Welcome, Bojan! I've never been to Serbia, but I do know that you're very lucky Serbia has a vibrant scene for homegrown hifi that has spread worldwide, from Dayens, Trafomatic, Vista and Solaja to RAAL. I only know this because I used to own a Serbian amplifier: the Dayens Ampino, and the Serbian family that run it are rightfully proud of each amplifier they build. I look back on the amplifier very fondly.
