Good insights.
Kren0006, since the Edge W and Edge A share the same amplification stage, the only difference in both would be the DAC section. The current Denafrips DAC is quite the performer , judging not just by positive reviews but personal experience with it has been one of the reasons to dip my toes in the audiophile world.
Now, I do plan to hang onto streaming directly over my pc to the DAC/Int Amp, the addition of the volume control on the Edge A was practical advantages over limited control over volume from the pc, which can be slow and inaccurate for the most part.
Either way, the SQ of the amplification stage in both configurations is what is most important. Paying a bit extra for the volume control and remote functions for pure convenience purposes in the future may be worth the extra investment.
