    Hi guys
    I have a new TV with only digital outs for sound, USB, HDMI and Optic. My amp takes only analogue inputs (RCA). I can buy a DAC but it occurs to me that I could possibly use the USB INPUT on my MARANTZ CD player and utilise the DAC from that. Has anybody tried this? Does it work and will there be sound sync problems.

    Thanks

    Your TV won't output sound via USB.
    Use the headphone socket if it has one.

    the usb on your tv is to allow you to plug in a usb drive with media files and play them back, video clips, music, pictures.

    OK Thanks chaps. That's useful info. It'll be an interesting exercise to compare the sound using my current TV, analogue out into a stereo amp. So I'll be trying headphone socket, usb to the CD player, then analogue out to the amp. I wonder if I'll notice any difference in sound quality and/or speach-picture sync.

    Why on earth do you want to connect a CD player to your TV?...unless you mean a DVD player?

    The idea is to use the CD player as a DAC from TV to Amp (because my TV doesn't have analogue output and my amp has ONLY analogue inputs.

    Why not just buy a new amp, will probably be cheaper and a lot less complicated.

    My word that's a brilliant solution, but where's the challenge? - and if you'd care to contribute to replace my Musical Fidelity beast I'd be happy to receive it.

    Ive never seen a TV anywhere that will output to a DAC from its USB port.
    That is not a function on any TV.

    With TVs audio output options are...
    HDMI ARC , you need an ARC capable receiver for that.
    Optical output, you need an amp or soundbar with optical input
    Analog from headphone socket or RCA outputs if it has them.

    Never USB.

    “So I understand. I've learnt something from my original question. That's why I'm going to try the headphone out to USB as per the suggestion from JayCee. If it sounds OK that's good. If it doesn't, I shall have to think about a dedicated DAC between the telly and the amp. The reason for this attempt is the belief that the DAC within the CD player is probably better - or as good as - than most of the mid-range dedicated DAC units out there. However, if anybody has alternative suggestions I'm happy to hear them. Outside of buying a new amp!”

    That still doesnt make any sense.
    The DAC in most CD players is not accessible to other components.

    What model of amp?
    What mosel of CD player?

    Post that info and we will tell you what options you have.

    CD player is a MARANTZ CD6004. It has a USB input for IOS devices (which I have successfully used) - and an analogue output option. I am to test its ability to take and convert a signal from my TV via the headphone socket. If it works and the sound is decent, that's good. If not I'll find an alternative solution. AMP is Musical Fidelity m3i feeding a pair of B&W CM8'S.

    the headphone output on your tv is already in analog, and will come put ona 3.5mm jack most lieklymeaning you cannot connect it to the usb port on your Cd player. even if you could, it's already in analog and doesn't need to be converted.

    connect the headphone output on your tv to the analog input on your amp and you are done. just mind the volume levels

    mossym. My brain must have been in neutral all this
    mossym, my brain must have been in neutral all this time. Many thanks for tuning it in. I was looking for complicated solutions and the answer is so b....y obvious. Many thanks indeed. I'll give it a go as soon as I can. Cheers indeed. I owe you a beer.

    I suggested you do it via the headphone socket in post #2

    Indeed you did JayCee, but unfortunately I had interpreted that to mean go from Headphone socket to the the USB port on the CD player. Just goes to show you can't be too old to stop thinking. Again, my thanks.

    I'm happy to announce that plan JayCee and mossym works. I've tried it on the TV I'm planning to replace (which has analogue outputs). The audio levels out of the headphone port are significantly lower than through the standard outputs, I'll think about whether I can live with that.

    Check your TV's sound menu for a headphone level control.
    Most Panasonic and Sony models have that option as do most brands with the Turkish Vestel-based chassis.

    Sorted! On this issue. Does anybody know what, if any, difference an external DAC would make? I realise that there are some supposedly excellent DACs out there which would take the Optical output from a TV but if the digital output from the TV, i.e. the source, is bit rate limited limited, what genuine difference would a sophisticated DAC make? I hope somebody is following my line of thoughts, I'm probably not expressing myself too well. Overall would optic to DAC to Analogue RCA be superior in sound to Headphone jack to RCA analogue all the way?

    I doubt you'd notice any difference to be honest.

    Fair chance you are right. However, after reading a positive report, I've ordered this on-line from Amazon. If, as I suspect, I notice no improvement it can go back. I'll let you know how I get on.

    JayCee, I think you may be right. I cannot notice a discernable difference. I'll leave it a while to see if it needs settling down. I have the headphone socket feeding into the amp AND the Optic going via the new DAC so that I can switch across at will. I'll see how it goes.
    Regards
