Well if you buy the DAC used and don’t overpay, you can always try and resell the loser. That's nice if you are really interested in hearing other DACs.
The weed, well it pretty much goes up in smoke and that's the end.. :^)
FWIW I’ve heard the EE DAC is pretty good but have not actually heard it.
I had an mhdt tube DAC. Tube rolling (coincidence) made a big difference in sound.
If you have a tube pre-amp and/or amp, I think little value in a tube DAC also. I sold mine and still use the SS version of the mhdt DAC and have been happy with that for several years now.
