"the T2+ amp—as though we needed any—is yet further proof that Sasa Cokic is an unusually resourceful gifted valve electronics man with a special mind for custom transformers. As an international if impromptu statement effort, T4+ as the combination of Serbian amp and Japanese headphone succeeds quite spectacularly with the small proviso that like any highly specialized effort," Srajan Ebaen, 6Moons
Sasa Cokic has designed, (being the transformer winding master that he is) a tube amp utilizing the EL 34 in SET mode...in (SET, not push pull...much more delineated and magical sound) It was specifically built to handle the tough load, i.e. very high impedance of the Take-T H2+ headphone. What is it like to get the Step Down transformer out of the way, and not to have to connect to another integrated amp? Well, it sounds remarkably better.
We had been using much more expensive amps to drive the Take-T, but right now, this Trafomatic design takes the cake...by a wide margin. It is an imperative, if you plan on the experiencing the Take-T. Together, they represent one of the finest, if not the finest headphone experience in Audio.
Output : EL 34 in triode mode SET.
Here's more review:
"The evening before I'd listened to my Aëdle VK1 off the RWA-modified Astell&Kern AK100 whilst on the exercise bike. It sounded like an echo chamber by comparison. T4+ stripped out all the fuzz, cobwebs and resonant blur for a view on the same scenery that was far clearer, cleaner and 'down to the bone'."
From that perspective, the H2+ as driven from the Serbian custom amp could well be the current best or most extreme.
Where "world's best" does enter in more meaningful ways...is the down-to-the-bone resolution. It unclogs the finest arteries which competitors seem to suffer by direct contrast for lazier blood flow." "for headfi freaks who already own numerous cans, the T4+ proposition is a can't miss because it goes places we've not quite been to before."
