The generic power adapter may be above the industry std., but it barely meets the max spec requirement and is noisy to my tube amp. Your excellent Zen streamer deserves a better power adapter. It should be bundled with your excellent iPower. I am just pointing out your weakest link. This is customer input. What you do with it is your business decision.@KalahariLion thanks for the suggestions. The question of sub-standard is pretty relative and subjective. What I am referring to is that the power supply we offer with the Zen Stream is above the industry SMPS standard, so it it hard to state it is a sub-standard product. Obviously, you are right saying that iPower or other Silent Power products have the potential of taking the Zen Stream to the next level. If you then take an iPower as an industry standard (which is galaxies away from the standard), then our regular power supply could be considered sub-standard, but not in any other arrangement.
First few thousand of the Zen Streams were bundled with an extra iPower as as part of the promo deal, but it is not a part of a regular set.
