From ifi Audio. It filters out electrical noise coming from the computer in my case. Amazon sells it. So does B & H.Sorry that I don't know but what is an iPurifier?

Thanks for your impression. Helps us build a picture.
I used both iSilencer and the iPurifier3 and noticed a fairly significant improvement with my COBALT when I used it as a desktop system out of my computer. I noticed more relaxed sound with better spatial and soundstaging cues.
[SIZE=14px]@Condocondor[/SIZE], have you tried it with your HD 6XX yet? Or has anybody tried the DFC with higher impedance Sennheisers or Beyerdynamics? Especially the HD 650 or DT 1990? I always found the DFR to be loud enough, but not quite resolving enough, or something.
The DFC has the same amp specs so if you were happy with the way it drove HD6xx then you'll be fine. The HD6xx was not resolving enough for me...it wasn't the DFR which I tried them with. I sold my pair off several months ago. Need to update my profile.
Well, I wasn't quite happy. Like I said, it got loud enough, but something was just missing. Sorry to be so vague, it's been a while and the DFR is currently out of commission, so I can't really revisit it. I was mostly wondering if it was a power issue, or something different. If it's power, then the DFC will likely be the same; if it's something else, there's a chance the DFC would be better.The DFC has the same amp specs so if you were happy with the way it drove HD6xx then you'll be fine.

Anyway, thanks for your reply.
Thanks for your impression. I haven't heard any of the DF's but I'm very interested in the Cobalt to use on the go with Tidal out of my iPhone. I was leaning towards an IFi Nano B/L as I am generally a fan of the Burr Brown sound, if there is such a thing, but having something with no battery to manage would be very welcome. I had a Mojo for 18 months and sold it but don't miss it - technically a powerhouse and a marvel of detail retrieval but perhaps lacking a little vibe for me. John Darko talks about DFC being more relaxed- sounding than Mojo which appeals.At about 75 hrs of run in i've been listening pretty intensively to the DF cobalt for a day or so now. For the record im a believer when it comes to burn in with pretty much every component involved in sound reproduction, but the amount of time required and the amount of change in the sound does vary drastically. Now either the DFC hasnt burned in at all, or it falls into the camp of not much change, because i cant hear a massive amount of difference compared to when it was fresh out of the box. There maybe a bit more extension and control in the low end plus the mids sound a bit more fluid, but these are definitely not what i'd call night and day differences. By comparison i've been burning in a Neotech UPOCC silver HP cable i made last week which after 150 hours sounds like a different cable (sorry i couldnt help myself pulling the pin out of the cable/snake oil hand grenade with this comment ), with lovely deep bass and full bodied mids, where neither existed before.
Anyway with the fire light, i'll quickly scurry back on topic. I've been listening to mainly electronic music, with the DFC plugged in to both my iphone and mac with Focal stellias on the other end. I have also spent a good few hours A-Bing with my trusty and much loved DF red. First off they're tuning sounds slightly different to my ears. The red, to my ears, is slightly warmer/ fuller and maybe a tad more organic sounding, whereas the cobalt is closer to neutral with cleaner airier more uncluttered presentation. Theres definitely more width with extension at both end and the improvement in seperation is instantly noticeable. across the whole range. The sound is a bit more dynamic and weighty but maybe lacks some of the organic charm that has made the red+iphoneX the go to (or repeatedly come back to) combo over any of the DAPs i've dabbled with over the last 18 months or so. Despite all this and now having spent a bit of time with the cobalt, going back to the red it sadly sounds muddy, congested and a bit noisy.
The low noise floe and reduction in RFI is something worth dwelling as i speculate this might be one of the biggest contributing factors to the Cobalts overall performance. The red is noticeably improved with the addition of spattering jitterbugs (especially noticeable with my mac as the source but then again the listening environment is generally quieter and more conducive to noticing such things), whereas the cobalt seems much quieter and having tried various combinations the jitterbugs, they seem to have little or negligible effect. Even with the iphone i'm hearing much more of the music, lots more micro details and room between the instruments, even at pretty moderate volume levels.
Is it worth £100 more? well to me yes because after 25 years of 2 channel listening i've come to terms with diminishing returns and in this the function of the cobalt is as good as its form is useful, and i'm not so tempted to pack my Hugo2 when i head off another work trip tomorrow plus the nagging um'ing and ah'ing in the back of my head as to whether of not to buy another Mojo has been put firmly to bed (i prefer the presentation of the DFC and i dont need the added power). I should caveat the H2 statement with a disclaimer that there maybe a tiny bit of new-toy syndrome going on here, but i can let you know when i get back if it was missed or not!

Let us know if you perceive any further changes in presentation with more hours on the clock.
Definitely. Small is the new big.Don't disregard the form factor of the Dragonfly. I never ended up actually using external DACs with my iphone because I had to keep them charged or they were just too clunky in my pocket. I actually use my dragonfly red because of how small it is.
