I cannot say the DAC Plus sounds close to a modded MiniMax DAC. I have yet to hear one.
After RMAF, I might get a chance to compare the two.
Bill has asked me to not offer mods. For the time being, I have decided to honor his request.
If you feel strongly that what is done to your unit is your business, as long as you realize any work on a unit will void the warranty and you will have no recourse to a manufacturer, feel free to PM me or E-mail me.
I am also exploring another path in regards to a DAC. It will be a far more expensive item, but the sonics should be amazing. This might take another year to come to realization.
