Another review on head-Fi.org, you can read here all about it. Quotes from different visitors of the Head-Fi meet in Chapel Hill NC:“The iQube was very impressive and a real winner for me. Its imaging astonished me and the sound was not boring neutral, but nothing was even close to overbearing. Nothing there to complain about, its sound was great, bass was tight, the amount of detail for its size was unheard of for me.” "The iQube, though, made my jaw DROP. Paired with my Monica 2, I was absolutely floored by the iQube, especially while playing a lossless copy of the Fellowship of the Ring soundtrack. I may be trying to get a hold of one of these (and a cable upgrade) when finances allow for another upgrade".
