A while ago we had visitors from Holland. Their car were loaded with their own electronics.

Hand built tube amplifiers from Impact Audio.

CD-player with seperate DAC. Power bank/cleaning that wheighed 60 Kg. They had to build a small carriage to move it around.

They mostly listened to classical music, but also some jazz and blues.

We moved around the speakers to get the most optimized position, before the listening. In the end they were placed far from the walls, and we raised them around 10cm to get the most "air" out of the tweeters.

After 4 hours of listening the XTZ 99.36 MKII was chosen to bring home.
