Few weeks ago, I had the chance to visit KOtriode and listen to his system but more specifically his Preamp. The preamp use half of the 6C33C per channel (one 6C33C has two triodes). It has two outputs, one is transformer coupled output, the other is choke load (through transformer primary ) with capacitor output. The gain is about 8db, adequate for a preamp. The preamp has regulated DC supplies, uses only oil capacitor, no electrolytic. It also has a remote control, with 4 inputs, the pot is motorized Alps. The overall aesthetic presentation of this device is stunning but more important the sound is deeply involving with a great sense of openness in the full bandwidth. The first set-up was using the digital output of his tube Dac and bypassing the preamp. Though the intrinsic characteristic of naturalness was still here the sound was a bit more condensed and less seamless vs. using the preamp. In other words all the tiny glary aspect was gone yielding an effortless and highly compelling sound. I was much impress by the “humanistic” aspect of the sound bringing certain poetry to all the music that we listened. Anyway, I thought I will share this with you as it is only too rare to have the opportunity of hearing such a conclusive playback!
