Your amp and speakers are your weak link for now.I personally beleive in putting most of your budget on Source and speakers.The beginning and the end. As time goes by upgrade the pre. and then the amp, and last but not least the power cords and ICs and speaker cable.I would for now, and this is my opinion, get some speakers, get some around 90 db at 1 watt and has a steady inpedance. May I recommend Living Voice,Buggtussel, V. Schweikert 3.5's, or Silverline Corona.Build your system to be neutral, then you can flavor later with having two or more amps around to throw in, depending on your mood. Because there are a lot of good sounds from different manufacturers and one can never have all in one system that does it all perfectly.
