Which DAC is being used with Bluetooth?


Might be a silly question but when I Bluetooth from my phone to my Cambridge integrated Amp Cxa80, the Dac that is being used , is from the iPhone still right? I have a Wadia 171i transport that has a digital out to the DAC In The amp but the sound quality from the Wadia plugged into the amp just sounds slightly better than the Bluetooth option. I’m using a fairly inexpensive no name brand optical plug from the Wadia to the amp... would upgrading to a carbon AudioQuest coax cable from the transport to the Amp make a more noticeable  sound difference? (I have an AudioQuest NRG 3 Y power cable coming in the mail for my 1st power plug upgrade, hoping for sound improvement there too.)

My rig is CxA80 cambridge intregraded 120 watt to 4ohms amp, Dyanaudio DM 3/7 towers, Wadia 171i transport from
 the phone to the dac into Amp, Shunyata venom conditioner plug into $10 power strip with no surge protection.... ( surge protection is from the Shunyata plug) and a low grade Klipsch 12 in Sub( like $250 range from Frys, forgot the model).
Thanks for reading and any advice you can send my way.

It sounds better because the wired connection is just a better connection. Bluetooth is about convenience more than sound quality. Also Wadia makes high quality digital gear.
Bluetooth would send the signal to a wireless receiver then to the Dac in your Cambridge the Bluetooth wireless signal is digital not analog.
