This is really funny because it shows you have no idea what you are talking about:
3. Ripple & noise are measured at 20MHz
What’s the switching frequency? What’s the audible bandwidth ripple noise you measured?This is really funny because it shows you have no idea what you are talking about:

So could you share the test protocols and structured results of some of those?I have conducted 100’s of blind tests that have proven to many people that all of the measurements used here are only just a good starting point to achieving great sound. And it’s even possible to have horrible sound from a DAC with 120dB SINAD.
Should we read this to mean that you are a DAC designer, possibly also selling such devices? If so it might be good to request from @BDWoody or @amirm to assign a 'Manufacturer' tag.For me SINAD is only a QC test. I only use it to verify if a finished design meets spec.
Sorry but you are now building an unnecessary straw-man argument. No one is saying that everyone should just buy the cheapest well-measuring DAC.I’m not selling anything here. I guess if you’re right then all of the DAC’s that Amir has measured that cost more than the $20 Meizu dongle are only for suckers. Unless you need Toslink or SPDIF input. Then $100 should get you the best possible sound with human ears.
Case closed this forum can shut down now. The holy grail of audibly has been long achieved. Be happy with what you have and take up a new hobby.
I knew I would be told I was deaf at some point in this exchange - kudos for doing it implicitly!Think of not being able to hear the difference between audio gear as a gift. One that will save lots of money. Unfortunately I’m not as gifted as some folks.
Data and names or it never happened.I have conducted 100’s of blind tests that have proven to many people
A gift would be you providing the names of two devices which measure identically (as far as human hearing is concerned) and yet where there's an audible difference which you can demonstrate a double-blind test. That would be a lot more use than your "my mum says I'm special" shtick. Golden ears only exist for sighted tests.Think of not being able to hear the difference between audio gear as a gift.

This is the one I use-The Topping E50 appears to be heavily affected by the quality of the USB power supplying it, so I've been experimenting with different 1A+ USB power supplies for it. So far I've tried a number of mostly phone chargers around the house and found one iPhone charger to be the best so far. The noisy 1A USB output on an amplifier of mine sounds the worst of all. Does anyone have any better recommendations for USB power supplies to try with it?
Ask the manufacturer. I would 100% not bother.What’s the switching frequency? What’s the audible bandwidth ripple noise you measured?
That's how Amir tested it. If you're happy with his results, I'd say you have nothing to worry about. I'm listening to the E50 + L50 playing into E-MU Wood Series Teak headphones. Playing non-MQA content (24/bit, 96 kHz rip from a DVD-Audio disc). The sound is so good that I'm probably not going to get much done today.to use the thing with non MQA coded sources/contents, would the signal stay clear from, untouched by any hardware/software associated the MQA feature? If it is not 100% untouched, would there be any remnant effects of the stuff, even on paper?

The L50 and E50 both use 1/4 inch TRS for balanced connections, so the cables I'm using to connect them are 1/4 inch TRS on both ends. These cables were included when I purchased the stack from Apos.Thank you very much. Are you using the unbalanced, or TRS to XLR balanced connections. That would be another $21 that I guess I can save since Amir's measurements show the unbalanced connections were just as good.

Apos Flow Balanced TRS Cable (Pair)
A cable built with common sense Our Apos Flow TRS cable isn’t rocket science. It doesn’t involve rare earth materials or dizzying design innovations. It simply does everything an TRS cable should. We started with four interference-rejecting cores, wrapped them in five layers of protection, and...apos.audio
That's exactly what I'm doing. Follow this link for details.Can you use the balanced connection to connect a Topping PA5 and the RCA unbalanced to a subwoofer ?
If not, is there a work-around to plug a subwoofer ?
Thank you
