R2R Dac choices.

I have a MHDT Labs Orchid and am very pleased with it. I'm sure there are a number of other good options.

99% of my music is CD based, either as disc or AIFF file. I am interested in both the Orchid and the Mirror Audio. I use a tube preamp however. 

Thanks everyone for your responses ideas and suggestions! Cool to have have a place like this where people will take the time to help follow music lovers! I'm still undecided but still leaning towards the Adagio. But the preamp scenario sounds good to me too lol. I guess I just need to make a choice and go from there.

I was considering the Hmdt, Audio Mirror and Border Patrol. The Border Patrol got punted first because of the single connection or high price to add a second one that was just switchable. The Hmdt looked interesting until I saw a review on the Pink Fish that at first raved about it then the user got obsessed about changing the chip and then later sold it off. Being overseas as well turned me off. The Audio Mirror DAC is based on the same chip Audio Note has stuck to for a long time and for a good reason. So the only question out there waa how good is Vlads implementation of this chip. With a 10 day return policy and being based on the US the decision became obvious. I'm just waiting for reports on the upgraded capacitors and comparisons. Very satisfied and buying lots more CDs because of it. Good luck!

Many good choices.
I love my Metrum Pavane. I do play it through a tube preamp - Concert Fidelity
