Valab TDA1543 DAC VS MHDT Havana DAC


I currently own a Havana, I'm just curious as both Valad and Havana are NOS DAC, as far as some user reviews go, some regard valab highly but none was compared to Havana.

Don't get me wrong, I'm keeping my Havana, but interested in Valab as well, to me they "seem" to have similiar sound, so any thought on that will be great!
Thanks

I don't have the Havana. I just want to say, as a long time soldier for NOS, I am tickled to see the popularity of NOS grow as time goes by. Walk up all the way with the cool sound of NOS.
Karmatogdral,
Could you explain the difference in sound between the two tubes? I have been loving the WE396a but would like more soundstage in my system. Does the tungsol still have that amazing midrange?

Thanks,

Greg
