Question On Connecting Multiple Sources to TV, DAC, and Power Amp

I'll try and keep this simple and hope I explain myself sufficiently.

We have:

1. Fiber Optic going to the TV Box then out via HDMI to the TV HDMI 1.

2. Apple TV HDMI to TV HDMI2.

I want to connect a Blue Ray DVD/CD Player to HDMI3 on the TV.

The TV Audio Out is TOSLINK type Optical to a Bose System.

I also have a Kenwood KD500 Turntable going to a Kenwood C1 preamp then to the power amp and separate speakers. I'd also like to add an FM Tuner.

I'd like to eliminate the Bose and use one Audio Amp and a pair of speakers.

I have a Pro-Ject Pre Box S2 Digital with USB, Coax, and Optical (toslink style) inputs and RCA Audio outputs that I'd like to feed the TV to.

I don't want to feed the Pro-Ject DAC/Preamp to the C1 preamp but the power amp has only 1 set of inputs.

Should I get a manual A/B switch to select either preamp to feed the power amp or is there a better solution?

Thanks!

THD is not a good indicator of how something will sound.  Things like power supply, output stage, etc. will have a far greater impact on sound than THD.

I understand the logic. My point was that if the THD isn't as good as an Audio Source amp, my mistake on writing Sound Source, and they don't give specs on the phono section perhaps other specs aren't very good as well.

I agree that the THD spec isn't a great way to determine sound quality. Years ago, an audio engineer I worked for used to laugh at the Dr.'s and Lawyers who came in to his shop for mods and repairs. I remember him saying "They can't hear the difference between .001% distortion and .0001%.

Yes, if I go with an AVR I'd like to send the preamp out to a 2 ch setup. But, then I have to contend with what the AVR adds or detracts from the original signal wouldn't I?

As others have said, get one device for home theater and another for two channel stereo.  The amplification in most AVR units is not very good.  Your best bet is to get a "processor" (no amplification) and a two channel preamp that has home theater bypass and use a separate amp(s) for your main speakers.  You could get an AVR that has a preamp option that allows you to bypass the amps in the AVR for your main speakers and use the AVR to power your surround speakers.

This allows you to listen to two channel music without having any of the home theater components in the chain and to share your amp(s) with the home theater processer when using it.

Thanks for the additional input. My LR has 12' ceilings with a cookie cutter center that rises another 2'. I don't plan on going into the attic and installing a multi-channel surround speaker system. Two speakers up front and perhaps a sub if needed.

I want a setup that sounds decent for the TV with more focus on the music (phono, CD, and lossless player, no mp3's.).

Good point on the processor. I'll have to check if these processors with bypass are true bypass or switched through circuitry.

OK, this is getting better. Thank you all for the input and yes, correct me if I go astray.

I think you are trying to do 3 different things.  Have a DAC/Amplifier system, a stereo, and a TV system.  Pick 2 or live with a messy complex system.
