there's one in the FS forum for sale...thinking about it. been wanting to listen to a good implementation of the 1704UK chip...i imagine it'll mate well with my hd800 and th900?
only concern is i'm set on using USB out from my computer and i hear that the 10.32's USB implementation isn't very good. problem or not?
l have used both SPDI/F and USB inputs. Currently, l am on USB. l do not notice any difference between both inputs. However, l admit l haven't done an exhaustive A/B comparison but, the little one l did revealed USB input sounding a bit louder than SPDI/F.
Now, USB used to cause BSOD on my PC (that's why l swope to SPDI/F). However, wanting to fix the problem, all l had to do was to plug the USB cable on a USB 3.0 port of my PC (instead of 2.0, obviously). l have never again had a BSOD. l don't know if what made sorted the problem was simply 'swapping USB ports' or 'using a 3.0 port'.
When l used the SPDI/F input, it was via the sound card Asus Xonar Phoebus.
....
l have no experience listening to any of those HPs you mentioned. l am tempted to buy the HD-800 but, at the moment, l am trying to get familiar with my HD-700 before l buy the other ones. So far, l am truly enjoying the 700s (balanced). ln any case, if you 'search the thread' you'll see how many people love the pairing between the Reference 10.32 and the HD-800s. Even Mr. Kingwa, when l asked about a HP recommendation, suggested the HD-800. As far as l know, you would want to use the 'balanced out', instead of the SE.
l don't have great experience with other DAC/amps (other than my Fiio X3, sound card or a Maverick Audio 'combo' l had in the past) but, l can't be happier with this unit. The more a develop my listening skill, the more l appreciate this great device.
Hope you manage to get it! Best of luck!
