JDS Labs Assembled Objective2 Headphone Amplifier

Meant to be married to the OL DAC, the O2 headphone amp matches it in shape, size and simplicity. What's neat about the O2 is that JDS Labs allows for some simple customizations—you can choose the headphone jack size (3.5mm or ¼”), input type (RCA or...

I read about this device online and the reviews were very positive - so positive that I jumped in. It was my first headphone amp — I purchased my second, the fiio a5, shortly afterwards. Take into consideration I am an amateur audio geek... It is just...

I bought this to listen to my vinyl on my Hifiman HE-400 phones. It does a great job of driving them with a very neutral and I can hear detail that my £5500 worth of amp and speakers don't pick up. The JDS Labs would cost $191 shipped to the UK. I...

The Objective2 is my first amp along with my beloved HD600 headphones. Here is my review after my experience with it for several months. Intro : I am an 21 year old Engineering student living in a small town in India. There is not much...
