What Sonically is the Difference between a $1,500 CD Player and a $10K-$25K One?


I realize opinions may vary, but if I could give an example of two CD players perhaps someone can give me their thoughts on the cost benefits of either one? What would be the difference in your opinion between say a Cambridge Audio Azur 851C CD Player and the Gryphon Scorpio S CD Player? And are the difference truly audible or more technical and rather indiscernible through human hearing?

In general, what makes a CD player (other than build components) 10x more costly than a decently built one other than features?

"My $5 Sony Walkman CD player outperforms any $10,000 CD player. You just have to know what you’re doing, that’s all."
Apparently, you do not know what you are doing with $10 000 CD player, that's all.

If looking at eBay, there is currently no Sony Walkman CD player that would set you back only $5. Shipping ruins it.
I think I’ve had maybe 2 CDs go bad out of thousands covering 30 years. 
"I have LP’s bought 50 years ago that play perfectly."
Have you ever changed the stylus?

"I have many CD’s out of 400 or so that just wont play - not just on fussy hi-fi but in the standard car CD player"
That is what happened to me when CD player's laser started dying.

Are the CDs that did not last original/bought ones or you burned them yourself? Those burned do get messed up after a while. I do not have 50 year old CDs, but some are approaching 30 and last I checked they were fine.
"...what makes a CD player (other than build components) 10x more costly..."
Someone's willingness to pay for it. Parts rarely account for such a tremendous difference.

Having said that, more expensive things have, in my experience, sounded better every time. Whatever that "better" is. It must be something in engineering, but I suspect the crucial part is DAC.
surferandy,
What do you mean when you say that CDs don't last? I have destroyed many for sure by abusing them in cars in the past (no more), but if you take care of them, there is no reason they shouldn't last. I've had many since the beginning that are still going strong.
Choosing my Marantz CD6005 was a two part decision 1. Price /performance and 2. CD’s don’t last.
I am careful with my gear, and despite that I have many CD’s out of 400 or so that just wont play - not just on fussy hi-fi but in the standard car CD player. I have LP’s bought 50 years ago that play perfectly. So, my conclusion is to get a good, cheap CD player and make my vinyl the prime listening device.Gathering thoughts about digital music and have about 120GB saved, just confused as to delivery as it does seem to still be the wild west with massive prices on high end.
Nice spread of DACs. Too bad there's no Denafrips in the mix but you can't have everything. Keep us posted.

All the best,
Nonoise

So much to say here. I’ll avoid the direct comparison because that is very brand dependent and no one has heard most stuff. but the question"what makes one better" is, to me easier to answer. A CD player, end-to-end has many components, and many of those are analog or have analog components - including those before the DAC!

My broadest comment is to migrate from CDs to files, and play them out over USB. For me, using ALAC/FLAC, either ROON or Bitperfect streams sound substantially better than the original CD - played through the same DAC and equipment. In my experience, the best sound and lowest noise  requires running my streaming hardware (and OLD macbook pro) from its battery, not plugged in, sigh. Why better? Likely jitter. A CD transport following the standards probably puts out SPDIF, and a cheap transport - or even a good one - will have some timing degradation.

Note as i have blogged about, SPDIF makes the source (e.g.: that cheap-o CD player) the clock. Your $10k DAC takes jitter form the source.  USB turns this around and simply sends bits to a buffer, where they are re-clocked by the DAC, or can and should be.

Once you have the bits in the DAC portion of the chain one must re-clock very precisely and eliminate noise, both of which contribute to jitter. Jitter, changes the X-crossing point of the reconstructed musical wave and therefore is a plain, old analog distortion. no audiophile magic necessary here. next come all sorts of noise and power supply related opportunities for distortion and of course, the reconstruction filter and analog preamp that is the end of a DAC’s internal functional chain. So if you think capacitors, preamps etc make a difference guess what, you have several of each in there. They must be good.

Bottom line, there are lots of places a transport and DAC can mess up sound. The chip architecture, which most focus on, is probably the least.

Now, just to contradict myself, i have four DACs and have had the chance to borrow several more in my very revealing system. From a Schiit Mido3 (the best $99 DAC i can imagine) to a Theta DSPro/G2 to a ridiculously re-worked MSB (all rework my own designs) these do NOT sound the same - so the comparison of the cheapo to the Theta simply proved that someone can’t hear or has a mediocre system. Ar these differences night and day, awful vs glorious? No! That’s a huge issue in this field/hobby, crazy exaggerations. But the differences are real and manifest themselves even more over long periods of time. My gold test is always "can I go back without missing component X?"

BTW i heard the effect of a $40 amazon sourced Toslink-to-coax SPDIF adapter. You just cannot imagine ho distorted it was. and I have pics of the resulting, ugly wave when i used it in a test jig with test tones (files) and a ’scope. UGLY! Clearly visible jitter to the naked eye! Step function jaggies in the sine wave! Ugly!

Hop this helps

I pretty much stopped reading when I came to, “For the record, I have been in the audio industry from (sic) fifty years as of this September and have a lot of experience and...”

For, the record, I said my Sony Walkman sounded better than a (stock) high end player. 
The blithely made responses from roberjerman and others are an illustration of what is wrong with chat rooms - often no context for the comments, evidence of limited experience by the writers,  unproductive negativity and often no humble opinion. Julian Hirsch, the famous (some would say infamous) reviewer from Stereo Review magazine back in its day was often quoted as saying there was no difference in the sound between properly functioning amplifiers. He never commented on the so-called quote during his tenure as a reviewer but he was interviewed after he retired and corrected the misunderstanding by saying he had said HE could not hear any difference.
It is absurd to claim there is no difference in the sound from a Sony Discman versus a Theta transport and d to a converter just because YOU can not perceive the difference.
For the record, I have been in the audio industry from fifty years as of this September and have a lot of experience and in my experience I have never heard two CD players that sound identical even if similar in price. Remember, a CD player "makes up" all the sound at its outputs as it sees fit through the complex conversion and filtering process fraught with design pitfalls that are expensive to address in the design. (And there is no music on a CD.) Also for the record I have a rule of thumb that in order to make a categorically better sounding component the price will often be nearly double the price because you can't just make a whiff of a change but need to raise the level of all the subsystems in the component. Thus the price of a better sounding component gets higher rather quickly as you go on an expedition to find "the best." Such is life.
Find a dealer with a satisfaction guaranty and compare the units in your own home and in your own system is my conclusion.. Opinions and recommendations will be all over the map.. There are too many variables in systems and environments, not to mention the audio experience is subjective..

Listening in your system and in your home is the only way I know of to find truth for the customer. Forums quickly turn into "makes no difference and you are waisting money" to "makes the world a better place to be, and my unit was a godsend".. Either way you need to hear for yourself..
Magazines, forums and audio shows can help people find interesting gear to evaluate, but other than that, the opinions on most any topic, are so inconsistent to be useless.. You can read 1000s of responses and end up right where you started without a clue, until its in your home and system. Thats just a humble opinion and you know what they say about opinions... In your home, in your system. Trust your ears. The rest is irrelevant.. The BS marketing and, I can hear better than you do, down to the chocolatey sound of a copper wire is all fine, although almost unless when buying audio.. Only way to sort the BS is with your own ears, in a known system and environment like home. Surely people give honest opinions, I'm just saying that a consensus on a subjective subject is not likely to happen.. 

A good signal processing engineer, if they are truthful, will tell you that all decent modern CD players have little difference in measured signal output characteristics. Modern analysis gear can measure things you could never hear. However, things like dynamic range and other characteristics do vary. I doubt very seriously there is any significant audible difference between $1500 and $25000 players. Build quality, looks, etc, sure. I work in defense and we use A/D -D/A converters, quality amps, etc, all the time. Modern devices are cheap and perform extremely well. I suspect the truth is (and I’ll get flame sprayed) you are paying a huge markup and the cost of low production quantity components, rather than greatly elevated sound quality. I don’t profess to have golden ears, but I can hear differences in some gear readily. But when you get to a certain level of quality (meaning not Target level components) there is precious little difference in electronics. I do not include speakers in this since they are both “instruments” and components and can have unique sound qualities.
There's no difference between a $50 and $5,000 one, except for the fancier box.
My 2010 CDP sounds great which at the time cost 1K~1.5K. I have listened to TT and other CDP setups costing 10K, 20K, 30K, 40K, and even more and I am very happy with my CDP setup. The new model of this CDP costs 1K more but I haven’t listened to it as yet. Guess I am happy with my current CDP setup, although the CDT (a cheap Sony unit) could be better. I also have an older 1996 CDP setup (cost about 4.5K) which is also sounds great (perhaps a little better with less features). So I have been enjoying CDP/digital since then and I listen to a variety of music genres. I also have 3 TTs but rarely listen to them. The source and source setup is your choice and it is good to have choices, enjoy.
Well, in these day & age anyone should first consider a SSD-HD as a source. My Weiss MAN-301 plays Music with a focus and a pace that my Esoteric X-05 cannot match. The HD storage is a SSD by Samsung, and FW800 cables connect the HD to the Weiss. Both the balanced analog and the SPDIF digital output of the Esoteric are vastly inferior to the balanced Weiss digital output, as played into a Benchmark DAC3 DX. This is it for my ears and auditory cortex

Then why don’t you sell them and get rich?
Unless you are using the ANALOG outputs of a CD player, where DACs and jitter circuits are involved, the basic CD player is pretty much the same for all players. A motor, laser and some digital electronics. These are about a 100 bucks altogether. Almost all companies who sell $10,000 CD players pretty much buy these components also from the SAME manufacturer. The expense starts showing itself if you use the DAC inside a CD player. Then it can run upwards of 300$ depending on the quality of the DAC design & components.  But if you are using just the digital output, there is virtually no difference.

This doesn't make sense. Just because there are examples of components built from high quality parts that are "inaccurate at best" certainly doesn't mean that all components built using high quality result in inaccurate performance. Indeed, the use of high quality parts often does result in improved performance.

I never made the assertion that ALL components built with high quality parts resulted in inaccurate performance,  as you can see clearly in the quote you excerpted from my post and apparently concede with your use of "some".

I haven’t reached into the 5 digit range with my CD players, but the difference between my $500 Marantz CD6004 and $3000 Marantz KI Pearl (retail prices) was quite noticeable and worth the difference in the price I paid. I bought them both used, and so the difference was only a few hundred dollars.

I sold the CD6004 recently and set it up in my main system to demo and was struck by how much warmer and detailed the KI Pearl was in comparison to the CD6004. So much so that I hoped the buyer wouldn’t ask to hear the Pearl.

I have a lot more invested in my vinyl setup and the KI Pearl sounds better to my ears with some of the better mastered CD’s I have. The clarity and insight into the music as well as the warmth it conveys make for a very enjoyable listening experience.

I’m sure there are diminishing returns when you get up over $10K, but I have no reason to think that there wouldn’t be a difference in sound quality in comparison to the Pearl, hopefully for the better.
ahofer

The "large and audible" part does not logically follow, and assumes far too much integrity on the part of the industry. There is plenty of stuff built from high quality parts that is inaccurate at best, and still more where the high quality parts do nothing *audibly different*
This doesn't make sense.

Indeed, the use of high quality parts often does result in improved performance.

But I always suggest that users listen and decide for themselves.
I can give you feedback on my direct experience with this question. The price range isn't as big as you would like but I've spent a number of hours trying to answer the question you raise.

Currently I own two CD players, one transport, and two DACs. These are a 1998 vintage Krell CD 250/2 (HDCD compatible $3200), Marantz SA 8005 SACD player ($1200), 1996 vintage Resolution Audio Quantum DAC (HDCD, $3500), PS Audio Perfectwave transport ($4000), and PSA Perfectwave DAC ($4000). I recently sold an Emotive ERC-3 Gen 2 ($450) that I also compared with these other players.

Here are my brief observations using my system of a Krell KRC 2 preamp, Krell KSA 300S amp, and Mirage M3si speakers with a Velodyne subwoofer. Since my preamp has a lot of inputs I've got all this gear hooked up all the time. All comments below are using standard Redbook CDs unless otherwise specified.

The PS Audio combination and the Marantz sound remarkably similar on regular CDs. I've compared them over a dozen times and I can hear a modest difference on some CDs and no difference on others. The PS Audio has a sharper transient attack on music that is recorded well but otherwise they both sound really smooth and musical.

The Emotiva and the Marantz sounded very similar also. On regular CDs it was hard to tell the difference. I think I could hear a smoother decay of instruments on sparsely recorded music on the Marantz but on regular old butt rock I couldn't hear a difference. The Emotiva decoded HDCDs but I sold it when I bought the Krell player since it does HDCDs also. I have over a hundred HDCDs so I need a compatible player.

I kept the Resolution Audio (RA) DAC because it does HDCD and I've got it hooked up to the Marantz as a transport. This is kind of nice since I can directly compare the DAC in the Marantz with the RA DAC on the fly. The RA DAC has a different character that is hard to describe. I hate terms like "sweeter" but it has a noticeable sound difference than the Marantz DAC. One is not clearly better than the other, they just sound different. If I had to describe it I would say that the RA sounds more like my turntable - it has a richer lower midrange. I could live with either one.

The outlier here is the Krell player. It does sound different than the other players. It's a little brighter in the treble (some might say "harsh") which stands out on some CDs. On some CDs I prefer the Krell but on others, particularly on albums that were recorded with hot treble, I prefer the PS Audio or Marantz.

I have several SACDs and CDs of the same music and I've compared them using both in the Marantz and using the Marantz as a SACD player vs. the PSA combo as a CD player. Results range from virtually identical to strikingly different. I've concluded that the recording and mastering differences on SACDs completely swamp the difference in players. IMO SACDs are a crapshoot. Some are way better than the original CD and some sound pretty much the same. The dual layer SACDs where the same mastering is used in both formats sound pretty similar using the Marantz and the PSA.

I have a 90's vintage Denon turntable with a Hana cartridge. I've got a bunch of music on vinyl and CD and I've compared a number of them. The music where the transfer to CD was done with care and compassion sounds good on both. All of my digital sources sound a lot like my turntable but the Resolution Audio seems to have the most similar character. However, there are CDs where the transfer was terrible. The digital version sounds much worse (compressed, dull, lifeless) as compared to the record. If one were to single out these perpetrators they could easily conclude that digital is inferior. IME it depends on the recording.

For me the lessons here are:
1. In no case does one player "blow away" another player. There are differences but I could happily live with the Marantz or PS Audio forever.
2. I would not recommend the Krell or another vintage player as one's only CD player. I think that digital playback has indeed progressed since the 90's.
3. I'm sort of sorry I sold the ERC-3 because that was clearly the value leader. I would really like to compare the Emotiva directly with a megabuck player to discern the difference. Maybe in a million dollar system there's a huge difference but I suspect that in most real world setups the difference would be subtle.

One more point. There is a huge treasure of wonderful music that was well recorded and lightly compressed from the late 70's through the early 90's including rock, jazz, and country. The best sounding CDs in my collection are mostly from this period. I am constantly discovering artists from this era that I hadn't heard. To say that all digital music is over compressed just isn't true. If you are limiting yourself to the late 90's forward you are missing the best recordings.


When you add up the differences in drive quality, analog output stage quality, digital output stage design you can start to understand that there are very large and audible differences between CD players, amplifiers, dacs, loudspeakers etc.

The "large and audible" part does not logically follow, and assumes far too much integrity on the part of the industry.  There is plenty of stuff built from high quality parts that is inaccurate at best, and still more where the high quality parts do nothing *audibly different* (need I point out this has been replicated hundreds of times with a wide variety of equipment?).  Sometimes the allegedly high quality build doesn't even *last* longer.  Otherwise we could just budget more money, buy without listening or specifications, and have a better system.  Many manufacturers are selling you status, bling, and manufactured flattery, not audible or important differences, IMO.

I believe if it were possible to scatter plot price vs sound quality, you would get a blob of points through which you might be able to fit an upwards-sloping curve (with decreasing slope and a low R^2), and you would get a handful of high-priced points  as low in sound quality as many of the very low-priced points.

Once in a while a great piece of gear "falls from grace" and loses its appeal. Sometimes for poor reasons. In the case of PS Audios PerfectWave Dac, when the newer Directstream Dac came out, reviewers sited the new unit as superior to the old. Thus a Perfectwave Dac can be bought for in the low teens. I bought one and I think I paid $1200.00 or so. Coupled with even a CD transport or player, I was blown away by the sound. To me it sounds like a $15,000 rig that I paid $2000.00 for. I can't believe that PS Audio will gut a Perfectwave to update to a directstream model. I also bought a directstream DAC so I can A/B the two of them. (I haven't gotten around to it yet). My two cents.
You don’t have to be too swift 🏃‍♂️to chase electrons since they barely move at all. 🐌

On the Kalahari you don’t have to be the swiftest wildebeest, you just have to be swifter than the slowest wildebeest. 🐆

I love all the folks that assure you that there can be no difference of any import. Try some auditioning at an audio salon, and I'm pretty sure you will then know the answer.
Agreed. It amazes me how in a hobby based on listening, some will ask others to tell them what they should expect to hear. There's no substitute for listening and deciding for yourself.
... you can get some very real, sonically significant and musical improvements as you go up the food chain. But the folks pointing out the diminishing returns with greatly increasing price certainly on to something ...
Oh yes, there are diminishing returns, no doubt. That's why every audiophile must decide the value proposition for themselves.
All the money saved by not chasing perfect electrons will also give you the opportunity of having two systems, one Solid State, the other Tube.

A mix of Digital and Analog source equipment.  Here again, the differences are easily audible, and comes down to a preference, perhaps even Solid State for this content, Tube for that.

It is advisable to avoid the esoteric when trying your first tube system, any decent tube system will be involving enough to reveal the difference from SS. 

Now LP. Any decent TT/cartridge properly set up (learning first) combined with any decent RIAA phono preamp, SS or Tube, will reveal the difference of LP to CD.

LP content, like CD content, varies greatly by the recording/production skills as much as the artists skills.

LP into SS or Tube, differences will also be easily heard.

I advise learning about Analog rather than chasing tweaks.

After that, it's on to tweaks, god help you to stay sane.


The cheapest CD player, given a great recording, can produce an immersive listening experience in nearly any decent sound system. 

The place to invest your time and then invest your money is speakers. Time to learn, time to listen in showrooms, audio shows, time to understand your listening space. Critically, time to understand it is best to avoid going for 'too much' (usually too much bass). Time to learn that if speakers are well chosen for your space, you won't need to plaster sound absorbing panels hither and thither.

Without a doubt, money makes a huge difference with speakers. Far beyond any source component or cable or tweak.

After the right speaker choice for your space, what will undeniably sound better in your system is all the new source material you can acquire because you didn't spend money on imperceptible, or barely perceptible differences. The joy of discovering new artists, new genres, is far far better than chasing perfect electrons. 




I ain't no expert, but it seems that the difference is between $8,500 and $23,500 when I do the cipherin'.

Cheers!

Doesn’t anyone else get really tired of all the whining about SOMEBODY ELSE’S STUFF?If you want to say "My attempts at xxx have uniformly sucked". Fine. Please do not then decide for everyone else theirs has to suck too. And even worse, that they must be deluded since they can't hear it sucking.

geoffkait,

I actually enjoy reading posts like yours. It is true of course that digital was pretty terrible for the first number of years, but now that I have been living with a competent transport and non-oversampling DAC for years, I enjoy the great sound (perfect...? NO) and grin at all of the outdated criticisms of digital's deficiencies.


>>>Many audiophiles think their system sounds fabulous. As long as you’re happy I’m happy 😃 
Whichever way you look at it, the "loudness wars" are a huge reason to think carefully before investing in another CD player. Listen to a recording like West Side Story (original Broadway cast, Larry Kert, Carol Lawrence Chita Rivera etc) and much of your collection might start sounding a little flat with far from life-like dynamics.

No CD player, or even system, can help you with that. Unless you're into Jazz and Classical of course, or anything but mainstream Pop/Rock.

Why the **** should anybody should seek to compress Motorhead??

@fstein Expensive CD player = "The sound of money burning". Indeed.

On the bright side, its all great news for the vinyl revival and horn loudspeakers. And for modestly priced CD players.
The problem with 1500$ CD players is simple - they are not good enough. So people feel ripped off as a difference between 200$ and 1500$ CD player is sometimes very small. Magic happens at 3000-5000$ price tag. So, my recommendation would be, if you can’t spend 5000$ on your CD player, then buy any CD player. They are all pretty much same. But if your budget allows you to spend as much as 5000$ new (or 3500$ on second hand market) then go for EAR Yoshino Acute, Lampizator Big 7, Audio Note CD players. Those 3 brands will give you the best value for your bucks. You'll have all advantages of digital and very analog type of sound. If I could go back in time, I would buy only top gear right away (Atma Sphere amplification, Lampizator DAC and Devore, Audio Note or Quad speakers). I've spent a lot of years upgrading from one component to another (and loosing money each time). In this hobby the one shall simply take a mortgage of 20.000$ and buy the best gear he can get for that money right away. It's not different to buying a good car. For 1500$ you can get only a crap. But for 20.000$ you will have a decent and safe car you'll keep for many years.
I love all the folks that assure you that there can be no difference of any import.  Try some auditioning at an audio salon, and I'm pretty sure you will then know the answer.  IME you can get some very real, sonically significant and musical improvements as you go up the food chain.  But the folks pointing out the diminishing returns with greatly increasing price certainly on to something, as well as the crazy-quick and steep depreciation of anything digital.

Get out and explore with your ears.  That will tell you a lot.
The way they sound. One of the things to consider is the system and the room. It is likely that a person owning a $1500 item may not have the rest of the pieces and a room that will let the differences be heard. Now go the other way. A person who has a setup that includes a 10k-25k player would likely hear the difference if a swap out to the lower cost one was made.
There is not.  300 bucks is tops and you will get fantastic sound.  The only important things on a CD player are:

1) speed stability (the motor), very easy to achieve with todays electronics.
2) If u are using analog outputs, the DtoA converters (may be a bit expensive for top of the line Wolfsons)
3) Quality of jitter circuits.

These are all achievable in a FANTASTIC way for under $300.

Night and day difference in sound quality , if you buy from companies that have established and  doing digital for a while 
it is like the difference of a $1k turntable cartridge,and a $5k  cartridge, realism on a much higher level. That being said as digital 
technologies keep getting better the price of sound quality has 
dramatically come down ,and there are some very good dacs out there $3k or under.
I currently have Paradigm Prestige 85F towers.  They came with metal jumper plates.  Will I hear a significant difference if I replace them with speaker links?  I have Tara Labs Apollo speaker wire and wonder how important it would be to spend $265 for the Apollo speaker links as compared to the $125 Equinox speaker links?
Kind of like the "Emperors New Cloths".  If you spend $10,000 you will talk yourself into hearing the difference.  Buy a new car or pay down your mortgage instead.  It is like anything else with audio.  It minimal returns for money spent in my opinion.  However, the wealthy folks in the group don't have to be practical.  I think it is being able to invite your friends over to tell them now look what I have.  Kind of like $9,000 speaker wire.  Wonder if you priced Nordost at $240 and Tara Labs Appolo speaker wire at $9,000 if people would convince themselves the Tara Labs to be superior.

I have an OPPO player and wonder if there is anything I could do inexpensively to reduce vibration.  Seems like reducing vibration on both CD players, pre-amps and amps make a difference.
There are places where large sums are wisely spent, and others where it is a fools errand.

Part of this hobby is discerning one from the other.  Not all of us have unlimited funds, yet we aspire to great sound to give us continuing joy.

CDs have the issue of player as well as recording.  And lasers have their own category.  Then you get into streaming where the source material may be suspect.

It gets more difficult to balance these factors juxtaposed against  our own individual preferences as we each continue our sonic journey.

For myself, a CD/SACD player over $2,500 is money not well spent.  Marginal cost versus marginal gain.
