I did not detect such faults during my two extended sessions with the Utopia (and the $100,000 gold version). My conclusion in a nutshell was that, for my particular music genre (classical/opera), Utopia combines the best of HD800S (orchestral/choral) and K812 (vocal/chamber/opera) into one satisfying package.
I also auditioned the LCD-4 at the Questyle booth and was pretty underwhelmed (probably a bad idea to do so after having just auditioned the Utopia). I struggled to hear the difference between it and the LCD-3 (my favorite Audeze) but couldn't.
I listen to rock/prog rock/pop rock/ pop/folk and I experienced the same upper treble harshness on SOME albums as experienced by Currawong in his YouTube review of the Utopia's and mentioned by some owners on this forum. Not saying it's necessarily the HP's fault but owning 3 pairs of £2,000 - £3,500 HP's to accommodate different genres & recording styles is not what I want (on top of a reasonably significant main hi-fi system). When the Utopia's over revealing nature on 'some music' means you have to remember which music you listen to with which of your 3 TOTL HP's, I kinda feel a loss of enthusiasm. Others will no doubt relish the opportunity to swop TOTL HP's regularly, perhaps I'm being dull!
And as an owner for 2.5 years fo K812's, I am prepared to pay x 3 times for Utopia's but not if their qualities screw up 25% of my music. I'd rather keep the £3,500 and continue to live with my K812's which whilst not perfect, aren't a problem for my music listening. I collect my new Questyle QP2R DAP on Thursday or Friday morning (listened to at Friday's Indulgence Show in London) and it enhanced my K812's (over the too safe/soft Plenue 1). This morning I spent 2 hours listening to Pixie Geldof, Pumarosa, UB40, Susanne Sundfor (the new album, don't like her synth pop stuff), UB40 & The War On Drugs (new album is fantastic) using my MSI i7/3K laptop and a £165 DF Red + Jitterbug and it was a great experience. Looking to upgrade the DF Red and will be auditioning the Chord H2 and one or two others in the £1,500 - £2,000 for desktop study/laptop use but the Chord H2 is 11 x more expensive than the DF Red (diminishing returns features highly in hi-fi for sure).
But I will be borrowing the Utopia's for a 5 day midweek home audition and then I will decide whether I will be spending 3.5 x the cost of my K812's on another TOTL HP.
