Hybrid tube-transistor headphone amplifier

The XDUOO MT-601 combines a dual 6N11 tube pre-amp stage with a Class-A transistor buffer to deliver warm tube character and strong driving power for virtually any headphone. It accepts user-swappable 6922 or E88CC tubes for tonal flexibility.

Volume-controlled line output adds pre-amp function

A single line-level output passes the tube-stage signal through the front-panel volume control, letting the unit serve as a preamplifier for power amplifiers or active speakers without extra cabling.

Drives demanding headphones; not a speaker power amp

The Class-A buffer stage supplies ample current for high-impedance and low-sensitivity cans, but the line output is signal-level only and cannot drive passive loudspeakers directly.

Questions about this item

Which tubes can I swap in when the 6N11s wear out?

The pre-amp sockets accept 6922 and E88CC types as direct replacements for the stock 6N11 tubes.

What caps the output when I push the amp hard for hours?

The Class-A transistor buffer stage sets the maximum sustained current available to the headphones.

How hot and noisy does the chassis get during an all-day session?

The hybrid design runs warm from the two 6N11 tubes and Class-A bias, but uses passive cooling with no fan noise.
