You can never go wrong with Pass , it's to bad your budget doesn't permit a Pass amp but Bryston is very we'll made and respected check the Bryston forum on Audio Circle. You are correct about wanting good power from an amp. I see nothing wrong with these two pieces as starting points. I agree with going the used route you will get much more for your money. I think you will be happier spending a bit more than the Schiit on a phono pre, there are lots of great ideas on this and other audio forums. There are many different opinions on cable, fuses, power cords, interconnects and speaker elevators study them carefully before investing. As for speakers there are also multiple options available you just need to research then get out there and listen and find the sound that turns you on.
