A classic from JDS Labs Rev B

Posted

Pros: Sound quality, build quality, customizable, fantastic amp section

Cons: Dosen't support the highest bitrates, amp section stronger than the DAC section

This is a review of the JDS Ojective2+ODAC Rev B amplifier and DAC combination.  The JDS Ojective2+ODAC Rev B (O2/ODAC) was sent to me for free by JDS Labs for the purpose of doing this review and including it in my recently started $250+ amp/DAC comparison thread.

Posted

Pros: Small, Transparent, Open Source, DIY Capable

Cons: Outdated

Intro:  JDS Labs, Is an American company based in Collinsville, Illinois. They make headphone amplifiers & DAC’s. Mr. John Seaber is the man behind JDS Labs. We might remember JDS Labs when they produced the popular cmoy-BB amp & later on, their Objective2 which was a game-changing amplifier. JDS Labs also have their own products: C5/D Portable amplifier/DAC, Element desktop Amp/Dac along with their Cmoy BB amp. My profound thanks to Mr.John for arranging a sample unit for my evaluation.   JDS Labs O2 was my first ever headphone amplifier in early days of my Head-Fi days. Enjoyed it a lot, had a wonderful time with it. O2 holds a special place in my ears.  ...
