The sound quality from DACs - is it all the same?

The room the equipment is in and where the equipment is placed is IMHO even more of a factor than the equipment itself. ASR cannot determine, by testing one speaker of a pair, how music will sound on a pair of speakers in all users particular rooms. Thus for me, ASR is the ultimate in snake oil.  Worth a quick check before buying something but more worthy of a chuckle or two.

I prefer to not let myself be influenced by others confirmation and cognitive biases.

I don't consider gear a hobby. I consider achieving the best sound at an acceptable cost/benefit ratio a hobby. The gear itself is meaningless to me. In fact, the less gear, the better. My main source currently is Amazon Music HD via an Echo wirelessly straight into a preamp, so no CDs, LPs or hardware streamers.

Knowing how to read graphs, and understanding through measurements what is audible to the human ear and what is not allows me to "filter" gear before wasting my time with it. I don't consider it time well-spent to listen to something that measurements show obviously won't sound any different to my human ears.

The most straight out admission of confirmation bias I've yet read.

All the best,

🙄 Obviously. For those who think everything sounds the same.

Yup

I have an Echo feeding an older amp and speakers in the bunkie at our cottage. Dead silent surprisingly and there are no obvious artifacts.

@nonoise, to use the typical trope since you haven’t listened to it how would you know how it sounds? That works boh ways. I tried it after reading a review on some site that showed good performance. I was surprised.

no obvious artifacts

😂😂😂😂
