K&K Audio imports and sells Lundahl audio transformers to Do-It-Yourselfers. We also sell high-end audio kits that incorporate Lundahl Transformers.
Enjoy the sonic benefits of transformer-coupled high-end audio electronics. Ever wonder why the old recordings from the 50s and 60s sound so good? Well, one of the reasons for this is the presence of transformers in the signal chain between the microphone and the recorder. While it is popular “market-speak” to talk about the excessive phase shift and limited bandwidth of transformers, the ears tell a different story. Lundahl transformers are world famous in the pro audio business for their quality. They are used in high-end microphones, microphone preamps, and mixers. They convey the full harmonic structure of music to the listener.
As a DIY builder, you now have access to Lundahl quality for your own designs.
We sell the full line of Lundahl transformers suitable for the construction of high-end audio preamplifiers and amplifiers. In addition, we offer simple kits for audio building blocks, such as MC phono amplification and plate or cathode current sources. We can assist you with your design and suggest alternatives to meet your amplification needs. K&K Audio publishes sample designs to illustrate the application of Lundahl transformers in amplifiers and preamplifiers.
The K&K Audio kits have been developed to provide building blocks for DIY audio projects. They are designed to work together with Lundahl transformers, allowing DIYers to construct state-of-the-art audio equipment. They vary in complexity, but always include detailed instructions to make construction straightforward. The upscale components used in K&K Audio kits have been selected for the best sound/cost ratio.
We design and manufacture custom high-end consumer and professional audio equipment to your specifications. Of course, we employ vacuum tubes and transformers in our designs, because we believe these to provide the best, most musically satisfying performance. However, we are also not blind to the advantages offered, in some applications, by solid state devices, and use these where they are sonically warranted. Our particular point of view is aligned with the “tubes as accurate, musically satisfying amplifying devices” way of thinking, rather than the “tubes used to warm up cold digital sound” philosophy.
