The Bottlehead Reference System
BeePre2 and Paradyne were designed with the same goals in mind: high headroom, low noise, and a direct, unforced presentation. Together, they deliver power and warmth without effort. With a conservatively rated 35 watts per channel, Paradyne brings nearly three times the output of our next most powerful amp, and BeePre2 is built to drive it properly.BeePre2’s low output impedance and ample voltage swing give Paradyne exactly what it wants at the input, with control and clarity intact. The result is a signal chain that stays stable from source to speaker, preserving dynamics, tone, and space without strain. No workarounds or mismatches. Just a front end and power stage operating as a system. Grab the combo for a 15% discount.
Note: volume discounts do not apply to packages like the Reference System or MoreSex Combo.

Bottlehead's Flagship System
Upgrade your sound
BeePre2 is an impeccable preamp when built stock. But we offer a couple upgrades to make it even more incredible.
Our Bee2Quiet Stepped Attenuator upgrade replaces the base kit's potentiometers with coarse and fine attenuators stuffed with high-quality Dale resistors and adds a constant current source. Once that's installed, some builders install the Hybrid Shunt Regulator and Low Impedance Balanced Output to reduce startup thumps and convert one of the unbalanced outputs to a low impedance XLR.
Yes, you can do it!
