With Trafomatic Audio's Sasa Cokic going places as chief engineer for WLM's new valve audio line, one might assume that his own Trafomatic Audio line suffers now from lack of attention and ongoing innovation. Not so. Responding to a custom commission for monaural black/gold Experience Ones with upgraded tubes, Sasa just completed the above Experience One Reference monos. "They are similar to the Experience One integrated you reviewed but with a better power supply (double C-core main transformer), a separate heater transformer, an added EZ80 rectifier for the ECC81 supply and of course the Emission Labs 2A3. This really is the best tube. Unbelievable." Basic specifications include an output power of 4 watts, output impedance of 8 and 19 ohms (the latter customized for Avantgarde horns), input sensitivity of 1.5Vrms, THD of 0.4% @ 1W/1kHz; 2.0% @ 4W/1kHz, frequency bandwidth of 10Hz-60kHz ( -1dB | -3dB), S/N ratio of 82dB, input impedance of 100 kohm, power consumption of 150VA, dimensions of 390 x 260 x 160mm and weight of 14kg. Though a smaller outfit as chronicled in our RoadTour Serbia chapter, Trafomatic is wonderfully adaptive when it comes to pleasing their customers.
