@Atriya Do you live near any of the CanJam or other audio show locations? I'd recommend that you take your Utopia to a show and try it on different amps. For instance, both Ampsandsound and LTA tend to attend all the major shows. Even if the vendor is a headphone manufacturer, they'll normally let you try your own headphones on their gear to compare to their headphones, so you can use that as an opportunity try one of the amps they are using.
Reviews are useful, but at the end of the day, they're just opinions, to be used as data points. I happen to trust that particular reviewer from the linked review, because he's thorough in his testing, very detailed in his write-ups and also consistent. On the other hand, he and I have different preferences in sound and in music, so I tend to gravitate to different gear than him, but his reviews help me determine if I'm going to like what he likes.
This is very good advice. I'm not that far from Dallas (CanJam Dallas in a week). It looks like ampsandsound won't be there, but LTA will be.
