Thank you, everyone.
Erikminer, I know you had a Cullen PS Audio DLIII which you sold. You sold it to me. ;-) And you're right saying that if I don't buy the DAC2 and go for DAC1 I will always wonder whether I did the right thing or not.
The market has spoken. I got an offer for my MF I said "yes" to. I am a very rare breed, I guess, I sell first when I upgrade, to avoid/limit the tension with my wife which hates my hobby (probably me as well ;-) )
But "Long Live Audiogon". If using the DAC2 directly into my power amp will prove not to be the right thing, there will always be a preamp looking for a new home...
Again, thank you all for your input.
