Can you comment further on the poor performance on the DAC side of the equation? is this something the firmware could address? getting significantly below chip spec of 93db SINAD

Last I read on the topic was that miniDSP was supposedly trying to source some testing equipment for their analyzer so they could repeat ASR's tests. Haven't seen anything since that.

seems like they just make products, but then don't support them?

6 posts on the forum with 5 of them in this thread, thank you for your outstanding contributions to the community.

Not sure what performance you expected when miniDSP advertised THD (not THD+N) at 0.006% (-84 dB), eyeballing the ASR measurements performance seems pretty close to that. This DAC was never going to be world beater and was never advertised as such.

ha, yikes, hope feeling superior to people online validates you in a way life clearly cannot

i posed a question for something clearly none of us at home can measure. it even appears miniDSP doesnt even have the equipment to reproduce based on another comment (dependent on his comment being actually true). so why am i being chastised to ask a company to stand by a spec they clearly missed (15db off the chip spec) and 6db off what was measured by an independent measurement vs what they advertised. what if miniDSP found a bug or error that was easily remedied and we all win?

and it might have occurred to you, that this is the only product of theirs i own, why would i be a contributor, to a forum for products i dont own? ease up buddy, it's just a question, and it's take 8mo to even get your response, let alone anyone from miniDSP to even acknowledge (which they still havent). people come here for support from minidsp, and potentially the community. this IS going to be filled with criticism and challenge from the people who spent their money on these products

Speak for yourself about not being able to make measurements, pretty trivial to do (especially at this level of performance) with less than $200 of equipment. See attached for my measurements of an OpenDRC-DA8 (which uses the same miniDAC8 as the UDAC8). Pretty darn similar to ASR and certainly not a surprise to me based on the published specifications from miniDSP.

 

Do you understand the difference between THD and THD+N? miniDSP did not specify THD+N so I do not see how you can say they missed their own spec by 6 dB, the ASR measurements exactly match the miniDSP spec for THD. Chip spec does NOT equal miniDSP spec, this is clear, not to mention that 93 dB is typical chip spec, min chip spec is 84 dB.

I am sorry if this comes off as rude but I have little patience for people that complain about measurements when they clearly do not understand them. Especially when they match what the manufacturer provides. If you bought a UDAC8 expecting different performance that is 100% on you for not being able to understand the miniDSP specifications.
