax. So i use my old NOS R2R for that to get more openness and raw energy. CD's are often problematic anyway given the mastering practices of the post 90-ies.
PS 2:
On 'relativism'; while the dac is part of a system, it doesn't change anything about how the dac is set up on the inside. The dac itself is a system. So we are comparing one system of input preparation, power supply, conversion and outlut stage against another, different system of DAC. So if you change the output stage only, it is like saying you changed the amplifier, or the speakers, or the room or... See where this goes? Following your logic we are already talking about a system, so let's stick to the system inside the box.
If you want to embrace relativism you say; "we're all part of the universe. The whole universe is changing". Sure, but we are talking about this particular object and how it performs in different settings. Some properties are set to perform within predefined parameters called standards. Like output impedance. That gives you a choice to make about the output stage. Do you want versatility (that most people dont need) on the outside by using extra components on the inside at the cost of signal integrity. Or do you single-mindedly chose to keep signal integrity? Minimalism: make it close to perfect for its intended purpose only.
That choice reflects on what is inside the box: the boundary of the object of our discussion.
