As far as I remember the only difference between the 2 is the777 featured balanced outputs as well as unballanced and the 555 had fixed and variable unbalanced. Weighs in around 14KG.

    Up until early 90's ES meant something, they were better built, more refined electronics, better power supply, more metal less plastic... It was Sony higher line of HIFI equipment with great attention to both audio quality and materials. But then Sony started slapping ES on everything: the same unit sold in one country as a regular hi-fi component is sold in other countries as "ES". MultiCD changers were never meant for audio enthusiast i really do not see the point of an "ES" CD Changer. I am not surprised at all it is basically a regular CD changer with more buttons on the front and a double plater in the top cover.

      TBH, that just sounds like cargo-cult snobbery that has circulated the industry since such things were invented. I think we've all internalized that, and maybe it became a self-fulfilling prophecy where they never sold to audiophiles because audiophiles would never buy them, and thus why go to the nth degree to make them audiophile worthy.
      But, technically, there's no reason a CD changer can't be 100% as good as a single-CD player. Think about it. What's the actual difference? One has a tray with a slot for one disc. The other has a tray with slots for 5 discs. The transport itself still has to clamp around the disc, and once it does, it's no longer in the tray -- so the part that differs is completely out of the picture.
      The transport quality, the features implemented in a microcontroller, the DAC, the PSU and filtering ... that can all be absolutely identical between a flagship 1-disc player and the changer. (With, of course, the exception of a little extra code, another motor, and a few parts to physically manage the turning carousel.)
      I'm not sure what it is about audiophiles that insist on minimalism, like some rite of denying yourself convenience is necessary to enjoy the experience more. Even ridiculous stuff like "turning off the digital output for... you know... signal purity" -- it's just ridiculous. CDs are digital. They have to be decoded. There's GOING TO BE a microprocessor running at all times, because there can't _not_ be. Is a lit display on the front going to be the thing that wrecks the analog output, or is it going to be the CPU and motor driver?
      To me, the whole "ES" thing was always about making small choices in the engineering. I build stuff -- just for fun -- and sometimes I have to choose between the 40 cent part and the 197 cent part. They both do the same thing. The extravagant one might do it 1% better. If my goal is perfection, I go for that extra 1% and let it accumulate with all the other 1% improvements. OTOH, if I'm going to use it as background music in a restaurant, the cheaper part is already overkill. There may be no other change than which capacitor I chose in a critical part of the circuit. It always struck me that THAT was the real difference between ES and non-ES devices. You paid a little more to get slightly more expensive parts when the engineer had to pick between frugality and performance. The rest of the box might be exactly the same -- because if you weren't making any compromises on the basis of cost anyway, then why reinvent the wheel? Maybe you get a fancier front panel, a metal knob, and gold-plated RCA jacks just so it _feels_ a little more premium, but otherwise, why change things that are already not the bottleneck?

      @@nickwallette6201 Audiophiles actually were the first to adopt CD players. After all when they first hit the shelved they were bloody expensive.
      A changer or jukebox can and does sound as good as a single disk. As you pointed out once the disk is clamped in it is read by a laser and as long as the processing electronics are the same there is no reason that a multidisc changer won't sound identical to a single. The only real reason for a simgle is for that "I want to select my CD from my wall of discs and load it and play it start to end mentality of vinyl users. It doesn't matter that only bands 1 and 5 are good and 2,3 and 4 suck, a true audiosnoob will listen to the garbage tracks because they are "listening to an album". 5 disk units are nice because you can load 5 discs up and put in whatever 5 you want to hear.
      The mega are really nice because you can load 50 to 400 depending on what unit you have. I have 3 200 disk changers. 2 in use 1 spare. What is nice is one can control the second. So I can load 400 discs throw it in random / mix mode and while one is playing the next disk is loaded in the second changer and as the first is ending the second starts and there is a 2 second fade on the first. While the second plays player 1 finds and cues up the next track and when the second one finishes it cross fades back. It is so cool to watch the 2 players in automatic playback mode. Looking at a computer screen ruining a music automation like Zara is pretty boring. (zara is a radio station automation program, which I run for stuff on the PC as it's great but nothing like watching 2 CD changers just do their job and the discs in the carousel spinning back and forth as it loads the next disc. I ripped all my CDs and burned compliation discs on CDR to load into my players, so I only hear the tracks I like. None of the filler garbage.
      I do consider myself an audiophile BTW. I have multiple systems, both tube and SS and vintage equipment like a macintosh 1600, sansui 9090 as well as several other amplifiers and receivers that I swap out to listen to.Unlike the audiophools (there is a difference BTW, the latter overspends to get equipment) a real audiophile doesn't spend ludicrous money on the toys. He is patient, and waits for specific equipment to come up in estate sales ect, andgets his stuff for next to nothing or for free. Free is good and that is how I got a fair bit on mine including my technics SA700, sansui 9090, mcintosh 1600 and many other pieces and speakers.

    • @Watcher3223
      @Watcher3223 Před 23 dny +1

      Well, it depended on the model, whether it was Pioneer Elite, Sony ES, Onkyo Integra, etc.
      For lower end models of the line, there wasn't much to differentiate a Sony ES unit from a regular Sony model.
      Of course, you started to get more unique features in a Sony ES unit the higher you went up for the model ... with a concurrent increase in the retail price.
      A Sony CDP-X111ES was the lowest end CD player of the line for the era it was made. Rudimentary resonance dampening of the top metal cover by affixing an additional metal sheet to the inside of it as well as a front aluminum faceplace.
      Next up would be the CDP-X222ES, which was almost equivalent to the CDP-X333ES in terms of sound but still using a standard disc drive like its lower end sibling.
      Then you had yourself the CDP-X333ES, a midrange model with certain unique features over the lower end offerings, such as a linear motor for the optical pickup instead of a gear train for faster and smoother random access operation, and dual power supplies, one for the digital side and the other for the analog side.
      Then you had the CDP-X555ES, next up with all the features of the X333ES but now with a copper chassis with frame and beam construction and compartmentalized assembly, and some circuit boards are made of a glass epoxy substrate while other boards still used a phenolic substrate.
      Then there is the CDP-X777ES, which had a seriously built disc drive (which is not so easy to find parts for, unfortunately), even beefier dual power supplies, all circuit boards use a glass epoxy substrate, very high end D/A converters and more elaborate analog output circuits featuring balanced (XLR) outputs in addition to standard unbalanced outputs along with both optical and coaxial S/PDIF outputs, and so on and so forth.
      As for the CD player I have, I use a Sony CDP-X229ES (basically the same as the CDP-X222ES). It works well and sounds nice, though I've connected my CD player to my STR-DA4ES receiver via S/PDIF to handle the D/A duties. The X229ES uses a more commonly available optical pickup compared to the X333ES, which was one reason why I went with it.

    I actually think the manufacturers were initially not averse to including features that facilitated recording. Because to them, it was just common sense that you buy a tape recorder to record things and most people are just naturally going to want to make mix tapes and so forth. As I understand it, things didn't get too heated until digital recording started to become available.
    To this day, they still put that stuff that goes sticky on things. Every time I buy a new mouse I have to make sure it doesn't have that stuff on it.

    My C555ES is very nice, and plays SACD, also has surround outputs and digital outputs coaxial and optical as well, so I think that is a better 5 changer than others. in the inside of it, it is also different with a ton of fat golden caps, the tray is sandwiched between the caps and the bottom of the unit, which makes it a bit more problematic to work on. But it works perfect. Got it free cuz it wasn't opening, which of course it was only a belt that was stretched out. Luckily it has a special bottom opening to change the belt. Nice unit in my opinion. Sadly missing the remote. (Also plays CDRW and all the other ones)

      FWIW, the Sony D-5 (or D-50, depending on where you are when you ask) was Sony's first portable ... _technically_ battery operated... or operable... player. It plays CD-R just fine.
      The biggest problem with CD-R is how well it reflects IR -- particularly, the difference between the reflective and diffractive bits. It doesn't have the optical "dynamic range" of a pressed CD. In the early days, laser optics were usually calibrated for the right amount of intensity (on the laser) and gain (on the pickup). Later, that stuff was handled more and more by servo circuits.
      So, on an earlier player, if it were calibrated for pressed discs (which it would be, because CD-R wasn't a thing yet), then it would work only if there was enough margin in the RF amp's gain and bandwidth, and the detector's ability to distinguish noise from signal. Some players had it, some didn't. It was a crapshoot.
      Later players could just improvise .. e.g., by increasing the pickup gain when confronted with a weaker signal. There are still limits, because at some point you're just amplifying noise and trying to interpret it as a valid signal. But it's at least able to shift a little.
      That was the whole "CD-R compatible" thing. It was just the vendor saying, "yes this transport is able to cope with the different optical requirements of CD-R discs." It didn't really take much, if anything, to add "support" for it. Just a little extra attention to detail, maybe a tweak or two in the front-end analog circuits or the code handling it, and some practical testing. Then you can hand it over to marketing to do their thing.
      AFAIK, CD-RW is the same, just with even less ideal reflectivity, but I'm not actually positive about that. There may be some on-disc differences to accommodate the ability to append and change data, whereas on a pressed disc or CD-R, once you've recorded the TOC, that's it. All you can do is write a new session (which most players don't recognize either.) That's all inside baseball that, unfortunately, I've never been privy to, but would love to know more. I HAVE been able to coax the CD player in a prior car to play a CD-RW disc, when it wasn't designed to do it. It took a few tries, and wasn't very resilient, but it did manage once. That tells me, whatever's on the disc could be interpreted by a player that wasn't made to read them.

    • @nickwallette6201
      @nickwallette6201 Před 22 dny

      It's damping. Panels of aluminum or thin steel vibrate, particularly at their resonant frequency. The heavier it is, the lower the resonant frequency. If you can get it low enough (by making it stiffer and/or heavier), then it becomes irrelevant.
      Now, does the resonance of a sheet of metal covering the top of a player matter to anything or anyone? Probably not a whole heck of a lot. The player is already tracking a disc that is spinning at a few hundred RPM, and wobbling in the X, Y, and Z axis, one mm above the optics. Is the sheet metal, vibrating at 150Hz, going to be the straw that breaks the camel's back? Nah.
      But, if you paid double for a box that was engineered to have a 3dB quieter noise floor, you would probably be turned off by a floppy top panel. So, fine, glue another piece of metal to it. Now it brings the goods and feels more expensive too. Psychology matters.

Yes I know the PCM is 16 bits, but it was split into 2 8 bit words for conversion to 14 bit PWM. This is because the laser could not write 10101010 The minium it would write is 3 ones and 3 0. So the 8 bit code was turned into something that had at a minimum 000 or 111 in sequences. so for example you could write 11100011110000 and any combination that. 11110001111000, 11111000000111 ect. The result was a PWM type waveform that when reversed went back to the original PCM signal. It however did lead to newer converters that could work at the single bit level (MASH - ,ulti stage noise shaping) where the PWM encoded waveform was converted directly back without going back to PCM and then D-A

      @@12voltvids It's definitely 75 frames. If you've ever used authoring software, either burning programs with really good audio support, or something Adobe Audition, SoundForge, etc... there's a timescale specifically for audio CD that does M:S:F. I've been using software like that since I was a kid ... Cool Edit on Windows 3.1 > CE Pro on Windows 95 > Audition on XP and Win 7, and now Studio One. Also been knee-deep in CUE files to make or archive CD audio discs since the late 90s -- remember Golden Hawk Technology's CDRWin? I cannot even count how many mix CDs or band demos I crafted by hand, wrote CUE sheets for in Notepad, and then burned at 1x to keep the buffer from underflowing on old 9x systems with antique recorders. Trivia like that is etched into my brain forever now. haha
      While we're nerding out, EFM is more about clock recovery. You can't have long strings of consecutive ones or zeroes, because there's no clock signal in a bitstream read from disc, nor SPDIF (e.g.), or many other serial protocols that only have a single data line. So, you derive the clock from synchronizing on the transitions between bit states. If you have too many of the same state, ergo no transitions, then your source and derived clocks start to slip, and you don't know when exactly you should be sampling the input anymore. Then you end up missing bits, or reading the same bit twice, or reading on the edge of bits, etc. Since there's no reason you couldn't have a long string of digital silence (PCM sample bytes of 00000000), particularly on lead-ins and lead-outs, then you need to be able to encode words like that indefinitely without losing clock sync. EFM ensures this by adding bits to every word, such that no valid code word contains too many consecutive ones or zeroes. Any 14-bit combination with more than a couple in a row is dropped from the code table. With the extra 6 bits, the remaining codes are all "random" enough to keep the clock recovery fed.
      There are dynamic bit-stuffing alternatives that just lengthen codes that need more transitions, without affecting the length of codes with sufficient transitions, but then you end up with variable-length words, and therefore your storage capacity depends on the data instead of always being a predictable fixed length. I guess, with CD, they figured there was more than ample capacity to "waste" some on superfluous extensions, and in return, they got a more straightforward decoding algorithm (easier for early digital hardware to accomplish) and a guaranteed known capacity.

      But aside from going through them when the unit was new, I never once ever seriously used an environment effect on a receiver. Why would you want that? "Oh, now it sounds like I'm listening in a large box. Awesome!" Receivers now have tons of features to _remove_ excessive room acoustics. Why was it ever desirable to _simulate_ them?

    manipulating the sound to what I think sounds good to me. I hate the idea listening to music sounding flat straight off the cd, vinyl or my reel to reel. That sucks. Flat sound has no life to it...its lifeless. I have a 24 channel mixing board connected to my stereo system in the audio signal path. I even have a 32 channel EQ connected. I can make an A and B comparison to see what sounds better. In my opinion the audio that has been treated with my mixing console and EQ sounds so much better it's like night and day. The audio that's been manipulated has much more texture and more depth and stereo imaging than the flat sounding version. No way! Your ears and mine Dave didn't come from the same mold, we hear differently.

Most of the time I don't agree with the artist or even the recording engineer who did the final mix I don't agree so this is where I come in with my gear to correct the audio to please my hearing only. To what I think it should sound like not the artist or their engineer. All I ask from the engineers from the 24 track mix down to the 2 track Stereo tape to the master engineer who cuts the record to keep the audio as flat as possible so I can make my own adjustments at my end when I get the final product in my hands whether it's from vinyl or cds.
