I bought both Monoprice Cavalli units the Liquid Spark and Liquid Platinum, they both sound wonderful that "Cavalli" sound is very addictive!
Sadly after a couple of days, I started to have multiple problems with the Liquid Spark intermittently I have sometime mono sound, some noise/static with some files, and the unit just goes off and back on a few time. I have returned the unit to Amazon and I hope the new one will be trouble free.
As for the Platinum, I just experienced sparks when I connected the power adapter to the unit I sincerely hope this is nothing
I going to read more about this on Head-fi forum and see if there cause for concern.
So far the sound of both units is fabulous but the manufacturing from Monoprice might be a problem, we shall see.
