Please excuse me, I think I got confused by your earlier post. I thought you were referring to the issue of the complexity of balanced vs. the simplicity of single ended.
Often times a separate pre will offer stronger output to the amp, increasing dynamics and usually a separate pre will have a better, more suave volume pot, and as previously alluded to, balanced operation does have some inherent advantages. But if your volume controlled DAC is working well, the redundancy could compromise things. Your point is well taken.
