I had a DAC-2v2 SE DAC for a number of years and it's a very nice sounding DAC which you can pick up used at a very reasonable price.
I thought I was upgrading when I bought a HOLO Springs 3 KTE DAC, but I was mistaken. The HOLO had a quirk that drove me absolutely nuts - I couldn't take it after six months. I decided to step clear of all the flavor of the month DACS which are so frequently reviewed and bought a Aries Cerat Helene DAC.
It wasn't cheap, but I'm now content in the world of DACs
