Hey Torq, have you heard of the R2R HoloAudio KitsuneTuned Edition Spring Dac: https://kitsunehifi.com/product/springdacgreen/? Seems to be getting stellar reviews vs. the Ygg with many selling their Ygg to grab the Spring. They are at the same price. The feedback is similar resolution, but the Spring makes the Ygg sound thin giving the Spring the musical edge - the Spring may have a little larger sound stage as well. This is what Kevin Gilmore who made the Blue Hawaii Amp had to say:
Kevin Gilmore quoted:
"The holo spring is the first fully compensated discrete R2R dac to come to market. The other discrete R2R units I am aware of (soekris,msb etc) do not do linearity compensation.
I think this is going to be a big deal going forward. At least until a monolithic R2R high resolution dac chip comes out. (could be a long time) It is possible, with 10nm technology, but not going to be cheap. Say $300 per channel..."

Tim has one that he is going to let me demo and you too if interested, but thought it would also be fun to do another group get together and see what the group consensus is on the Spring vs. the Ygg. It would also be a good excuse to hear your new Utopia as well to compare to the 4 and the Abyss.
Someone mentioned it in the "Life after Yggdrasil?" thread, but I didn't see a simple way to audition one. However, if Tim has access to it, then we should make it part of our next shoot-out session for sure. And make a day of it so we can get all four flagship headphones covered as well.
That'd also make it doable to add it to my all-up DAC evaluation (even if I'm really having to resist the lure of an extravagant upgrade to my turntable ...).
BTW, Josef bought one too so we have a couple in the group. We will have to start planning.
