So I have several amps with headphone jacks, one of them is a yamaha thd amp, with 1/4 " phone , 1\8 aux, and usb connections,... currently I'm using an older audio box usb, all connected to a new mac with studio one 3 pro,...
Headphones are beyerdynamic dt770 pro at 250 ohm.
I want to use the hp4.
Basically I needed to boost the signal with an amp(HP4),for the headphones because of the high impedance..., since I have to go thru my audio box usb, Im not sure how to get the amp(yamaha thr)to connect to the audio box or the hp4.
My question is will the hp4 work with the amps & the audio box usb, what cables do i need & what's the cable path.
my best bets probably is just to get the 80 ohm version of the headphones and forgo the whole mess...
