Extreme low-end DAC. A step up from motherboard sound but that's it.

GUTBI'd love to see the results from your double-blind test where you pick it out from DACs costing 5X as much.

GUTBIt might not be an 'extreme low-end' DAC but it is not high-end for sure. The sound is clean but flat - not too dynamic. For most people it will be a good choice. I am enjoying this DAC in general. I use it with my PC via USB. For high quality music I use a different setup anyway.

andyoYou are speaking nonsense. DACs don't make a difference in sound unless they are performing very poorly, like some Schiit DACs

euparkeriaI understand that when you are referring to a DAC you mean an audio device that contains a D/A converter chip and other circuitry. If so, then how can you say that all DACs sound the same? You realize that there are many choices when designing a DAC: sigma-delta DAC chip, multi-bit DAC chip, custom FPGA s/w, digital filter type, input receiver with signal isolation or not, asynchronous or synchronous input signal communication, clock chip quality, quality of analog output stage - solid state or tube, etc). What scientific test did you perform to come to the conclusion that all audio DACs sound the same? I am talking a real scientific test, not a statistical test. Please explain.

andyoYou can check scientific tests for various dacs, including the d30 here:
https://audiosciencereview.com/forum/index.php?forums/digital-audio-converters-dacs.10/
The topping d30 outperforms dacs many times more expensive. DACs are a very mature technology, it doesn't take much to make a completely transparent dac nowadays. Just because there are many ways to make a dac doesn't mean any of these choices translate into audible differences.

euparkeriaThis is just your opinion. Maybe you don't hear differences in audio components. But you are right about DACs being a mature technology. The website you listed is a very good reference when looking for measurements. I use it myself but it does not tell me about component sound. The assumption is that if it measures good, it sounds good. Remember, we are dealing here with two systems: audio system (A), and the human brain (B). We know about the system A a lot, but how much do we know about system B? The sound evaluation happens in system B. Do you have a scientific model of how the two systems work together? So, keep your mind open.

andyo"The assumption is that if it measures good, it sounds good. "
That's not an assumption, it's a scientific fact. Sound signals is are not magic, if they measure well they will sound as expected, there is no "good" or "bad" sound as far as dac output is concerned, only good or bad signal. All a dac needs is to measure well and be transparent (not color the sound in any way). I seriously doubt you can tell the difference between a $150 dac and a $5000 dac in a double blind test.

euparkeriaIt’s not that simple. While measuring well is incredibly important, you have to understand our lack of understanding regarding sound quality including which types of distortion cause listening fatigue and for us to perceive the sound quality as being poor.

CujobobNonsense. Audio electronics is very mature and very well understood field. There is no "magic" there, just good engineering and bad engineering. When someone designs a dac they strive to get good measurements, they don't listen to it and say "oh that sounds pretty good, lets leave it like that even if the signal does not measure as it should". Measurements is the only way to evaluate a dac, if it measures poorly then it's a poorly designed dac.

andyoAll well designed DAC's are easily audibly transparent. This is a basic fact.

euparkeriaIt is not a very mature and very well understood field. While anything audible can be measured and measurements are of extreme importance, understanding how those measurements correlates to what and how we hear is essential. Citing distortion measurements as a blanket statement is really somewhat useless when looking at quality products because distortion varies based on order. Distortion is not all created equal.

FuckHead-FiI've noticed that people pushing this DAC always cite this one review as supposed proof it's a quality product. Are you aware of the many revisions of the DAC? Of the varied capacitor brands that have been found? Some have had the wrong LEDs, many have been loose inside the case, and there have been other issues, as well.
If you can get a good one, it seems like a solid DAC, but there is some risk involved. It very much seems to suffer from being 'Made in China.'

Should I exchange the PC38X for better headphones?

I bought the PC38X headphones FOR GAMING and they are great, but I have NO use for a Microphone since I don't do competitive gaming and I was wondering if there were better headphone options at a similar price without a headphone, where (presumably) more of the cost was put into making it sound better. I also find that my PC38X don't get quite as loud as I would like and I was wondering if a cheap amp like the iFi Go link would draw a little more volume out of my phones. https://www.amazon.com/dp/B0BN6MM822?psc=1&ref=ppx_yo2ov_dt_b_product_details I went with the PC38X since it was considered the best bang for buck headphones. I care most about using spatial apps like DOlby Atmos and DTS Headphone:X. Suggestions are welcome.

Sound Signature of the Grell Project.

Wondering what type of sound signature the Drop Grell project headphones will have or trying to attain. Any update would be appreciated.

Looking for a gaming/content audio setup

Hello! I'm looking for recommendations on audio setups. I'd be planning on using it mostly for gaming. Preferably I'd like a pair of large closed back headphones since I have a big head and jaw. I'd also like to hear myself through my mic with mic monitoring. As far as budget goes, I don't really have one. But under 600$ would be nice. I can go higher if needed. The audio setup would be connected to a high performance PC. Thank you in advance for any recommendations!

$10 Drop Coupon Email not sent?

Trying to buy some gear off Drop for the first time. I was told I would receive an email with a welcome to drop $10 off promo. I never received that email. Drop was able to send me emails for my login token and email for Password update. But for some reason the $10 off coupon was never sent to me.

New here

Hello, I just joined, primarily for the audiophile products. Looking at purchasing the NHT C3 speakers for our new living room. Space is about 15 feet wide by 33 long and they will fire long ways. Space is just for general listening, music room with all equipment is downstairs, so hoping they will fill it with sound nicely. Cheers.
