I have been feeding my dragonfly DAC into the Pan Am. That way, I can do quick A/B tests by simply unplugging the 1/8 inch and plugging in my IEMs into the dragonfly. I did also try AB testing between the Pan Am DAC and the Dragonfly. In both instances, the Pan Am has little or no impact in the bass, while the dragonfly punches substantially. The difference is dramatic. The Pan Am sounds nice across the spectrum, but very weak in the bass. I allowed the Telefunken tubes to burn in for around 20 hours before doing the A/B tests. The stock tubes have had little or no burn in, but with both tubes, the bass is quite disappointing.
