Streamer, Dac,with Pre Amp

The only way to by pass the A8 pre-amp is to use one of the digital outputs. Use the USB or the IIS because they are higher quality.

If you want to use your t.v. with A8 or another DAC use the ARC connection from your t.v. to the DAC or A8.

I thought you can set the eversolo dmp-a8 volume to fixed or something like that not sure what it's called in eversolo?

My Yamaha is a Integrated Amplifier. 

I could always hook the eversolo to main derect on the integrated amp and use eversolo preamp but I was wanting to use the integrated amplifiers preamp 

If you like sound that’s warmer and laid back, TMR has Bryston BDA-3.14 DAC Streamer. With this unit you will probably need to subscribe to Roon as the Bryston Manic Moose is not the greatest user interface ever. But…this is a good sounding DAC and with Roon it should be very nice. It also gives you flexibility to add a good streamer later on and use it as DAC only. It’s worth checking out especially if you can knock the price down a bit.

This would be my choice over Eversolo. Another plus is Bryston customer support is first rate.
