Lab 12 PRE1 Preamplifier

Lab12 Class A Tube Preamplifier


PRE1 aims at exactly the same target as all our products do, 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 solid state power supply with 4 regulation stages offering smart filtering and more than enough capacity. Dual mono philosophy and Fine Symmetry® exist in every stage of the internal circuit and of course we use SRSG® topology in this gear too. Special selected parts like MKP audio grade capacitors and resistors with 0.1% accuracy also contribute the production of the final detailed sound and the wider resolution.

PRE1 offers five analog inputs and two preamplifier outputs, so you can easily drive a bi-amping system or a power amplifier and active subwoofer(s) with no problem. Input selection can be performed by the on face rotary switch or by the remote control.

PRE1 can be purchased in our standard Matt Black or Pearl White colors but can also be available in a custom color of your choice.

We have chosen KT-150, the king of octal tubes, to base our new Single Ended power amplifier on. Suono offers you the magical sound of class A with all the power you need.

Combining the best of the best to create extraordinary audio gear

We get the best from KT-150 by combining them with our finest goods. Power and output transformers and all other parts are selected and perfectly matched as class A amplifier requires. The 300 watt power transformer offers effortlessly all the power Suono may requireneed. Big Nippon capacitors and separate chokes for each channel regulate and filter the voltage, supplying the amplifier with unlimited power. Audiophile coupling capacitors also exist to add a transparent flavor between the Russian driver triodes and power pentodes. The outcome is full and tight bass, precise and natural midrange and crystal clear high frequencies.Sound that will never make you feel bored or tired.

Adapt your amp to your equipment, taste and mood

You can instantly choose between Triode and or Ultra Linear mode and tailor the sound in the mood of the moment by simply toggling the switch. Don’t even worry about the impendence of your speakers, power transformers offer two outputs for perfectly matching with 4 or 8 Ohm speakers.

For your eyes only

Nissei VU meters exist again in the face plate bringing to your eyes similar emotions with your ears. Our new Matt Black or Pearl White colors on the face plate and transformers’ covers contribute to the overall sense of a high quality product.
