Dual triodes Class A Line Preamplifier

 

PRE1 Preamplifier born after two years of development. It is the first preamplifier in LAB12

products range and aims to exactly the same target as all our products, to achieve a warm,

musical and most of all realistic sound that remains enjoyable even after many hours of

listening. We achieved to give PRE1 a high class performance, much higher than its price

range. It is a great choice to be combined with a solid state or tube Power amplifier. In both

ways PRE1 will give this known warm, friendly and analytical sound of LAB12.

Internally we use a matched pair of E88cc tubes in a special configuration and a four stages

solid state power supply with more than enough capacity and smart filtering. Dual mono

philosophy and fine symmetry® exists in every stage of circuit and PCB and of course we

use the SRSG® topology in this gear too. Special selected parts like MKP audio grade

capacitors and 1% resistors bring the fine detailed sound and the wider resolution.
