I know this topic has a dedicated thread on the Direcstream forum, but I wanted to share my impressions having just upgraded my Sprout’s USB cable today. After having really positive results upgrading my DirecStream’s USB cable with a Pangea solid silver USB cable for $99, I bought a second cable to connect my Sprout to my PC. The improvement in sound quality through the Sprout was just as impressive. Bass, detail, and soundstage have all been markedly improved. In addition the tone is much more natural and not as harsh sounding in the higher frequencies.
I found the improvement in sound quality to be well worth the cost. Highly recommended if you haven’t done this upgrade with your Sprout already!
If I had started my high-end audio journey with a Sprout, I wonder if my journey might not have happily stopped there for quite some time. It produces a remarkably satisfying sound out such a small footprint.
