No need to take things so personally. It's not like there's 140 pages on this topic already....
https://www.audiosciencereview.com/...e-as-transparent-are-that-many-confused.9245/

"Transparency is just a small part of the equation" really needs some explanation though, feel free to make a new thread and convince us of your vision :p

Because if a device is 100% transparent it doesn't need to sound pleasing... pleasing sound and technical capabilities can be two different things. I'm not an analog vinyl fan.. but thousands of people swear by it. They prefer how it sounds over the digital new stuff... I personally don't think so. But they do. My post was just about that part. Do I like what I hear. Yes I do. And disclaimer states clearly it's a subjective point of view and can be used as wished. Not to state that it IS like that. It's how I experienced it. I really don't see why someone should come in and start the endless debate about that once more...

Unless you say that people can't have different preferences anymore... That would sound like this forum is more of a dictatorship than anything else? I think that's not what Amir means also.

No I saw your disclaimer and it's fair game if you say it's just your subjective opinion. Some could argue it gets off topic when it starts to challenge beliefs; IMO technicalities and pleasing sound should overlap. I'm aware of vinyl and its myths, same thing for tubes, but we are talking DACs. Technology in D/A conversion really is a solved thing. I'm not aware of anything that is missing in current measurements that does not show underlying sound properties. Take for example "warm" vs "bright", simple FR measurement showing none such thing means it is really just conviction or imagination. You can't claim brightness (for example) if no frequency shows up to be elevated...

Anyway enough from me. If you have concrete questions I do encourage you to make a topic rather than discuss here. Yes, some "measurement police" critics will surely show up but I don't see why one can't have a polite discussion. Like I said just try and not take things too personal, this is ASR people have a habit to challenge statements like "measurements don't show/explain everything". If you could prove that, now that would be game changing.. ;)

Just received mine. Sounds really neutral, I'd say it struck me as "dark" sounding at first, but considering that I'm coming from an Audient id22, I'd wager the difference is probably just due to lower distortion in the highs. Not a night and day difference (as modern DACs generally don't sound worlds apart nowadays), but I feel that transients are slightly more discernible and there's a sense of effortlessness to the sound of the D30 Pro. The Audient feels a little bit rounded out for lack of a better description.

All in all, the differences are rather small, but it definitely feels more neutral than my old trusty interface as far as DA goes. Then again, the id22 is like an 8-year-old design, so comparing the D30 Pro sonically to a more modern, high-performance DAC must be an exercise in futility. I kinda bought it for the peace-of-mind factor, though, so I'm happy. DAC obsession done and over with as far as I'm concerned.

I confess, I'm a sucker for the Orange display and cockpit quality toggle switches. They've landed on good sounding stuff with a classic industrial design that just looks good on my desk. The only thing that might make me want to upgrade is a new model with orange backlit VU meters:)

I just got mine two days ago, and so far so good with everything, however I’m having an issue. I’m not sure why but after like 6 hours of being on I hear static or crackling when the unit isn’t playing music. So far it’s been via headphones by the time so much time has elapsed. I have yet to try what it sounds like on speakers.

I do most my listening at night.

Any idea why this is happening? It actually kind of sounds worse than my hybrid tube amp. Obviously that is a direct result from the tube.

The unit isn’t getting hot either. I just tried again today with a different amp to see if it’s an amp factor. Never heard this before out of either amp.

Bad unit maybe?

I had a similar problem some years ago and in this case was the tube amp. The tubes were pretty sensitive to EMI/RFI. If my mobile received a sms the amplifier would do some weird noises or I put my notebook close to it and among other things...

Yes, tubes I believe there are two things that cause sound. But there are no tubes in this so I’m not sure what’s going on.

leave the dac/amp on and reboot your computer or unplug/plug back in your device feeding the dac, see if it goes away. I've had some signal related issues, software related.

Yes, I will try that, but at the beginning there’s no sound at all. It’s completely silent. Just seems like after it heats up internally something is going on and the unit isn’t really getting hot. I will try with my streamer today as the source. See if the samd issue will persist

for me its happened twice after pausing a stream for long period of time with everything left on

Yea that’s probably causing the unit to heat up and mine is excessive use cause I’m not leaving it idle.

No, it was software. I just closed the browser and restarted the stream and everything was good. Had nothing to do with the headphone.

I don’t use my web browser, I use the Quboz app

Try killing the app when problem is occurring, then playing a different app
Hmmmmm I will try, but you would find it odd out of the combination of dacs and amps I have for headphones specifically, about 8, to now this and I have never had this issue.

So it just seems kind of odd.

Hey Guys,

i use the D30Pro and connect the RCA's to my stereo AMP. However, the stereo AMP states a sensitivity of 0,55Vrms on the AUX and the D30Pro gives 2Vrms. Is this a problem? I already connected this and found if i turn down the D30Pro to -5 my AMP has to go to 0Db which is kinda ridiculous because -10 to -15Db on my AMP is enough on other sources.

Any thoughts, tips??

What amp are you using? What were you using before?

Hey MacCali,

it's an Elipson MC MK1, https://pdf.archiexpo.com/pdf/elipson/music-center/91474-284769.html using D-Class ICE by B&O for amplifying. This is my first DAC (converting my ROON ROCK NUC). Before i had similar function from Auralic Aries Mini, also 2Vrms.
Hmmmm honestly no clue, this is probably more towards someone more professional. The only thing I can think of is the attenuation; maybe spelling that wrong. But the aries mini may have greater attenuation.

When using on headphones I actually noticed I am getting more volume at lower gain settings on the amp. So I am experiencing the complete opposite of what you are, then again this is a headphone amp.

Hopefully someone gets back to you with a more precise response. That would be the only thing that comes to my mind as there are many variables when it comes to audio.
