I own the Yggdrasil Less Is More and upgraded from a very highly modified Cary DAC-100. The DAC-100 was very antiquated but with bypassing they’re buffer circuitry and coming directly off the Wavelength DAC board with a high end cable soldered directly to it and going into the tube input of my preamp sounded very rich and sweet. It just lacked the detail of newer DAC’s and I was looking to upgrade. I had tried the Cary DMC-700 which listed at $8500 but was only a small upgrade over the setup I had.
The Yggdrasil LIM (not +) sounded extremely thin but detailed at first. It kept sounding better as it burned in. I kept music from my custom server with JRiver playing 24/7. Two weeks in it started to smooth out and it wasn’t for about 3 weeks until I felt it was listenable. It was just so bright and thin sounding. A couple months in it sounded really great but would still probably not perform well on a very bright system. (So a couple of weeks with it is not enough time to really know what it sounds like). My system is very detailed all tube system with ET LFT-8b speakers and the panel tweeters don’t like brashy sources. I really like the Yggy LIM but you’ll have to make sure it’s right for your particular system. If your system is overly detailed it might not be a great choice. If you need to open up the sound then it could be perfect. It is a truly good sounding DAC with excellent sound stage and imaging. I like it better than the DMS-700 even if it isn’t as warm sounding. Also every time you unplug the Yggy LIM it takes most of the week to get back to its best sound quality.
