Aumkar and I had a good time on Saturday. We started the day with a short city tour. I took him to visit the Temple of Emerald Buddha, Grand Palace, and Wat Poh. Then we had lunch with a few of my headphones lover friends. After that, we had a mini headphones meeting.
At the meeting, we had Stax SR007 MK1, SR009, My DIY Orpheus Clone, Omega Clone, JF Clone, and of course Aumkar's RR1 headphones. I brought my KGSSHV Carbon, KGST, and KG Grounded Grid, and my friend brought his DIY 300B single ended amp.
The RR1 showed very good performance with all the amps we tried. The treble was just right and the bass was impactful and deep. I think they're good headphones for fast music.
Aumkar kindly gave me a pair of RR1 and an extra pair of drivers for me to play with. Here are some pictures of the stators, spacers, and dust shield.
I'm very impressed to hear that he actually machines down the 4 mm aluminium sheet to 0.8 mm so that he can have the absolutely flat stators.
The look and feel of the headphones are good. Aumkar told me that all the cups are 3D printed, sanded, and painted in house. With all these labor intensive works, the result is quite impressive. I basically can't tell that these components are 3D printed at all.
All my Thai friends like his headphones and have already asked me to help place their orders with Aumkar.
