A question about sound

[nick1000000]

Okay, this may be a stupid question but...I play my audio CD's using my DVD player. It is connected via Coax to my preamp. Am I actually changing anything when I choose the "bypass" mode on the preamp to get 24-bit/192kHz audio? Do I need to use RCA cables to get the effect? I know the Coax delivers digital data to the preamp and the RCA delivers analog.

A CD is 16/44.1 and cannot ever be 24/192 unless the receiver/pre-amp is upsampling on the fly. Using a digital coax (s/pdif) connection you cannot get 24/192 to the pre-amp even if were that way natively on the disc.

As best I know, bypass is to bypass the digital circuits in a component, used with analog in so it is not re-digitized and then converted to analog, again. So, if you send a digital signal, no need to bypass. It may turn the digital path off altogether or just not be effective if the pre also detects a digital signal with no analog input.
If you do both, then one or the other will happen

When i play a CD and hit bypass it says PCM 44.1K and switches to 2.1 or 2.0 depending if I want my sub on. What is the pre doing when it says this?

I don't know, I'd have to read the manual for it. Does bypass switch between 2.0 and 2.1? If so, then bypass means bypass the bass management circuits and send a full range signal to the front speakers.

So where does 24/192 come into play? I inferred from the original post that bypass switches to 16/44.1 whereas if you do not bypass it plays 24/192 (which means it is upsampling on the fly).

I use Digital Coaxial cables for all my ANALOG signals. Digital coaxial cables are great for carrying ANALOG signals.

However, for ANALOG the main thing is not the cable type, but where that cable is connected. For "bypass" you probably need to connect that to the ANALOG input (like CD Input), instead of DIGITAL input.
IMO BYPASS means that the Pre-Pro is not using any internal processors (including DACs). So you need to hook the signal to the ANALOG input of the pre-pro.

I use one coax coard to plug into one CD input when I have two inputs, R/L?
I guess my real question is, theoretically would I heard better sound using RCA plugs than a Coax using the option to bypass?

Only one way to find out. Should take you all of 2 minutes to know. regarding cables, anything that looks like an RCA cable is.

Digital coax=rca=composite=component=etc... they are 75ohm rated (usually, sometimes lower I guess for certain interconnects, better bass or something...) Just use any rca cables and find out! Tell us what you think...

No. You use two coax cables to plug into two CD R/L inputs.
What I'm saying is that the digital coax cables can be used like the ANALOG RCA cables. My rationale is that digital coax cables are more robust than the usual thin plain analog RCA cables. Since I can buy them at monoprice for so cheap, why not get all digital coax cables to use as analog. I know. OVERKILL.

Bottom line, use TWO analog RCA cables or TWO digital coax cables and plug from the CD player's L/R output to the pre-pro CD L/R input. Then you can use the Bypass mode.

I'll try these options thanks.
