I would get the Schiit preamp and amps, and call it a day. They will be, IMHO, the best-sounding, best performing (as in, plenty of current to drive your speakers) and...most reliable components you can buy at their price points. They will sound excellent, and...they come with a 5 year warranty. No one else offers a 5 year warranty on their gear. Plus, if you ever upgrade, you can easily sell them on to someone else. I just sold my Schiit Gungnir MB DAC yesterday, and it took all of a day to sell it.
