Hi Friends, I think I've outgrown my Forssell Dac for monitoring purpose. I found that I tend to cut too much low mid from it (too warm). I want a cleaner, more transparent dac. I picked those 3 above since they are available used in my area. I mix and master mostly on headphones. I use Neumann NDH20 for mixing and Audeze LCD4 for mastering. Which out of these 3 would you consider a monitoring dac (linear, transparent, revealing)? Thank you in advance for your advices.
