Well, here'e another response. I spent most of my money on speakers ($3600), then on TWO ARC amps ($4500 due to ebay) and lastly, the DAC and Digital X-over. My source is a PC, or a receiver, or one of two CD-Players. The system is Bi-amped, so the use of an integrated amp is not an option. Total price I can't recall, because my best CD-player is a Phillips, which I purchased long ago. Don't be afraid of the DACS making your sound too harsh or two-dimensional, the tube amps can smooth things out considerably. Just a thought.
