It's a decent amp, especially for the price. Some noise at 80%, but most amps do that. It can drive my DT990 600Ohm with boost, so it's not bad at all. I mainly use a Grace M920, but the Objective 2 is paired with either Xonar Essence STX's or Titanium HD's with LME49720NA op-amps. The next jump is an amp and DAC into the hundreds or thousands, but with some used parts and easy upgrades, you're in easy audiophile territory.
