Amp recommendation and setup advice please

Hello,

I love music and I adore quality sound - I cannot listen to music on ordinary speakers/devices.

I have been trying to do my research on sound systems/speakers/amps etc.. and learn/understand the whole shebang, but I'm not that much of a tech head. 

I want to buy the Klipsch RF-7 II tower speakers (I think they are passive, hence requiring an amp). 

I want them for both my new TV and also the vinyl/turntable setup I am going for, which is as follows:

Turntable - ProJect Debut Carbon Premium with Ortofon 2M RED (cartridge)
Phono (pre-amp) - ProJect Phono Box DS
Speakers - as above
Subwoofer - thinking either Klipsch R-12SW or R112SW
Amp - ??

I have a few questions:

1. Am I on the right tracks for having all the essentials?
2. Can someone recommend a good amp to power my speakers and sub please, and does the sub need powering or does it have it's own amp? 
3. Do I need a DAC for TV and connection to laptop? If so can you recommend a good one please? I was thinking of Audioengine D1 Premium 24 bit DAC Interface Connector.
4. Please suggest any alternative products if any of the stuff I mentioned are no good or don't fit together that well.
5. How would I set all of this up? Do I need anything else?
6. Do I need more speakers? I'm worried that the sub may be too much bass and drown out the tower speakers. 

I apologise for my lack of knowledge - I've just signed up here because I read that I could get advice and guidance from enthusiasts and experts. I know that my questions and post may frustrate some of you as I may have made some rookie mistakes, and perhaps this type of post has been done a 100 or so times but wasn't sure how to get answers/help. 

Many kind thanks in advance!

No, it would not work.

Please re-read this entire thread very carefully.  We have already covered the ideas of an HT Receiver or HT Processor.  This is what you would need for HDMI stuff.  During our discussions, the direction went towards a high-end 2-channel DAC.

You might be able to use an audio output from the TV. The NFB has one set of RCA analog stereo inputs (IN5). You might have to get a special cable.  It would not be as good as digital input, because you would be using the DAC in the TV, but it would probably work.

Essentially, a preamp is used for several things:

- As a way to switch between multiple sound sources (i.e. CD player, tape, etc.)

- Be able to provide a way to adjust volume

- Contains a circuit that has enough current to drive certain amps (sometimes digital sources do not have enough current in the analog output circuits).

You missed one- the line stage is also used to reduce or eliminate the effects of the interconnect cable. This is probably the least understood function of the line stage.

Ralph, re: your comment about eliminating or minimizing the effect of interconnect, could you please elaborate? I own an ARC Ref6 and ARC Ref150se and I keep getting advice from certain dealers that I should upgrade my IC between the two. I will say this; I have four XLR IC's at my disposal at unless it's in my head, they do sound different! Does this mean my Ref6 is not good at it's job? My question is posed with nothing but earnest sincerity.

@auxinput I have everything up and running now but I’m not entirely convinced of the sounds. Perhaps I have set it all up incorrectly or maybe I need to do something with the settings of the TV or Satellite?

I feel like I need a subwoofer as the bass isn’t enough, and I also feel like there isn’t enough clarity in the highs (possibly the mids). 

Any thoughts/recommendations please?
