today i got my new Focal Electra 1038BE ,help

i want to buy also the rest of the Electra system to enjoy also HT .

room is around 400 sqft
budget 5-8K
used /mint condition also an option for me

i'm from Houston , TX

what i need to buy? (maybe it's must for me to starch my budget in order to really drive my system property )

processor for HT , what model?
AMP:
stereo or multi?
i red that Pass Labs , Parasound Halo , Musical fidality , Simaudio , Classe , NAD M3 ,
specially Class A , are perfect math for them.

integrated:
i like the idea of using only one items to drive the speaker and save a lot of space in my living room
do you think it's a good idea to use it?

if i'm buying processor , i need also DAC ?

cables?

i watch most of my movies from my computer , also music
should i buy sound card?

i'm totally confused!

i got offer for PASS LABS , brand new for $6500
slightly over my budget
i'm sure this is an amazing AMP

any other AMP that cheaper and also can be consider?

Don't blow all your budget on an amp. As far as I can tell from what you told us, you need a lot of equipments to make these speakers sing well. Seriously share with us, how you came about to buying these speakers? It sounded to me that you wanted a multi channel HT set up / 2 channel music all-in-one system but you pretty much spent more than half of your budget on 2 speakers.

It's easier to set up for HT than finding good synergy gears for music, esp. for 1038 Be with its berillyum tweeter. These are very very good speakers and good speakers demand good gears.

For HT, getting a multi-channel AV receiver such as Anthem MRX (up to $2k) or Integra DTR (up to $2.5k) will do the job. But these AVRs and mediocre source (optical out from your PC) won't be able to do justice for music. But getting a good AVR is a good start as your system isn't dedicated for music only. AVR will allow you to watch movie and play music in one box.

Once you get your AVR and if/when you want more for music, your next step is getting a good amp. Pass has good synergy with Electra. If you have a small/ medium size room, you can start off with either Pass XA30.5 (used $3.5k) or X150.5. 1038 Be are 8ohm 93db efficiency speakers which means you don't need monster of an amp.

After that improve your source. Get a good universal player such as Oppo 95 ($1k) or 105 ($1.2k). You can do this before getting an amp too, AVR will work with CD player.

Next major step would be to get a pre-amp with HT bypass.

I know this is a lot of info in a very short amount of time. My suggestion to you is go to an audio store to seek help, explain your situation. And not just your around the corner Best Buy, you seriously need to talk to someone who knows these speakers well. (Someone who suggested these to you???) One thing I'm really curious though is how you even bought 1038 Be in the first place without experience and necessary equipments. Again these are top notch audiophile speakers and very careful system matching is needed.

this how i bought the Focal:
i started to find good speakers for around $2-3K
i red a lot of reviews online
then i remember that i had Focal sound in my car a few years ago and i loved them very much.
so i started to read review for focal.
i deiced i want 1028 BE and started to seek for good deal for them , then i was telling myself "why not to buy a speaker that i will do not replace for many years? even if i will move to a bigger house? then found 1038 BE brand new in sealed box for only $7100 (overseas , and i import them)

now i have a dream speakers in my living room that i never even listen to this model (or 1028)
maybe i'm so stupid , but i believe somehow that i chose the right speakers.
now i just need to dream to buy the Focal utopia someday.

now i think i need to focus on stereo and save money for HT

what do you think about integrated?
ModWright KWI 200 Integrated
or other brands

about DAC:
Wyred 4 Sound DAC-2 for example also can be use as PRE
second thing: if i will buy AV processor i still need PRE/DAC
i'm confusing about that also

for AMP i red that those can be good match with Focal:
Parasound Halo , Simaudio , Pass Lab , ModWright 100/150 , NAD M3 , Accuphase , Musical Fidelity Ams

there is more?
