Hi, How to be sure the DAC consumes power from power input rather than from USB data input? I don't see any indicator on the display.

Ok, have bought it. Haven't noticed any (sub)bass degradation. 0.3 Ohm cable is in use. Have measured BTR7 Zout on 30 Hz and 1 KHz (27 Ohm load), It is the same and is about 1.02 Ohm (SE). Overall impression is Ok, probably plenty of LDOs are not just marketing, but help to keep macro-dynamic...

Yes, DD Zload could be almost flat. But the thing is, on very low frequencies this electrical + mechanical + acoustics system (that is a bud and an ear) is far from being more or less linear system. To my subjective feeling this non-linearity nature depends on source Zout. And again, I haven't...

Thanks for sharing, so output impedance is at least sufficiently small to not be noticeable without special focusing on sub-bass. What is your IEMs impedance? the thing is my main (flat head) earbuds are 16 Ohm only. As for Qudelix - I have measured it, and, as far as I remember, Zout is about...

Hi. Time is going... Has anybody noticed any drawbacks of not-too-low BTR7 output impedance? (slight sub-bass blureing or... what?) Of course, the question is more appropriate for owners of low impedance earbuds. To my taste output impedance measurement (as a function of frequency, for a couple...

Jazz (mostly of 50-60) is one of the main (Classical is the next) my favorite genre. And complicated harmony isn't that factor attracting me (as we see in video). I'd say a rhythm (soloist dancing around main bit) is the most attractive, and notes intonation is the next.

Then only obvious differences can be accepted for sure, I guess.

Sorry, not sure how to have an impression on blind testing. The aim of blind testing is to get knowledge.

Is seems to be cars fans forum now.

Sorry, I guessed those issues details are in your memory, and you mean some technical conclusion.

Are ones the same? Similar to PA5 defect? Or just inappropriate using?

It depends on the final sensitivity of this mid-high section (including xover).

Really. Especially with 60W as max for the driver.

Your one does. Happy music listening.

Your extrapolations about what I mean indeed are just your fantasies. I mean exactly what I have wrote. Nobody without own ABXing experience is able to really understand that state. Those avoiding ABX are just happy to live in their "golden ear" world. It is great to be happy.

Any ABX experience results in healthy (and somewhat dramatic sometimes) mind shift. Then you start to distinguish mind-focus-based guessing and facts.

Sure, 99‰ it is the case.

ABX? By the way, sometimes "more details" feeling could be a result of dirty HF (being dirty it attracts attention).

All my own amps/schematics work from 0Hz (that is without capacitor in signal path). If this is the same case, why not?

Have not noticed any signs there the caps are in signal path.
