Our take on the Sony CDP-CX455

With the CDP-CX455 mega changer from Sony, you can load up your 400 favorite CDs, and keep them ready for instant playback. Spin the twin front jog dials to maneuver your way to the desired disc and track, or use the included remote control. And you can take advantage of the random play mode for a surprise mix of your entire collection. For maximum playback flexibility, the CDP-CX455 handles CDs, audio CD-Rs and CD-RWs, and MP3 CDs. An MP3 disc can hold up to 10 times as much music as a regular CD, so you can transform your 400-disc mega changer into a virtual 4,000 -disc super mega changer!

With the CDP-CX455, it's easy to label and organize all your CDs for instant retrieval and playback. If a disc is pre-programmed with CD Text, the titles will automatically appear on the front-panel display. If not, you can enter titles manually with Disc Memo (and you can hook up an optional PS/2-compatible PC keyboard to make the job easier!). Once your discs are labeled, use Memo Search to scroll through the titles alphabetically or Memo Scan to search by location. And when you find the CD you're looking for, set it spinning with the touch of a button. The changer also includes 8 Artist Files, which gives you the ability to group discs together by the labels you assign to them.

For those with big music collections, you can daisy chain two mega changers together via the Control A1-II jack for access to up to 800 CDs. Not only can you control the two units as one, but the pair requires only a single receiver input, and the second changer's disc titles appear on the front panel of the first. You can even crossfade between the two mega changers DJ-style!

Good library organizer

IGO from Las Vegas on 12/14/2008

I bought a lot of new gear at the same time so I'm still tinkering and tweeking 6 weekends later. I did find an old PS2 type keyboard and I'm looking forward to cataloging the CDs in it. I'm glad this can be done with an external keyboard but why not a USB keyboard conection instead of this hard to find and outdated keyboard? This unit has to be turned off when watching home theatre as the blue light is so bright it's distracting. One huge issue I have with this unit, and an issue it shares with the superior Sony ES SACD SCD-C2000ES is that they both share many of the same commands on a remote. The 400 disc changer is my house wide background player but the ES SACD is my sit down listener yet they both compete for the remotes commands. This is a real pain and if I can't find a way to re-code the power on and power off commands it might the 400 disc library player un-plugged. Now for something positive. It shuffles the materials, finds it and plays just fine and it looks cool in my set-up.



Disappointing quality, 2 units dead in 6 yrs

Damian from Miramar, FL on 12/7/2008

Crutchfield Customer Review (What's this?)

I bought the 300 CD unit about 6 years ago and loved the utility of it. In the pre-MP3 days it was great to have all your music loaded and ready to go. It lasted about 4 years then stopped loading CDs. I chalked it up to just a bad unit. I bought the 400 CD unit about 2 years ago to replace the original. Just yesterday during a party, the unit stopped playing CDs. It refuses to spin the CDs after they are loaded. Bummer for the party. Bummer for Sony component quality.

Crutchfield Customer Review (What's this?)

Really convenient, but be sure to look closely at the exterior dimensions before you buy. This box is huge and will not fit in the same space (length) as the rest of your SONY stuff.



Not what I expected

gatorhater73 from Sugar Grove,Va on 12/19/2007

Crutchfield Customer Review (What's this?)

I have the 300 disc changer and thought this would be a great addition to that but the ability to delete tracks from discs and to play shuffle without repeating tracks have made me a little upset I didn't go with another 300 which I will do next time.



Nice, but usability is flawed

Thomas from Denver on 2/22/2006

The following is an except of a review that I wrote for the CX-450, the predecessor of the CX-455. I downloaded the user manual for the CX-455 to make certain that this essential part was applicable, and that seems to be the case.<BR><BR>For me, the natural way to find the disc that I want to play is to begin by selecting the artist name, and then peruse the titles by that artist. The capability that comes closest is the Artist Mode. From the player, you press the "Artist Mode" button. You use the jog dial to scroll through the list of artist names, and when you find the one you want, you press in on the jog dial. That engages Artist Mode, which changes the behavior of the perusal techniques that use the player's display, so that titles not by that artist are skipped. This capability is useful, but is hindered by the fact that it is tied in to the Artist Mode. The Artist Mode capability is intended to give you a way to play multiple discs by the same artist, with tracks shuffled if you like. You can use it to facilitate finding and selecting discs by a specific artist, but as soon as you select an artist different from the one currently playing, the disc currently playing stops, and the player commences playing the first disc by the other artist that you select. This is aggravating when you want to peruse titles by a few other artists before making your selection. The bottom line is that this player lacks a good way to select a disc by starting with the artist and then perusing the discs by that artist.<BR>



Sony CDP-CX455

Kat from Gilbert, AZ on 1/8/2006

Crutchfield Customer Review (What's this?)

We already have the Sony 300 CD Changer and have really enjoyed it for the past four years or so. It was really nice to be able to then get the 400 CD Changer and be able to connect the two for a library of all of our CD's. I also like the fact that now any CD's that we have MP3's on can now be played in the new 400.<BR><BR>What I didn't like about the 400 is the downgrades Sony has made since we purchased the 300. The remote was much better for the 300 and that was a disappointment since we want the 400 to be the master. Also, with the 300 we got folders to put the CD pamphlets in so that it was easy for someone who wanted to see what we had and pick out a CD. I was really disappointed about these two things, but overall still enjoy the both units.



A Very Happy Customer

Daniel from Pittsburgh, Pennsylvania on 9/29/2005

Crutchfield Customer Review (What's this?)

Having all my music in one place has increased the use of some of my oldest CD's. Before if I wanted to hear a song I would think twice just because of the hassle involved locating it in a massive amount of jewel cases. Now, I just dial it up on the player in a matter of seconds. Did I mention how much space I now have that those unsightly tower racks are gone?



Great for LARGE collections

David from North Yarmouth, Maine on 3/17/2005

Crutchfield Customer Review (What's this?)

These units are great! I own four of them, each one holds 400 disc's and they are all full. Now my collection has grown another couple hundred disc's that are sitting on the shelf so I need another one. The convience is fantastic! No more handling those awful jewel cases. Just dial up an album or tune, hit the button, and there it is in your ears. Really, the reasons for owning these are numerous, if you get one, after awhile you will say, "How did I ever get along WITHOUT this thing!". I know I did.




Hands-on research

Product Research

Inputs and Outputs


MP3 Playback: This unit will play MP3 files recorded onto CD-ROM, CD-R, and CD-R/W discs using the ISO 9660 level 1 or level 2 format, or Joliet or Romeo in the expansion format. The maximum number of folders is 150, and the maximum number of MP3 files and folders is 300. ID3 Tag information will display only when version 1 is used. This unit will display the total number of MP3 files, the total number of MP3 files in the current album, MP3 file name, MP3 file number, and playing time of the MP3 file.

Keyboard Input: There is a PS-2 (also called IBM type) input on the front panel of the player for a keyboard. If you want to use an AT type keyboard, you will need to purchase a keyboard input adapter. Using a keyboard will make naming discs much faster. Power consumption of the keyboard must be 120 mA or less.

Custom Files: The player can store two types of custom file information for each disc:

  • Disc Name: label discs with names up to 20 characters
  • Artist File: up to 200 artist names, with up to 20 characters each, may be entered into memory

More on Custom Files: Custom files are stored in the player's memory. If the player is not used for about one month, you will lose custom file information. Custom files can be erased one at a time or all at once. CD Text information cannot be replaced by a Disc Name file. Deleted tracks are skipped even in Shuffle play and program mode. All deleted tracks can be recovered simultaneously.

Programs: You can create up to three programs, each of which can contain up to 32 steps. A step can be one track or an entire disc.

CD Text: When playing a CD with CD Text the display will show you the current disc title, artist name and track title if it is recorded on the CD. A CD Text indicator lights up on the display whenever the player detects a CD with CD Text information. The remote control has a button marked "Highlight" that will play only the highlights of a CD Text CD if  that CD has this feature (not all CD Text CDs support this feature).  If the CD Text information is available in various languages, you can select the language that the information is displayed in.

Jog Dials: There is a jog dial on the unit for quick selection of discs and a second jog dial on the unit for track selection.

Last Disc Memory (Resume): When the player is turned off, it will remember the last playing disc and the play mode. When the unit is turned on again, it plays the same disc in the same mode (play starts from the beginning of that disc).

Control A1II Jack: There is a control input for synchronized recording and auto function when used with compatible Sony components. This player can control another Sony CD changer with Control A1II (or Control A1) and Command Mode CD3.

Disc Skip: The player has a +100 disc key, which allows you to skip 100 discs at a time for easier access when using the Jog Dial for disc selection.

Timer: The player is compatible with an optional external audio timer.

Advanced Mega Control: You can control a second Sony CD changer with this unit if it (1) has a control A1II (or Control A1) Jack and (2) the command mode of the unit can be set to CD3. To use this feature, the 2nd Unit's RCA outputs must be connected to the RCA inputs of this unit (marked 2ND CD), and the Control A1II jack of the 2nd unit must be connected to the the Control A1II jack of this unit. When the CD players are connected in this way you can load the Disc Names of the second CD player to this unit's memory if the second player has the Disc Name function. You can label the discs of the second player using this unit or change the discs memos which you load from the second player. When you do this you are using this player's memory, so you can not display them on the second CD player display. When you press the play button on either unit the operating player stops and the resting player starts. You can also use:

  • No-Delay Play: Play changes from player to player after each track. The player starts play without a break in sound immediately after the current player ends play

  • X-Fade Play: Play changes from player to player after each track OR at a specified interval of 30, 60 or 90 seconds. When players change the sound output of both players is mixed, with one player fading out and the other fading in

Inputs and Outputs

Rear Panel:

  • Optical Digital Out: standard Toslink digital jack with a plastic cover
  • Analog Out: stereo RCA jacks (fixed)
  • 2nd CD In: stereo RCA jacks; allows you to connect 2nd compatible Sony CD changer
  • Control A1II: two Control A1II jacks for use with compatible Sony components
