okay i just bought the dd1 a few days ago and i had couple quick questions. When tunning the amp should i use cd test track or downloaded versions on phone via bluetooth. honestly i dont listen to cds im either pluged into aux usb or bluetooth does that mean i should tune my amps while playing the track on my phone using aux usb or bluetooth or does it not matter its all them same???
reason i ask is because aux usb and bluetooth are considerably louder than cd
i have pioneer 4800 bhs
