30% of what? How do you compare the result you get with the one others have gotten?
Right, but in Moode do you also use the HifiBerry overlay? If so you are using the same driver as in Volumio.
Looking at your ALSA output, it seems that ALSA (or something else) is resampling down to 16 bit even though you're playing a 32bit source. I suspect that's because the driver lists max bit depth as 24 bit.
Look at /proc/asound/cardX/stream0 and see if you have S32_LE or S24_LE listed in there.
Also, can you show us a picture of the TP DAC switches? On SW1 you should have 2,3,4 and 5 on, on SW2 you should have 2 and 5-8 off.
Hi Ian,
Everything has arrived safely - can I ask about the capacitors for the IV STD - some of the values given on the schematic suggests a lot of them are 3.8nF. This is a somewhat non-standard value and given that most of them relate to HF filtering round the OP amps, I wonder if there's been a typo and they should be 3.9nF, which is a much more standard value?
Thanks again for all your hard work.
Having been an "early" adopter, I can say that the McFIFO seems to bring even more improvement than previous (extremely good) FIFOs.
Best wishes
Simon

It is really effective. The Japanese have been selling this product for 20 years.
You can buy from Taobao for cheaper one.

Upon what? There is nothing on, or within, a CD that can be magnetised or demagnetised.
You've been had, or at the very least snakeoiled
So you believe that the 99% of users who all get exactly the same result all get the wrong result, but the different result you get is somehow magically get the right one?
I know that you can hardly imagine, but this is a real fact, and you only need to know it when you actually try it. I deceive everyone, it is not good for me, because this CD drive is not sold by me.
What you said seems to make sense. It seems that I have to buy a PI to try it again.
I found that I can play normally mp3 or WEB RADIO without resampling. This seems to mean that my problem is not in the DAC, the problem is that my PI can't directly handle higher high resolution WAV files?
SW1 and SW2 of my TP DAC is the same you said.
I think you and I have a very different definition of the word "fact". I think your usage is more close to the word "belief".
The fact that someone is selling something is no proof that the product actually works. People have also been selling homeopathic "medicines" for hundreds of years. That doesn't mean that they have any effect beyond the placebo effect.

If you really want to know the theory, you can google it yourself. If you just don’t believe it, but you’re too lazy to actually try it, you can skip it.
Ever heard of the concepts "burden of proof" and "extraordinary claims require extraordinary evidence"?
I have no obligation to let everyone believe what I am talking about. Furthermore, according to your tone, even if I find a lot of relevant theories and patents, you will still use a lot of arguments to refute. However, why should I waste my time talking to someone who doesn't really want to know?
Anyway, I continue to use it happily after I actually use effective means to improve the sound quality. A lot of things you talk about will not hinder my happiness.

I can't find /proc/asound/cardX/stream0. Can you explain more clearly? In /proc/asound/card1/ is only pcm0p.
Indeed. And we have no obligation to take your claims seriously.
I definitely do want to *know* - as opposed to believe.

Yes, believers will continue to believe, no matter what the actual facts and evidence are. If that is what makes you happy, then good for you - but some of us prefer a fact-based approach.
I can execute normally: aplay -D plughw:1,0 5.wav -v, where 5.wav is 16bits bit depth and 44.1KHz.
When I execute "aplay -D plughw:1,0 6.wav -v", where 6.wav is 24bits bit depth and 352.8KHz, the system displays:
