Alas your unfounded and misplaced (as usual), but luckily for me I don’t owe you an explanation, especially if your suspicions and criticism are purely based on your lack of understanding or misinterpretation of what I say. But I’m always happy to help you with the answers, so here we go! 1. Find my post with the photo of T1 PCB that has two red arrows in it. Note the frequency printed on the components they point at and compare to the frequencies of oscillators I posted. Then research why those two frequencies are used for DACs and how. Post your findings here clearing me of your misplaced suspicions. 2. Find out the name of Allwinner CPU from the same photo. Google its darasheet and find out what clock frequency it usually uses, compare to photos of PCBs that use same CPU, compare to T1. Post your findings here clearing me of your misplaced suspicions. 3. Create of find schematics of DSD Pro and T1’s output stages, note how specifically they are different (hint: there is a difference indeed, a clue is 22 - 10) Post your findings here. 4. Find, re-read and quote my post directly using forum’s quote function, where I allegedly say that (I quote you) “you must remove the resistance or lower them” (sic!) asking for clarification of what I mean and if it the case in the mod photo I posted. Asking nicely would help, but not necessary. 5. Research BJT transistors and double check if they are digital (or could even be digital). Post your findings here. 6. When using phrases like “ It doesn’t appear to be the case based on the pic you posted.“ it is beneficial to use complete sentence, adding “to me” after “It does not appear “. This helps to aim the vector at the true source of mistakes and errors, helping to address and fix them. As long as you follow at least 5 out of 6 above I’ll be fine.
