This is probably the first of its kind in the world that uses discrete implementation to support DSD1024 and PCM1536k. The second edition to the highly successful original Holo Spring R2R Spring DAC. It is still my reference DAC use today.
"Another thing worth looking forward is its linux support. Since Spring 2 is the only DAC that supports USB DSD1024 at the moment. I hope LINUX will add its PID/VID soon for its native DSD1024 support. Currently, Spring 2 can only support linux DSD512 in a DOP fashion.
So for now, to experience USB DSD1024, windows system is the only way to go. But one can definitely use Spring 2 to try DSD512 on a linux platform."
Existing users will find this upgrade to be minimum. Specs wise are impressive but does one really need such a high sampling rates? The only thing I’ll find that may improve the SQ is the use of femto clock, some capacitors upgrades in the audio section (The two big caps) and the USB interface card which supports the newer XMOS chipset, but this can also be upgrade for the previous gen.
For new user, this is a steal coz the price difference for the older and newer gens are not too far apart.
I’m using the I2S input, which I see is still preferred for the Spring so the USB upgrade isn’t important to me.
I’m not sure what the Spring 1 would fetch on the used HiFi market in Australia, it’s a Level 2 with Jensen PSU capacitors, but doesn’t have the silver transformer or wiring.
The remote is more attractive than I thought, as the Spring now acts as a switching centre in my rig. It’s got inputs from the microRendu/Matrix Audio X-SPDIF 2 (l2S), a computer (Coax1), the TV (Coax2), a CD transport (AES) and a Chromecast Audio (Toslink). I change inputs to watch films so a remote would stop reduce the frequency of my daughters laughing at me - “Why do you use this thing with it’s big box Dad, it doesn’t even have a remote …”.
