  2. Chris, you keep reality out of this...
  3. Those are the good, minimum specs that are needed for reasonable judgements. Hobby claims need that kind of characterization also (perhaps to a bit less detail just because of practicality.) I am also skeptical of the effects of the input transducers. I haven't seen the full specs recently -- but for those still into vinyl -- the impedance thing, esp for MM is important. Since MM/MC preamps are common in the hobby realm, claims about distortion really need to include the impedance of the transducer. But yep -- this is getting into the realm of relatively meaningful. It WOULD be nice if a transparent explanation would be given for non-techie audiophiles also -- what does that 0.001% mean if it increase to 0.01% at 30kHz? You know what I mean... IMD is also important, where THD vs IMD have different importance at different frequency. To do the specs in full detail can be onerous. But, it isn't about the 'specs' per se... Like, how bad is the IMD. Is IMD even an issue in the design (it can be an issue, but hopefully a good design won't make it worse than what it should be.) I can keep on rambling on about this without communicating more of what I intended -- but as we all know (both people who have a preference for objective or subjective), raw numbers are meaningless unless the *effect* of those 'numbers' (however diminishingly small or big) on the sound is the important thing. I'll sign off on this subject because my point is made -- and I only feel uncomfortable when being too much or too little focused on the objective specs, and also uncomfortable if the subjective effects aren't verified/tested. When I suggest 'testing', I mean using experiments with controls. These true subjective tests, with some reasonable scientific/statistical/blind method are very inconvenient, but can be amazingly beneficial to both the consumer and the engineer doing a design. For the design, it is more about verification, but for the consumer, it can be about validation or choice. (probably other reasons.) I guess -- I try to say, don't discount ANY information source, and use whatever tools you can make available. Doing things 'right' can be incredibly inconvenient, and happily, much of the time, we are lucky -- and HOPEFULLY whatever mistakes we make in design/testing and as a customer end up being inconsequential. (To be polite, unless someone directly replies and effectively asks for response, I'll just lurk again :-)). John

  9. I don't know about your specific Asus motherboard, but most mic inputs in motherboards are mono. Also, a mic input, as opposed to a line input, expects a low voltage level. If your motherboard has a line-level input (which btw always are stereo), then your best chance is to connect a tape output from the Denon to this line-level input in your motherboard. If your motherboard doesn't have a line input, your best chance is something like the Nad device mentioned in a previous post, directly connected to the PC via USB. Note: some old mac computers had analog, line-level inputs. Also, even cheap USB soundblasters have line inputs. Finally, I think there is a cheap Behringer usb device with rca, phono-level inputs, very similar to the Nad. Regards, Jorge
  10. Although my main interests are classical and jazz, I try to keep an eye on pop/rock. So once in a while I buy a few music magazines, I poor myself a good pint (a La Trappe Quadrupel this evening 😛) and browse YouTube. Listening to what's new. I haven't bought this album yet, but it's high on the greed list. If you fancy sixties/seventies soul, give this album a listen!
  11. Congratulations to Sarah Tandy, Parliamentary Jazz Awards Jazz Instrumentalist of the Year.
  12. Sorry - I’m out of tricks. That error code points to a card fault or a problem with the card read / write hardware or software (which seem to work for you on other cards). So it’s probably the card itself.
  13. Android is the COVID 19 of mobile operating systems. I shall now retire to my studio and come up with a song to the tune of the great Richard Thompson’s. “Vincent Black Lightening” disparaging all things Android.

  17. That's good to know, thanks for sharing! Greetings from Switzerland, David.
  18. Thanks. A bit more than I care to spend though. I only have about a dozen or so LPs, but would like the ability to transfer new ones as I accumulate them. (I used to have milk crates full but they were lost in moving many years ago.) I'm no stranger to 16 bit v. 24 bit audio and don't care to get into a debate in this thread whether it matters. Suffice to say it does to me and depending on the source, I can hear the difference just as I can hear the difference between different violins and cymbals and classical guitars and pianos, etc. I'm on my 3rd LG vXX phone just for this reason. I would be recording on an ASUS Sabertooth 990FX based PC so I'd like to just connect from the headphone jack of the Denon (in Pure Direct mode) to the mic jack of the pc, but the specs on that remain a mystery.
  19. I think I can find some, if you'd really like to go down this path. It is harder to design a product with less distortion, better linearity, lower noise. All of these are part of a measure of transparency of the device. It's possible (though not very likely) that a poorly engineered device can achieve good transparency by accident, but mostly, it's done by design and hard work.
  20. That's why there are more complete measurements being published. Nobody (except for some manufacturers) publish just the THD % -- and in those cases, I fully agree with you -- that's mostly meaningless, even when stated as 1kHz @ 0dBFS. Here's an example of the types of evaluation I find useful, having performed these myself. I look for these when published by others, as they do provide a lot more detail about a device than just a single number. Distortion vs. level with levels of individual harmonics, noise, etc: Distortion vs Frequency: And yes, Chris, these are mostly below threshold of audibility, although the noise floor is higher than I'd like to see.
  21. Pics or it didn't happen. This is interesting. I don't believe it's true that a better measuring product is better engineered, designed, better thought-out, or assembled. Once the level of human hearing is hit, it seems anything further is just men challenging themselves or making products for those who like specs that don't matter. It's like saying one product has a better color red than another. Neither matter to the ears, but matter to the heart. Pursuits of the lowest measurements or the best color red are all fine with me, I just don't like one touted as more important than the other when it comes to sound quality. Better is of course subjective though and we all have our own better.
  22. Actually, I admire @Teresa or anyone who can keep things simple. Nonetheless, I will accept my punishment and maybe even look forward to it!.
  23. We've been around this bush before. My answer is still the same as it was about a week ago in this thread: any devices with distortion measuring below the audibility threshold should be picked by their subjective attributes: color, price, brand, esthetics, weight, engineering, marketing, etc. What arms race and how am I doing anything to contribute to it by stating something as my own, personal opinion/preference? I guess if I had that much sway on the audiophile community, I would consider it to be a possible undue influence, but no, I don't see it. But I would ask you to turn the mirror around. You do have a much greater influence here than anyone else. And yet, you consistently engage in attacks and take actions that amount to censorship against a fairly sizable part of the audiophile community. I would consider that to be much more of engaging in an "arms race". Yes. A better measuring product is a better engineered, better designed, better thought-out, better assembled one. To me, that's attractive. But like I said, it's my own preference and I'm not forcing it on anyone else.
  24. I think that these matters about specsmanship would be a little more honest if there were open explanations when/if some initially extreme value for a measurement might be helpful. Just saying: my circuit has 0.0001% distortion and is so much better than 'Sams' circuit with 0.0002% distortion is a rather useless argument or comparison. Those are blind comparisons with no context. I have this wonderful little paper that some person wrote on op-amps, creating his own specs with LOTS more details than normal manufacturers specs. That 'wonderful' paper helps to show the behavior with much more circuit context involved. It provides much more helpful behavior information for more realistic circuit configurations (of course, not perfect.) There are so many choices of op-amps, that good, understandable objective measurements are so helpful to get started. I can agree that a blind spec without explanation of context is just a little better than irrelevent. This reminds me of the old 'lines of resolution' spec for SVHS and VHS decks. The number was meaningless, but we consumers always know that 'bigger is better', right? Heh -- they way that those 'lines of resolution' were measured was almost meaningless WRT actual quality of video reproduction. They were especially meaningless when comparing consumer vs pro video equipment. (Nowadays, such matters are anachronistic -- we are so spoilt with almost flat & more linear video response in comparison.) This would be similar to the 0.001% vs 0.00001% distortion... For example (another one of my diversions): how many such 'wonderful' preamps characteristics are measured with a source that truly emulates (for example) a MM cartridge? Such transducers are well known to have very wide ranging characteristics and high impedance in certain frequency bands. Such a high transducer impedance can certain cause negative effects WRT modulation of input impedance vs. signal waveform/frequency/level. The noise matter bothers me less, because it is almost impossible for a competent designer to create much more preamp noise than an MM cartridge at frequencies where the ear is sensitive. However, I seldom see a real distortion measurement where the source is at least a model of a cartridge (or, perhaps a low impedance signal feeding through a cartridge of choice, so that an actual distortion measurement can be done.) Big, fat low noise jFETS or medium geometry BJTs can have noticeably changing input capacitance in a normal amplifier circuit. This changing capacitance acts superficially similar to a changing resistance, and in certain cases can produce significant distortion. It WOULD be nice if the measurements actually measured in-circuit/in-situ behavior, and comparisons were made with the priorities openly explained. At least, when someone says that (for example) the 0.25dB down at 20kHz and 1dB down at 30kHz has the effect of significantly changing the sounds of the cymbals crashing -- the judgement can then be prioritized by the person reading the spec. At least, I know how I would prioritize that interpretation of that raw frequency response spec, esp at 30kHz. (BTW, the change in cymbals crashing might be caused more by dynamic input impedance effects, say, on MM preamps.) The general categories of objective & subjective can matter -- the problem with relevence has to do with the priority/usefulness of the actual spec, and the measurement/usability situation for that spec.
