Many power and signal parts in Bakoon amp are replaced with better ones. And I put my Wavetouch Power Cords (WTPC) to internal power lines of Bakoon and Oppo. The clean and powerful electricity pulls the sound much closer to me. I mean after the mod, the sound became more forward and intimate like a real live music.
Also, the sound became more organic. When I hear my system (WT22) I can hear/feel moisture of lips and tongue of a singer. And there are warmth of sounds.
There is no strain on my ears since the sound is pure. I can listen it forever. And I can hear all important musical detail and emotions in low volume too.
WT22 is loud for large rooms too. My shop is 44'L x 32'w x 12'h and the sound is loud. Bakoon is 35watts.
