Indonesia High End Audio Club or in short, IHEAC, held an blind test (or maybe I would prefer to call them as blind scoring) for tube pre-amp. The session was  started on the afternoon, around 11am. Some equipment used shown below.

We can see some stuff like Quadral Platinum M4 speaker, Consonance Droplet CD Player, Air Tight Reference Pre-Amp ATC-3, and KT88 tube amplifier (I believe in Push Pull configuration).

We’ll see between those two, who can serve the best supply for the DAC.

Coming soon…

Thinking about independent shunt regulator for each rail, precision passive I/V, and tube output.
