A Lyrical Tale of the Beauty and the Beast

 

Thivan Labs artfully combines a very distinctive and minimalist, highly functional and bold Bauhaus aesthetic with an unmistakable sonic identity … one that, with disarming honesty, infuses the “system equation” with a rich and lyrical narrative … a sonic narrative that is beguilingly poetic in cadence, such that the more you listen, the more lyrical the musical journey becomes !

The Thivan Labs flagship GRAND PRE includes 5 inputs and 2 outputs, plus an additional fully balanced XLR output, enabling easy and flexible connections with other devices. 

 

The Grand Pre uses an OPT, which effectively isolate the amplification output stage.

It has a more detailed and musical sound thanks to the use of separate voltage sources for different amplifying stages. This also allows the noise index to reach its lowest level, and results in a quiet and pure background with enhanced sound detail retrieval.

 

Other Highlights :

  • 1000 step Volume control @ 0.1dB per step

  • Minimalist circuit design with high quality components.

  • Two 12AU7s are used for input stage amplification and two 6SN7 for the Output

  • The 6SN7 tube was selected for the output to improve sound detail and body, effectively supporting sound stage performance
