EARMAX-PRO Headphone-Amplifier by Brocksieper

You enjoy music with headphones? If so then make sure to try the EARMAX made by Brocksieper. This little tube driven Headphone-Amplifier will be your ultimate listening experience.
The most direct and natural listening experience is waiting for you.

The EARMAX series will be your ultimate listening experience with pure tube design (Class A single-ended triodes, output transformerless (OTL) design). These masterpieces are handcrafted in the small manufacture of Stefan Brocksieper. The EARMAX gained worldwide reputation as one of the best, probably the best, tube headphone mplifier ever made. The EARMAX opens new dimensions and astonishing details which are amazing even for the owners of reference class phones.

specifications: Brocksieper EarMax Pro
Tube headphone amp for dynamic phones. OTL design Class A triodes technology, external power supply.
All tube circuit with miniature double-triodes vor signal amplification and output stage (ECC81 and E88CC/6922).
All tube tested and selected by Mr. Brocksieper personally. 
All Brocksiper devices are completely `Made in Germany´, in small series manufacturing.
Each amplifier is tested, measured and burned-in prior to shipping. 
The EARMAX can handle open circuit (no load/phons connected) as well as it is almost perfectly protected against shortage.

* Note: 
This unit can be used with all dynamic headphones with impedance ≥ 35 Ω for maximum performance with the EARMAX PRO we recommend to use phones with impedance from 200 Ohms or higher. 
For lower impedance phones (especcially <60 Ohms) we highly recommend the EARMAX Silver Edition.

other products by Brocksieper:

EARMAX Silver Edition: 
- higher volume with significantly upgraded external powersupply
- especcially designed for dynamic headphones with low Z (min. impedance 16 Ohm) or lower efficiency

PHONOMAX by Brocksieper:
