Hi Liam.
Now i can hear better i can perhaps give you some info.
You will have to contact Peter Daniel on the Audiosector website for pricing. As far as the sound i am pleased with what it does. It has very good bass and it does not suffer from the mushy sound as some people say nos dacs have, in fact i have had to turn bass and treble down a little. Volume also needs to be watched as for some reason it has a higher noise floor, don't know why, perhaps better dynamics. When i first tried the dac it hardly had any bass but a few hours on it improved considerably. It uses Blackgates and Rubycons and i have read Blackgates take an age to come to their best. Voices have more clarity and instruments seem to have a more solidity to them. There is no change to the sound signature as such, but an improvement to dynamics. I have tried to explain the best i can and hope this helps Liam, but i don't wish any backlash to my findings as Liam as asked me for them.
It doesn't come in a case just made up on the board. You can have some rca sockets fitted for extra if you don't want to connect it direct to a transport. It can be bought in diy form so its up to you what you are capable of. I would also ask him about feet to go under the dac as in bar bones i was concerned about the circuit laying on the shelf without any air under. I just used some computer spacers, the ones to fix motherboards to the case.
Hope this helps Jim.
