you can remove the mini tube tube adapter to run 6922 tubes in the tubador - this doubles your gain at the dac output... you can then tube roll and that is fun and good to manage tonality to your preference
good luck

Tubes used in the DAC are 5977 subminiature tubes. They are mounted on a special tube adaptor, which is plugged into a regular 9 pin tube socket. You can just unplug the adaptor and use regular 9pin tubes, which can be any of the following tubes: 6N1P, 6DJ8, ECC88, 6922 and 6H23P. After experimenting with many tubes we found that 5977 is the best sounding tube for this application. Second best sounding tube is 6N1P. After all it’s a matter of taste. All the 9pin tubes mentioned above have almost twice the gain of 5977, therefore you will have twice higher output level from the DAC - around 2V. Expected tube life for 5977 subminiature tubes is >5000 hrs.
good luck
