Drop Objective 2 Headphone Amp: Desktop Edition (Standard), Black, Standard Gain (2.5 Low, 6.5 High)

BASELINE PERFECT — The Objective 2 Desktop Edition features updates based on feedback from the community.
it’s an ideal baseline reference amplifier, capable of powering everything from IEMs to HD 800s with linear ease.
COMMUNITY-DRIVEN DESIGN — The O2 was made to be an entry-level benchmark performance amp, something the audiophile world had never seen before.
while most were satisfied with purist input, output, and power arrangements, the Drop community wanted more options.
RECONFIGURED FOR THE PURISTS — Drop community members asked for a quarter-inch headphone output, RCA inputs, and a rear-mounted power jack, and we included all three requests in the Desktop Edition.
STANDARD GAIN VS. MEDIUM GAIN — Get the medium gain version if you plan to primarily use this amp with IEMs. If you don't plan to use IEMs, if your headphone has a 300-ohm or higher impedance, or if your source is weak (less than 2V output), opt for the standard gain version.
