Has anyone tried using this with their fostex th-x00? The fostex has a low impedance that's below the rated range of the amp. Would I still be able to use it?

hoangr6A tube amp for low impedance headphones is less than ideal. At its core, a vacuum tube (valve) puts out a lot of voltage and not much current. That trade-off is what makes vacuum tube amplifiers good for high resistance headphones (150 Ω +) that require higher voltages to drive their more finely wound coils. Those Fostex headphones are listed at 25Ω per Massdrop, they need a lot of current but not a ton of voltage. That demand is best accomplished by a solid state amplifier. If you absolutely must have something with a tube, look for a single or twin tube hybrid amp that uses it tube/s for the driver and not the power circuit.

MotologistThanks for explaining why. Really helped me refine my amp search
