General Information
The REFERENCE SERIES from Lake People covers absolutely high-level audio products with outstanding features, best technical data and perfect craftsmanship.
The headphone amp HPA RS 08 use the highly regarded and reliable technique of Violectric HPA V100 which is known and honored for its powerful and neutral sound. In case of HPA RS 08 four internal amps (left in phase / left out of phase / right in phase / right out of phase) are at work to support the connection of BALANCED HEADPHONES and to enable the typical wide sound stages. Of course all other features of our famous headphone amps can also be found here. In combination these are second to none:
Lowest Noise
because of low internal gain. Therefore the self generated noise from the amplifier is not audible.
Highest output voltage swing
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 !!
Highest output power
because of powerful amplifiers able to deliver much more current a headphone needs. Therefore best suited for low impedance headphones and even magnetostatic cans !!
Highest damping factor
through lowest output impedance. Therefore best suited for full control even over critical headphones with the garantee to have flatest possible response.
But there is even more !!
Pre-Gain
means a 5-times adaptive gain setting on the back panel to customize your amp to match perfectly your source and your headphones.
The flexible input/output architecture
- You want to connect your source passively to following unit because you don´t want
to switch on HPA RS 08 when you want to hear your speakers?
No problem, set the internal jumper to “Passive Feedthrough”.
- You want to connect the next unit in an active way because you know
that this is technically better?
No problem, set the internal jumper to “active feedthrough”.
- You judge the abilities of HPA RS 08 so high that you want it to control
your power amp or active speakers?
No problem, set the internal jumper to “active feedthrough with volume control”.
Ingenious ? Ingenious !
