Polyglot, thanks; I'm glad the article helped.
I can't speak personally to the efficacy of upgrading the output caps, but I do believe that it likely would benefit the unit. There are others far more knoweldgeable than me in that regard and if that is your determination I defer to their expertise.
OTOH, I don't know what it would set you back cost-wise to do that upgrade if someone else did the work. I believe that you would achieve a larger return sonically to simply move to the DAC Plus version, as there are significant design improvements such as the elimination of the volume control, and separate transformers for the SS/Tube output. The difference/improvement is not subtle at all, and the benefit of rolling discrete Opamps is only amplified (pun!).
