REVIEW: Ray Samuels Audio Dark Star solid state headphone amplifier
The DarkStar was not designed to drive low impedance headphones, any portable solid state amp can drive the low impedance very well. Dark Star has too much gain for low impedance phones even with it's low gain of 11. The DarkStar, with low gain of 11, works great with high impedance phones...- Ray Samuels

RSA The Lightning F-35, fully balanced portable amp Review: 35 more F-35 amps at intro price . . .
F-35 can drive HE-6 to acceptable level but it is limited to the battery voltage as it can not swing more than 16 volts, which is perfect for all hard to drive phones & high impedance but the HE-6. If you want the portable that can swing around 36 volts in balanced then the SR-71B & the...- Ray Samuels

RSA The Lightning F-35, fully balanced portable amp Review: 35 more F-35 amps at intro price . . .
Keith... I use the F-35 with HE-6, it can drive it very well to a very acceptable sound level. Also in balanced it can drive my HD600, 300 ohms with ease. There should be no problem driving DT880, 250 ohms. I have one but in SE & it sounds great & it takes that edge of brightness that DT880...- Ray Samuels
