O2+ODAC is an Objective2 headphone amp with integrated ObjectiveDAC. This high performance amp+DAC combo ships fully assembled, tested, and ready to use. Includes USB cable.
Our Objective2's are assembled 100% in accordance with NwAvGuy's default, high-performance specifications.
Objective2 achieves vanishingly low THD and noise performance for audible perfection.
O2's extremely low output impedance ensures transparent frequency response for all headphone loads.
At over 600mW, Objective2 provides enough output power to drive all dynamic headphones on the market with authority.
ODAC's audibly insignificant jitter (-106 dB) proves that reference quality D/A conversion can be affordable!
You'll enjoy O2+ODAC's 24-bit audio. Impressive dynamic range and low noise give perfect clarity.
Both the amplifier and DAC stages of O2+ODAC perform within +/- 0.1 dB of ideal frequency response.
Please note that O2+ODAC is an AC powered device and does not contain batteries. Power adapters are sold separately, as we ship worldwide. Be sure to select one of the following:
Default gain levels of Objective2 are intended to work well with over 95% of headphones on the market. We use the stock O2 with headphones as low as 16 ohms @ 1 dB/mW, and as high as 600 ohms (very high and very low efficiency, respectively). There is no reason to alter stock gain unless you regularly listen at extremely low volumes. We can set custom gain of 1.0/2.5x upon request, or you can easily perform this change by removing two resistors.
