UPDATE: Having been to the London Indulgence Show last Friday, I collected my new Questyle QP2R DAP from Audio Sanctuary (who organise this London Hi-Fi Show). Whilst at the shop,I auditioned the Hugo 2 with my K812's and knew it was fabulous within 15 minutes of listening to wav music on my laptop. I had been warned I might find the K812/Hugo 2 too bright but I thought the sound was amazing and obviously a huge step up from my DF Red (and so it should be when £165 goes against £1,800). I loved the bass, quality & quanity, the open & clean midrange and the Hugo 2 gave me that little bit more treble from my K812's (exactly what I was after). So I gave Audio Sanctuary a deposit for a black one and they say that the next batch arrive in 4/5 weeks, can't wait. Apparently 4/5 weeks does mean 4/5 weeks (I refer to the stretched delivery times which frustrated a number of people understandably). So I would like to thank everyone who has offered advice and help, both here and via PM's re two of my upgrades.
When my Hugo 2 is run in, I will then borrow a dem pair of Utopia's and see how they get on with the Hugo 2, like them with the Questyle QP2R DAP at the Show but whether they represent +£2,000 worth of value to me over the K812's is to be seen!
