microZOTL Preamplifier

Will the headphone output on the microZOTL Preamplifier work with my "hard to drive" / "hard to pair" headphones? (Sennheiser HD650, HiFiMAN HE1000, HE-6, HD800)

In some cases, such as the HiFiMAN HE-6, HifiMAN Susvara, or AKG K1000 which has notably low sensitivity and thus requires several watts to power adequately, the microZOTL Preamplifier will not give you a satisfyingly loud and full listening experience.

Since the unique circuit of LTA amps reacts very little to different impedances, it is mostly a matter of sensitivity when it comes to which headphones the microZOTL Preamplifier headphone output works well with.

Whether it can "drive my headphones" often just means "will I prefer how my headphones sound with this amp?" We've read many accounts of people thinking their HE1000 or HD650 has never sounded better than with their microZOTL Preamp. I've also read one or two accounts of people saying the opposite.

We don't know what you like, but we do know that we've read far more mentions of the microZOTL Preamplifier sounding good with all kinds of headphones than not.

While we’re at it, we should also note that the headphone outputs on the Z10 Integrated and Z10e electrostatic headphone amp are more powerful and may work better for you if you have less sensitive headphones.

Is the dedicated microZOTL Preamplifier a better preamp than the MZ3?

The preamplifier audio circuit in our reference microZOTL Preamplifier is identical to the one in our MZ3 headphone amp / preamp / integrated amp.

So, why would you buy the more expensive microZOTL Preamplifier over the MZ3?

The dedicated microZOTL Preamplifier has more inputs, a tape monitor section, balanced XLR inputs, and is in a standard rack-ready chassis.

Full disclosure: the headphone circuit in both the MZ3 and the microZOTL Preamplifier are identical as well.
