Lab12 Mighty Tube Power Amp

Class A, Single Ended Power Amplifier

This Class A, Single Ended amplifier can cooperate gratefully with any preamplifier on the market and it is the perfect match for TRUE or HPA. Mighty has the ability to nail you down on your couch and make you listen all your music collection again. All the power you need for a normal range pair of speakers is here but the most remarkable point is that you will receive a fluid, wide and addictive consonant sound with any choice of music style.

As always, Lab12 choose a well-studied, stable design with their first priority being the enjoyable sound. They chose the best sounding parts and they made more listening tests than you can imagine, to finally achieve this lovely sound character.

The luxury paint of the 5mm aluminum face plate exists on the output transformers covers too, so the overall feeling of the device is really attractive and eye catching.
