I've heard/seen a number of people state that a single CD player is superior to a CD changer or DVD player. Of course, this is a very general statement. But I'd like to get down to the "nitty gritty" of why this would be the case.
Assuming you're comparing digital players at the same price point AND well received/reviewed, what is it about the single CD player that makes it superior to the CD changer or DVD player?
I'm familiar with the main argument on transport quality. A single CD player leaves a certain amount of "funding room" for a better transport compared to multi-disc players. But... by how much?
Changer: Isn't the design of the motor that spins the disc basically the same? That all you've got on top of this is a rotating platter that puts the disc into place on the spindle? If there's a question of proper alignment (hand placed friction fit versus auto-clamping), wouldn't it be obvious in that the mechanism has to be able to read the tracks--if it's off, it simply won't work right or skip? I know there's also the dampening factor... that the motor mounts should be able to buffer any undue vibration by the motor or from the room. But again, isn't this independent of how the disc got onto the spindle? That a disc changer unit can have good quality motor mounts?
Translation: The digital disc is read by laser and then interpreted into an audio signal--by a DAC (digital audio converter). It can be internal or external. Now, obviously the coded format of a DVD is different from a CD. But programming is programming... anything can be burned into an onboard ROM or EPROM chip. When a DVD is detected, use translation code for DVD; when a CD is detected, use translation code for CD. So... in essence it comes down to the manufacturer using "good code" for the CD. Thus, shouldn't it be inconsequential as to whether the unit supports both DVD and CD or just CD? You could also extend the same principle to MP3's... it's just a different coding format (320kbps supposedly at CD quality). And certainly it seems like the technology exists whereby it can be translated true to form (although I know some people scorn MP3's or FLAC's and stick to full CD). But for now, let's leave the MP3 translation out of the inquiry.
Personal Experience
I have a TOTL single CD/DVD player by Marantz, circa 2005. It's a beautiful unit with smooth, high quality transport. And it sounds great to me. I'm using well respected amplification and speakers, and have tried out a number of good quality CD recordings.
I compared the playback of the Marantz against a Kenwood CD changer and a Sony DVD changer of much lower price points (not the bottom--about middle). On some recordings I could tell differences between the Sony and the Marantz. Subtle, but there... just a little less "presence". I don't know what else to call it. The Kenwood was a different matter. To my ears it sounded almost exactly like the Marantz, except that the bass was a little stronger. Given the Marantz being TOTL, I'd chalk it up to the Kenwood doing a little colorizing. If I wanted a little more bass out of the Marantz for some recordings, I could easily increase the bass control on the amp, by 1 or 2 positions. The quality of the sound still excellent from my experimenting (whereby the Sony turned a little bit muddy at higher volume).
In conclusion, I'd say that the sound quality improvement with the Marantz doesn't justify the cost. Of course, it's a beautifully made unit. Looks great. The drawer action is elegant. But... to my ears, not enough of an improvement to disqualify the others. Now as to personal information, I am approaching 50. My ears have gotten a licking over the years, due to the rigors of life. I've got a very low grade tinnitus going on. My left ear is partially damaged, with some frequencies clipped and the volume just a little less than the right. But I don't notice this unless I'm wearing earphones and turn the right balance down (or listen to a Beatles recording where the left or right channels are periodically insulated from each other). I've been able to tell the difference between great and mediocre speakers, poor and great recordings, crappy and good quality source components.
So... I'm left wondering. Is it simply that my ears aren't truly good enough to perceive the differences between these digital disc players? Or that my equipment isn't "high end" enough to bring out the differences? If the latter, then I guess it really does make sense to always have a balanced system (all about the same quality/grade/cost level). I ran my tests on Canton Ergo Passiv speakers powered by a Sansui AU-719.
Btw, I hope this isn't as controversial as the CD vs. Vinyl argument. I hope this can evoke some very civil discussion to help me find some useful answers that will also benefit others. Thanks.
