DSD vs. PCM vs. MQA - Group listening experiment
The proof as always, is in the listening. If we can hear a difference in our system and with our ears, we choose the format that we enjoy. If not, we move on. Setting all theory aside, let’s just enjoy the music. This is the only fundamental that ...

DSD vs. PCM vs. MQA - Group listening experiment
We have done direct comparisons between DSD and 44.1-24/192. In my reference system, DSD was more holographic. The difference were not night and day but for me and my audio friends, we all preferred DSD when compared to all other formats. We did n...

Comments from Jeff Zhu :-".....I can’t say it’s 1 or 2 DACs inside. Physically, it is 1 DAC module, but it works in 2 different modes. Each mode uses different part of the module and also shared some parts. Spring is a 24bit DAC, bit23 is msb (m...

The Spring dac does not come with digital volume control and requires a preamp according to its designer. He must have very good reasons to not include a digital volume control.

Well, I can’t argue with Loesch. And I won’t argue with non-audio engineers too. :)

USB is horrible - you don’t want that. Asynchronous usb has come a long way to date.Even Thorsten Loesch of AMR/iFi fame, recommends usb over s/pdif despite his newly designed s/pdif Purifier :-http://www.digitalaudioreview.net/2016/05/ifi-audios-...

The Yamamoto YDA-01 dac at $2450 would be a better comparison with the Spring dac than the Bricasti SE at about 4 times the price of these 2 products.

Getting a bit confusing here, "discrete dsd" vs. native dsd........From Jeff Zhu, the dac designer :- "If Spring works in ’NOS’ mode. There is no oversampling, no conversion, just the original data doing the final digital to analog conversion........

as i know , AK4137 is only for SRC, it is bypass in the nos mode nos mode should be optimal for pcm as I have found with my own Esoteric dac(N-05 which uses the AK 4490 chip) set at no upsampling plus pcm filters off. Looks like for dsd, the Spri...

It uses the AK 4137 chip which is third in the "Velvet Sound" line-up of chips from AKM, used also in all Esoteric players and dac's. Interesting that the AK 4137 can be implemented as R2R.http://www.akm.com/akm/en/product/featured/velvetsound/htt...
