sennasound – It's Serbia's newest brand by Nemanja Cokic, son of Trafomatic Audio's Sasa Cokic. With a phono stage, preamplifier and power amp in its portfolio, senna would seem to focus on solid-state circuits though the published specs actually don't divulge the output devices. That would differentiate them from tube-based Trafomatic kit. Cosmetics and the red colour option meanwhile mirror it to give away the connection even if the website makes no mention. The apple doesn't fall far from the tree? Tubes or transistors? Check out the site and see whether you can answer that question. For the Onyx stereo amp shown, published facts are 45/75wpc 8/4Ω power, -1dB bandwidth of 5Hz – 250kHz, class AB operation and 6.5kg of weight. Bandwidth and weight suggest solid state, low-ish power for a transistor amp could mean tubes instead though output transformers should add more mass. Which way do you lean?
