Maybe you don't have to measure the bluetooth part of the performance, since most bluetooth dacs also have standard desktop connectivity and most of us want to use them primarily as desktop plugged DACs and sporadically test bluetooth headphones with them. My vote for DAC to review would be the...
I would definitely love to read your review of the SMSL DP3 DAC. It's very interesting, it's almost the only packaging Bluetooth and balanced outputs together (maybe even ultimate DAC to buy for only $250 if it delivers good performance?)
The Sanskrit 6th has less jitter and lower noise floor than the Modi 2 Uber https://audiosciencereview.com/forum/index.php?threads/bargain-dac-review-s-m-s-l-mini-dac-sanskritt-6th.1728/
Unless they are somehow not comparable?
I agree with @tili, there are people who need to pair their Fiio E10K, OL DAC, Topping D30 budget dacs with any good budget amp to spend the rest on headphones. So, there will be a huge impact if discovering a good budget amp in your reviews.
From the ones that you've measured
Schiit Modi 2
JDS Labs OL DAC
Other:
Schiit Bifrost (not the multibit)
A DAC that you have bought I think:
SMSL m8a
And it's also in the SMSL Sanskrit Pro-B.
I would certainly prefer the Pro-Ject Pre Box S2 DAC to the Topping DX7, but I always make a huge differentiation point the size of the boxes they are in (preferring smaller boxes). And I think I wouldn't want to use the Topping integrated AMP with most of my headphones (85% of them below 70ohm...
Well, it's a conversation going on, something that would be impossible on HeadFi because you would be banned from posting in the thread after mentioning measurements, competitors' products, subjectively preferring other products, the validity of the subjective assessment of sound, linking to...
By the way, why would it have any merit a warm-up period argument? Most electronics perform their best at lower temperatures and go up the scale degrading their performance slowly when they become hot. Is there something I ignore that make it different for DACs?
Well, now that results are posted you know for sure that you could still sell your 'optimal and bug-free' code at a higher price range. Just make sure to claim that it is their fault in using the lower-end code in a wrong way by expecting the best results before several days worth of warm-up period.
I wouldn't suggest that leaving a 35W device turned on all the time is an acceptable engineering/design compromise, so I am consistently turning off both my DACs and my TVs. You are not, so you need to justify what makes it different for DACs than it is for TVs.
Hey, you have already changed the goal post. What makes it ok to leave a DAC on all the time but makes it necessary turning on and off a TV? Imagine the TVs image was superb after a 3-day warmup. Why wouldn't you leave it on? Most LED TVs nowadays use 45 Watt or less when turned on. The Power...
