I agree with you on these sites, it sorts the BS from the real thing and measurements don’t lie, there not subjective either, it tells you what you’re paying for. If you read his report, the company refused to sell the ISO Regen to him when he ordered it. How he ordered it he didn’t say..... I wonder what motivate them with that decision. That one he measured was from a member and send it to him to be measured. 1 Link to comment Share on other sites More sharing options...

Yes, but you must interpret them properly. Please see the following by Rob Watts: The blind test IMHO is the ultimate arbiter and they are easy to do for just one person. Unless of course you have learned to trust your ears - I personally do not do them, but if you are just starting out its a very good idea. Walk out instantly from an store that will not do it for you, What is probably going on and why I found the ISO Regen made a bit of difference, but the linear supply into it an even bigger one is noise floor modulation talked about by Rob (amongst other things) and the Explorer 2 uses the power from the USB. Just a guess - but with that DAC is was particularly noticeable. It's a really interesting video - noise-floor of 130db vs 150db you would think isn't really audible - but it actually is - quite surprising.

Thanks Bill Theres one thing you should know about me is that i don't buy into sales pitch especially from a sales engineer like this guy. From the same site the Chord shows up impressive measurements but its no better than $500 Chinese made product: a Topping DX7.... It may sound better and sweeter to the ears but we are talking about Chord at $2700 to $500US! Look at the resolution thats measured for both! https://audiosciencereview.com/forum/index.php?threads/review-and-measurements-of-chord-hugo-2-dac-and-headphone-amplifier.2349/ https://audiosciencereview.com/forum/index.php?threads/review-and-measurements-of-audio-gd-nfb-27-38-dac-and-headphone-amplifier.2486/ Edited July 15, 2018 by Addicted to music 1 Link to comment Share on other sites More sharing options...

If 150dB, or 130dB below the peak signal level WAS audible.... it would blow all conventional understanding of physics out of the water. ..... but, it's not implausible that what is being referred to in the video IS audible.... but the explanation is that what they've measured is not actually what they're hearing .... but, rather the 'symptom' of some other thing they are hearing.

Anthony1 Posted July 16, 2018 Share Posted July 16, 2018 Yes expensive players/transports do sound much better than basic ones. Far more insightful and detailed, better quality mechanisms and electronic circuitry etc. If buying 2nd hand, determine original sale price as an indicator of quality pecking order, as a unit that was say $7k and then bought for 2k or less will sound excellent. Example, a McIntosh sacd player is a noticeable step up from a Marantz sacd. That said a modern Marantz player is vvg indeed, but a bit conservative in bass oomph. Last comment being there is so much information that CDs contain, it takes a few tweaks and a half decent player to obtain it. PSAUDIO Directstream is worthy of consideration if buying new rather than 2nd hand. Link to comment Share on other sites More sharing options...

This is off topic but just so people understated why I mentioned it, its about self reference. We have a rule here about debate on blind tests is confined to the Great Debate Section. But even mentioning that is discussing blind testing. Its a strange quirk about English (and any other human language of course) that we as human beings sort that sort of thing out. Here the key word is debate - we were not really debating it, I was just mentioning if you are worried do a blind test. But if you wanted to debate it then you cant really do it in this thread. It takes you into strange realms like Godel's theorem and the halting problem - the fact you cant write a computer program to determine if another program will ever stop.

Of course i know in audio that the law of dimishing returns applies, so i am expecting snall changes for big bucks.... Hello, and thank you for posing this question. I think that your comment, above, is on-the-money. On 13/07/2018 at 7:26 PM, Alpine Electrocats said: Thanks everyone, lots of really good answers here- most obvious to me is that a really good dac is the thing to get-it would cover all bases- for those of us streaming to thise of us with big files on our computers and those of us who play cds. Again, I think that your logic is sound. Using a single DAC will provide more consistent sound from the various sources, especially in terms of volume level. I have read the replies to this thread so far, and, frankly, I don't know what to say. You have been given the impression that there are limitless, audible improvements available, if only your wallet is deep enough. I will say that I strongly disagree and leave it at that. I do think that a quality, well-engineered and well-built DAC is a good investment. It should give a flat and accurate output with a good current drive. The components should be chosen, and build should be quality, so that there is very little variation between units, if they were to be measured, and there is very good likelihood that the sound, and measurements, will stay at the same level for many years. I have not been DAC shopping for ages, but if you cannot get a DAC, that meets the above requirements, for $1000-ish, I would be quite surprised. Perhaps some extra cost to allow for your need for a number inputs on the DAC, to accept your sources. Is there such a thing as a digital input selector unit? I doubt it: it may cause issues with DRM, digital rights management. Beyond ensuring good general engineering quality, I cannot see a scenario where you have another $X to budget on hifi and it would not give you bigger improvements to spend it elsewhere in the system. There is an old truism that says garbage in, garbage out. But it is only true when you have garbage in. With modern digital audio, well-built and functioning, there is no garbage in, other than bad recordings, or bad connections and cabling. I fear that I may have invited debate, which I want to avoid, with that comment, but in committing myself to give my best understanding in replying to your thread, I could not leave it out with good conscience. There are still areas to seek and eradicate garbage entering your system, and this is not the best place to look for it. In no particular order, and excluding recordings, the main areas are: LP player behaviour, speaker behaviour, room behaviour, speaker placement and listening position, connections, potentiometers, failing electronics, voltage level matching, and channel matching. That is a lot of areas to attend to. Please feel free to ask any follow-up questions, and I will do my best to answer helpfully.

audiofeline Posted July 27, 2018 Share Posted July 27, 2018 The OP's original question "Do expensive cd players sound much better than basic ones?" reminds me of when CDs were coming on the horizon, and the Philips guys in white coats were out there talking to journalists about how CDs could produce "perfect sound" and how this little shiny disk was indestructible (the demo involved getting a knife and cutting from the inside to outside edge, and then the CD would then play back perfectly. We would shudder comparing the effect of this demo on a vinyl album. Strange how they never cut the CD in a concentric circle, isnt' it). Anyway, back on topic, these boffins also said that because the sound of CDs were digital 1's and 0's, it meant that different hardware wouldn't make any difference in sound quality - whatever player you had would produce "the perfect digital sound". Whilst I liked the concept that there might be no "audiophile" differences and that I might be able to get the "best" quality player for the cheaper price, I can recall thinking that Shirley this couldn't be correct - the quality and design of the electronics must contribute a difference. After the first generation of consumer players were around for a while, people were starting to notice a difference in quality between the players. Then people started talking about how they could improve the sound of their players with various tweaks, like resting the CD player on a towel. When I heard these comments, I smiled to myself with a personal smugness that my instincts had been correct - different players do have different quality. Something I've noticed every time I've upgrade CD players. Link to comment Share on other sites More sharing options...

betty boop Posted July 28, 2018 Share Posted July 28, 2018 Just good engineering sets apart. Have peep under hood of either. a CD player is a transport, dac, and typically that’s made up of drive, dac, analog stage and power supply. The implementation of these from basic to more elaborate what sets these apart. things like, soundstage, details, refinement and dynamics usually what impacted in my experience. 1 Link to comment Share on other sites More sharing options...
Assisi Posted July 28, 2018 Share Posted July 28, 2018 @Alpine Electrocats The answer to your initial question about improvement for the reasons that others have said is a definite yes. The extent of the improvement depends upon many things which I cannot answer. The underlying question is whether an expensive CD Player will of itself improve the SQ outcome of the system that it is in. The outcome will be dependent on all the elements of the entire system. A weak link in the chain can negate the impact of rest of the components in the system. There is no point including an expensive CD player in a system where the rest on the components are low quality unless it is part of an overall long term upgrade strategy. The matter of upgrading is a whole question on its own. John Link to comment Share on other sites More sharing options...

I will say that I strongly disagree and leave it at that. @Grant Slack My perspective is opposite to yours and I am in agreement with others. To me price, cost or expense are important indicators in the context of a quality audio outcome. A system comprising expensive components if properly implemented will definitely outperform a low cost one. In my experience I have found that there is a definite correlation between what I have spent and the outcome when I have chosen well with rest of the system in mind. As I have spent more, the quality of the outcome has definitely improved. In relative terms the outcome may not be directly proportionate to what I have spent in the pursuit of quality because of the law of diminishing returns. Nevertheless, the results for each step I have taken have been extremely satisfying for me. There is always something better out there if you have the wherewithal, inclination and in some instances permission to spend more. It is all about relative affordability. What is affordable to one may be too expensive to another. This applies to CD players and all other equipment. Choosing well and getting the overall synergy of your system right is the key outcome. To some extent, to paraphrase a saying, “to find the quality follow the price”. John 2 Link to comment Share on other sites More sharing options...
