It's a tough call between 3 and 4. There is a soft spot in my heart for the Sim, but the Audio Mirror DAC has been an excellent companion to my Alesis CDP which I am using as a transport. Option 4 will save you some money.
As a side note. I'm a big tube fan (amp, preamp, and phono stage). If you have not done so already I implore you to email or speak to Vlad at Audio Mirror as to why he did not build a tube DAC. If you don't have any other components that are tube based, a tube CDP like the Jolida with excellent NOS tubes can add a nice touch (I'm not a big fan of Shanling) to your system. However, a home audition with the Audio Mirror would be my first choice. If it doesn't work out send it back. You could also list it on Audiogon and sell it immediately for near cost. Heck I'm even considering buying another one.
Good luck with your decision. Really, other than the Shanling IMO you will be happy. Just happier with the Audio Mirror ;)
