Upgrade for the analogue board

The new Linear II mainboard is equipped with the improved components of the Linear SE board and built using a special low-impedance technology (low-Z copper) which raises the price of the naked PCBs by a factor of about 10. But the effort is worthwhile. This technology results in even better dynamic values, but above all it produces once again a significant increase of the sonic performance: transient response and spatial imaging are even closer to the original.

Here’s how

Download the order form. Print it out and send the filled out form together with your device to the given address. Within a few weeks you’ll get your modified device back and can pay conveniently by invoice.

Reviews

Studio Magazin

"In my opinion, the Linear headphone amplifier by Lehmannaudio belongs to the reference class of its kind. It creates a relaxed, open, neutral and detailed acoustic image which will hardly allow any fatigue effects to sneak in."

"When I found Lehmann Audio on the internet, my decision was rapidly made, and the Black Cube Linear sounds great, it’s a basic element in the flight case when we record outside Motor Music."
