    DAC difference

    That's the thing though, most people don't learn to listen. In fact, the vast majority of audiophiles don't even seem to understand the basics of hearing and listening or the role of perception, let alone actually learn to listen. I have listened to what "some very creative audiophiles have...

    Headphone & Amp Impedance Questions? Find the answers here!

    It's a bit weird they would give the spec of max input signal level. Input level is defined by the USB 2.0 specification, so either a USB 2.0 DAC can easily handle that spec or it won't work. G

    1. Firstly, you seem to have missed my point: In addition to the subjective opinion that everyone has about what is loud, there's also a perceptual difference regarding decibels in significantly larger rooms and I specifically mentioned it because obviously there's a very significant difference...

    Headphone & Amp Impedance Questions? Find the answers here!

    1. You haven't accounted for absorption from the musicians, other audience members and carpets and chairs. Probably your figure isn't far wrong though, maybe a few dB less in most cases. 2. We have to be careful here, it's not a fixed point, even for the same individual! There's a perceptual...

    Digital gain (headphone DAC/amplifier) - does it affect sound?

    Ah but it's not all digital, the amp section is analogue! The reason you haven't got many responses is because we don't know exactly what's going on inside the E17. As a general rule, you would probably want the gain set to 0, unless that requires you to have the volume higher than about 50-75%...

    Should you color your DAC or your amp?

    Science knows, in addition to those of us who have done controlled tests. Anything beyond 16bit for consumer playback is hype. 1. Not that I'm aware of. A couple of things I am aware of and have used though: A. Pitchshifting, downwards obviously. B. With some modelling plugins; guitar...

    Should you color your DAC or your amp?

    I take it you don't read your own statements before posting them then? You gave us a great example in the very same post! : And if mechanical engineering were your field, you'd know about friction and the mechanics of motion. You'd know that mechanical engineering has a tolerance and that an LP...

    Should you color your DAC or your amp?

    1. Expectation and other biases can last anywhere from just a few moments to generations. 2. You don't necessarily need to own the equipment. Regardless of any marketing that implies the contrary, there has never been nor will there ever be any analogue equipment that breaks the laws of...

    Should you color your DAC or your amp?

    DACs don't set an idea as to flat. The "idea" of flat isn't an idea, it's a mathematical definition (as detailed by @VNandor). If a DAC or anything else complies with that, then it's flat and we can test that with a null test and by specifically measuring frequency response. Virtually all DACs...

    Should you color your DAC or your amp?

    1. Not in my experience, nearly all consumer amps and all studio amps are pretty flat and that's been true for many years. Even some of the more exotic audiophile amps are pretty flat. Obviously this assumes they are not being over driven and have the appropriate power/impedance for the job...

    Should you color your DAC or your amp?

    Yes, he's saying the same as I am. Fidelity requires a flat response and we want to record, store and reconstruct that recording in high fidelity (therefore with a flat response). Please note again that a flat response does NOT mean that the frequency content of what we're recording, storing or...

    Should you color your DAC or your amp?

    1. Exactly, "neutral" is an audiophile term not a scientific audio term and therefore it could mean pretty much anything anyone want's it to mean. Therefore, I could agree that the iphone is neutral and disagree that the iphone is neutral and be right both times. However, if we take "neutral" to...

    Should you color your DAC or your amp?

    Exactly, that's the difference between us. It's an art form with all manner of very specific details, informed by collectively decades of practice and knowledge, I respect that and therefore want to try and reproduce it as accurately as possible. You on the other hand what to change it, which is...

    Should you color your DAC or your amp?

    You didn't need to post it once, let alone twice! You're right though, I must be missing the point. Assuming "neutrality" means accurate (flat) frequency response, then of course you would want that across the entire audible spectrum range. And that's what you get with any half decent DAC. Jude...

    Should you color your DAC or your amp?

    1. Ah, you seem to be confused. A flat response is the objective, NOT a flat output! 2. A flat frequency response will exactly reproduce the frequencies on the recording that the musicians, mixing and mastering engineers spent days/weeks/months putting there. 3. And then you come in and change...

    Should you color your DAC or your amp?

    Your post brings up some interesting points, some are valid, some are not and just serve to re-enforce audiophile misunderstandings/falsehoods. 1. No, balance isn't subjective, it's an objective measurement. Our perceptions/preference of that objective measurement is obviously subjective...

    Should you color your DAC or your amp?

    1. Good, it's an electronic device, it obviously can't be anything but lifeless. The music and the "life" of the music is entirely defined by the music composition and the musicians/other artists who performed it and created the recording. 2. That's a contradiction! How do you make more of a...

    24bit vs 16bit, the myth exploded!

    Soundstage is a perception and therefore only exists within each individual's brain. As with most other perceptions, it can be influenced by several different actual audio properties, freq response (obviously within the audible band), phase, crosstalk, etc. The logical black hole that...

    24bit vs 16bit, the myth exploded!

    No it can't. If you are a Premium Member, the very highest quality that can be selected is AAC 256 kps. For anything uploaded by someone who isn't a premium member playback is restricted to either AAC 128 or Opus or Vorbis no higher than about 160 kbps, sample rate is typically 44.1kHz and never...

    24bit vs 16bit, the myth exploded!

    In my last response to you I stated "It has been explained to you that sound waves loose high/ultrasonic frequency over distance/time ..."and previously I stated that "what we sample is amplitude over time" so clearly I am considering the time domain and your statement is FALSE!! Again, what we...

    How does sound influence other sound systems?

    Agreed, I could have been clearer and defined what I meant by "time-domain performance" but I was trying to be brief without getting into too much detail and to be honest I didn't remember all of the specific details off the top of my head anyway, I just remembered their poor/harsh freq response...

    DSD64 Noise Issue?

    1. Yes exactly, you seem to be getting it! Vinyl adds distortion that affects the reproduction of "the texture of notes", CD does NOT add that distortion and therefore the texture of the reproduced notes is different, higher fidelity! 1a. It would be audible to bats and dolphins, not to human...

    24bit vs 16bit, the myth exploded!

    What I think is irrelevant, it's what the science proves/demonstrates that's important here and what it proves is that it is NOT random. I have no idea what you mean by the "dispatching of the elementary sinewaves in the time-domain". There are no "elementary sinewaves in the time-domain"...

    Things that can't be measured

    These "things" that can't be measured aren't "things", they're perceptions. All the audio "things" that are actually "things" can be measured. So, the science you're probably looking for is therefore Psychology, although the science of Psycho-acoustics deals with some of them. Yes, science can...

    Hydrogen Audio these days

    TBH, I see where they are coming from, although that means there's not much there of any particular interest to me personally any more. To answer your quote, millions of people use 96 or 128kbit/s, although they might not realise it; for example for voip or other applications that automatically...
