The V281 was our most popular headphone amp every! The Final Edition has a special front panel with a silver polished edge and the internal Xmos USB DAC option is included for free!

The HPA V281 was developed with the target to enable ultimate transmission quality for low- , medium- and high-impedance headphones.

Due to its specific, variable, low-noise and low-distortion circuit design especially optimised for dynamic headphones, the HPA V281 fulfils even most sophisticated demands.
HPA V281 is one of the few headphones amps made in Germany offering a balanced headphone output !!
Furthermore HPA V281 offers selectable inputs and an output management.

because of low internal gain.
Therefore the self generated noise from the amplifer is not audible.

through 60 Volt internal operating voltage.
Therefore best suited for high impedance headphones.
Over 90 % of all headphone amplifiers in the market offer not half that voltage !!

because of powerful amplifiers able to deliver much more current a headphone needs.
Therefore best suited for low impedance headphones and even magnetostatic cans !!

through lowest output impedance.
Therefore best suited for full control even over critical headphones with the garantee to have flatest possible response.

Introduction to Lake People

Established in 1986, we have since become your partner for professional audio electronics. Following our motto “tools - not toys”, we achieved highest reputation during the past years amongst our customers. These are private studios, broadcasters and TV companies. Also airports, congress and exhibition centres count on the reliability of our products made in Germany. This all began under the roof of Rosgartenstrasse 13 in the city of Konstanz. Here, three young guys started with the development and manufacture of limiters and noise gates but not too successfully in the beginning. The commercial survival on a very low level was made possible by the production of headphone amplifiers. From 1989 on, the production range was extended to level matching and balancing amplifiers such successfully, that it came essential to move to larger premises.

Since 1991, the new address read: Haidelmoosweg 52. Due to the developement of the first german 20-bit A/D and D/A converters in the beginning nineties, the name Lake People resounded throughout the land. Suddenly, the company was regarded as a high-tech brand, with a highly positive effect on its public reputation. The growing know-how led to many new products in the analog and digital domain during the following years. Although some projects turned out to be flops, most devices met the customers' requirements, with the effect of continuous growth of the company. By the end of the nineties the 140 m² of Haidelmoosweg 52 went cramping.
Again, a move to new premises came necessary. As it was obvious that rental facilities would not meet the demands, we decided to put up our own building. The company site was constructed in 2000 in a new industrial park in Konstanz, Turmstrasse 7a, just a hundred metres from the lake. Also in 2000, Lake People was transformed into a Ltd. company.
