Ok Pelo,
If I were you, this is what I'd do with $8k budget for electronics (opinions may vary).
I'd start off with a 2.0 HT/music all-in-one system first (then down the road, add center, surround, sub for 5.1 HT, but again my priority would be 2 channel music)
Amp - Pass + Focal Electra is a match made in heaven, especially XA.5 series. If you do not have a big room, XA30.5 ($3.5k used) should be enough for 1038 Be. I've heard nothing but good things about Parasound but I'm not familiar with them. What I do know is they run a few initial watts in class A and many people swear by Parasound.
Pre-amp - I'd love to recommend Pass XP-10 ($3.5-4k used) but this would blow your budget. Only consider this if you get a Pass amp. You could consider Parasound pre. It always makes sense to get same brand amp/pre-amp combo - easier to achieve tonal balance. Just make sure you get a HT by-pass with your pre for your HT duty.
AVR - Anthem MRX 500/700 or Arcam AVR (give or take $1.2-1.5k used) (I would not consider lesser AVR to pair with 1038 Be. But remember this is only for HT duty. I personally do not like playing music off AVR with Electra Be) Another reason I'd opt for AVR over processor is when you add center/surround, you can make use of AVR's internal amps and you probably won't need to buy additional amps.
Processor - I do not have much experience. But used Anthem Avm20 or Avm50 might be within your budget. Of course you only need either an AVR or a processor. Not both. With a processor, every time you add a new speaker, you'll need an amp.
DAC - $1-2k range would do the job. At the price point you have a lot you can consider. Most bang for the buck IMO is Metrum Octave NOS. Others - W4S DAC2, NAD M51.
Reclocker - I assume you're running music off PC through optical output. I'd like to recommend Empirical Audio Synchro-mesh reclocker ($600). You will place this between your PC and DAC. What this does is cleaning up your digital clock jitter. I personally use this and highly recommend this product.
I think the safer route for you is to go with Parasound amp/pre-amp combo. Talk to a Parasound dealer and I'm sure they'll have a matching combo for your budget (I just can't stop recommending Pass but they come with a hefty price tag). After that an Anthem AVR, a DAC, a reclocker and you're good to go. Good luck.
Oh wait, cables. Don't go buy expensive cables just yet. You can start off with cheaper models (anti-cables, morrow audio, etc). Getting right with the speaker/amp/pre-amp combo is the key. Then you can try out different cables for your preference. Cable co. is a good place to start after you get the amp/pre-amp/dac.
