As the title implies I'm looking for a small form factor amp that would include a usb dac and a headphone section...I don't need huge power output...class D is totally fine... Dac I would like to be AK or Sabre base... tired of BB stuff Headphones I will be using are Grado 60's...AKG 240 Studios... and AKG K550's... I had a Teac AH01 that canned on me... and to be honest the dac was only ok... I've taken the Topping TP30 out of my garage for the moment to use... headphone section is definitely no great LOL!! I would rather not spend more than a few hundred Canadian... so if anyone has any ideas for me I sure would appreciate it!! Thanks!!
