    Hey Gang,

    I am planning on getting the CX455. Since MP3's play only out the analog out, I plan on connecting both the optical and analog to the CD in on my DA777ES receiver. Since it can auto select the source, has anyone tested to see if it really will auto switch.

    Does not make much sense to me, if I have both CD's and MP3's on shuffel, to have to manually switch my receiver.

    I have heard that the CX455 only mutes the optical, so the receiver cannot auto switch.

    I hope someone has tried the above setup, and can confirm just how it works.

    Thanks
    Bob

    I can absolutely confirm that the receiver will not auto-switch.

    I have the 455 connected to a new Sony STR-DA4ES receiver, and previously had it connected to a Sony STR-DB830. Neither would auto-switch. I ended up using two different inputs on the receiver: one (re)named to "400 CD" and one to "MP3 CD". The former used a digital connection; the latter analog only.

    The reason that the receiver will not auto-switch is that the 455 does not turn off the optical output when playing MP3's. Instead it just sends no data through it, even though it is still 'lit'. My SCD-CX755 Super Audio CD changer, on the other hand, will turn off the optical output when playing a SACD, and turn it on when playing a normal CD. So auto-switching (analog for SACD & digital for CD) works just great with it.

    The 455 has numerous quirks. This is just one of them. Did you ever notice that it does not respond to the system-off command from the remote? It also will not respond to a discrete on or off command for a CD player (which are not availble on the original remote, but programmable into universal remotes like the pronto, etc.). This makes it impossible to reliably turn the unit on or off, because you can only use the 'power' button. You don't know for sure whether the player caught the signal (if in another room) and you can't setup a macro in your remote to turn off all components, because if it's already off and you hit 'power', it turns on! Cripes.

    Aaron,

    So I assume when you play a MP3 disk, you have to switch your Receiver's input? That means that your cannot mix shuffle MP3's and CD's right?

    Also, how long is the average quite time between songs when you set the player to shuffle? I am trying to decide if I need to get two units, and then get Nirvis Slink-e unit with their PC software to fully control the units.

    Thanks

    Related question, hope you guys can help...

    My Sony CD changer is connected optically to my Sony receiver. When it was previously connected using the analog output, the receiver would automatically go into CD mode when the CD player began playing a disc. Is there any way to have the receiver now default to the optical input I've chosen when a CD plays?

    Thanks...

    Angelo,

    Not sure about your exact receiver, but I know on my 7ES you can link(pick) either the optical or analog to the CD input. Some even outo select depending on the signal. It sounds to me like you have the default for the CD input set to analog. Flip through your setup manual, it should be there somewhere.

    I am using the CX455 with a STR-DB940 but I use 'Analog Direct' for both normal CDs and MP3 CDs because I don't
    like the extra 'Bass Boost' which gets turned on when
    using most other soundfields (2CH, AFD, etc).
    Anyone know any way to turn it off??

    Also, I have problem with some CD-TEXT CDs which used
    to be read correctly with my old CDP-CX355 but the CX455
    just ignores the title and tracks for most CDs!
