To use or not to use, optical, coaxial,XLR RCA.

I have a Teac TN 300 turntable it has a USB port on hack, that is to put LP to flash drive? As well I have a USB port on front of my newer Marantz 6006 CD player, that is for playing from a flash drive? or putting CD to Flash?

While I am being shamed by my ignorance, are optical outputs of my 6006 CD player better to use to my preamp than the RCA, or are the Coaxial ports better to send to the preamp?

Someone please help me get over my memories of my 4 and 8 track tape players and understand the "Gig of today".

The USB port on the back of the turntable is to transfer the signal to your PC or MAC. It requires a cable. I assume when you plug in the turntable into a computer and turn on the TT, a window should pop up asking you if you want to play the record or store it.

 

The port on the front of your Marantz is to plug in thumb drives.

 

Optical connections are nearly always inferior to coax. So use coax for both connections.

Not meaning to be rude, but why not join the club, and try each, and let your ears determine which sounds best to you. That’s pretty much what all of us here do. What sounds best in your application could depend entirely on your components.

You have to read the directions for each piece of equipment.  USB ports are often for maintenance--adding a firmware update.  I remember one Streamer that I really wanted to use a USB out and the usb on the back was for firmware in.  

So nobody here knows the answer to all these quetions.  Generally you can now google the manual for a piece of equipment. You can figure it out.

Great answers, thanks, I will bypass the optical, go for trying my old RCA on my new set up first. I am getting an Anthem STF integrated and a second Anthem STF power Amp. for the second pair of speakers.  The STF integrated has a Room Correction digital process system inside and likely works better processing digital signals.  The AES/EBU port on back looks like an XLR, but is a single port, not L & R.   My lack of understanding of cables prompted me to ask.  I guess a Coaxial cable has ends like an RCA, but a coaxal shield to stop EMF.  I assume the better RCA cables that are shielded are not the true "Coaxial" digital cable and I need to get the true Coaxial cable, not just a shielded RCA?  

Digi cables have nothing to do with shielding. Just 75 ohm coax terminated in RCA or BNC plugs. An analog RCA analog cable will often work but they are not purpose built. Coax and digital cables are NOT the same.

Go back to your Lear Jets.

The AES/EBU port on back looks like an XLR, but is a single port, not L & R.

If you're going to use the AES/EBU XLR connection, make sure the cable is rated for AES/EBU service, and is a 110 ohm cable.   

 

 

dpop, thanks, the 110 ohm spec is clear to me now, if I use the XLR port marked AES?EBU, I will make sure the 110 ohm rating is present. like the Coax using the RCA, the AES/EBU uses the XLR end, but the cable between ends is different/better.  

I know nothing about Lear Jets, or electronics, I am a retired water professional. Music lovers can love good stereos, and be at a loss for specs & DOS type glossary.  I was wanting to avoid spending money on a cable that was not needed.

You mentioned 8-tracks, and I believe William Lear and Learjet Corp. designed the 8-track tape.

In this hobby, we audio-enthusiasts try different combinations of cables and equipment. We're constantly in search of the best audio reproduction we can achieve with our gear. Many of us simply use our ears to determine what sounds best to us in our environment. It's all very much a learning experience.  

dpop, I did not know that, thanks, I will make a reference to that someday as an OMG!  Well I will likely start with my RCA, then swap to the Coax, and where I can I will use an XLR.  After putting 10 grand + into the 2 new Amps, I guess I am not really in a hurry to up fit cables anyway, I will take your advice and "join the club".

Thanks, Greg

That single AES/EBU digital XLR actually contains L&R stereo audio.

Such a cable did not come with the integrated amp, having that port, I will read the manual to see the advantages of that one cable vs the pair RCA or one coaxial that go to the 2nd. power amp. I am using 2 sets speakers, one set 4 ohm, other 8 ohm.  Did not want to use the intenerated amp down to 2 ohm, even though it is listed in the specs as 550 Watts at 2 ohm.  I will just start using RCA L & R.  I am assuming I will want to use the AES/EBU if I get one.  There are a couple power cords flopping around back there.  I do not have shielded power cords. Are they worth it? I can keep a few inches between all cables as it is, and only cross, not side by side the cables.     

Hold it. You bought a $200 turntable with an internal Phonostage? And $10,000 of amps. Ok, we need to talk.

 

While you must carefully choose your components. But a general rule of thumb would be: Turntable $5K, Phonostage $5K, preamp $5K, amp $5K, speakers $12K. This kind of thing puts the fidelity of components in approximate synergy and equal footing. If you also have digital: streamer $5K and DAC $5K.
