That Nuwave looks a bit tastey!!!! You have to stop this Simon, you'll get me going. On that site, a black Dragonfly is £89 and a red one is £169. I can't see any differences excelt colour. Is red in this year? HaHa would not touch AQ with a barge pole.

Wow, they're not cheap!...will you take a kidney (or small child) in part-ex??? Are you just looking, fantisising or have you actually gone and bought one Simon?

Not trying to rain on your parade but.... for being a ESS based DAC the specs are a bit on the lowish side. It claims 0.01% THD+N (-80db) and a staggering 0.2% through 20-20K which is a couple of orders of magnitude worse than what say a ES9018 can do. Also flexibility is not up to the latest offerings being limited to 192K PCM and DSD128 DoP. Personally, I'd rather get the Teac 503 or, most probably, keep the iFi.

Personally, I'd rather get the Teac 503 or, most probably, keep the iFi. to be honest i have never really understood the specs. i assume , from what you say, thd is one of the most important. so out of all i have considered lately the chord 2qute is best in this area. its all the more confusing as some companies list the specs differently, as in thd on this for instance....... lake-people.de/produktdetails/DAC_V800.htmli dont have the knowledge to compare

THD+N is probably the most important as it considers both distortion (THD -> Total Haronic Distortion) and noise ( the +N part). To convert from % to dB and the other way round have a look here: THD to dB converter -112dB = 0.00025% which is a rather good number, it equals a 18bit resolution (ENOB -> Equivalent Number Of Bits where 1bit=6dB therefore 18x6=112). 16bit (CD) -> 96dB 18bit -> 112dB 20bit -> 120dB (practical limit for leading edge DACs) 24bit -> 144dB (no DAC has ever even got close to this number, max I've seen has been approx. 130dB and only noise not THD+N)

I'm sure there may be other factors involved than just THD+N. Mojo actually measures better than 2qute, and likely many other DACs, in that area.
Been meaning to ask. How are you finding the Violectric amp you bought? --
I'm not blown away by the benefits of DSD. Dynamics possibly are slightly better but like the Chesky material my feeling is that what matters most is recording quality and mastering. So I'm not going down that rabbit hole.
I've swapped from USB to optical on the Mojo and I think it sounds even better. It might lose a touch of air and treble 'detail' but I think over optical my music sounds a little fuller and more 'organic' (for want of a better word). Better isolated for PC use to I think so bit of a win-win.
What does puzzle me though is my cheap soundcard's (ASUS Xonar DGX) specs suggest it'll do a max of 96kHz over S/PIDF and when I play 44.1, 88.2 and 96kHz material the Mojo light correctly changes dependent on bitrate. With 192kHz material I assumed it would downscale to 96kHz but for some reason the Mojo indicates it's receiving 192kHz...any thoughts Javier? Possible I'm losing something in the process?
Thanks.
Edit: the first bit of my post was in response to Simon. You know far more than me so not trying to second guess you Javier! (started typing before you'd posted)

(started typing before you'd posted) i actually really like the v200, Mark. to my ears it sounds as "tube like" as i have heard ss. plenty of power and very quiet with the sensitive d2000. if i had to pick just one of my amps to keep, the Ember would just pip it. but only because i use Ember also as a pre for my speaker amp. the v200 cannot be used like this. i prefer the v200 and Ember over the micro hpa. i find the micro has a slight harshness in comparison, to my ears with my headphones.
