Need help choosing my first amp for my first speakers


Hi, I am completely new to this world of hi-fi audio and I would like some help from the collective intelligence. Please bear with me even if I sound like someone who has no idea because I am.

I have just purchased my first set of speakers. I bought a used Boenicke W5 SE+. And I am looking for an amp to go with it. The speakers were a good deal but still not cheap and Im already mostly hitting my budget limit. 

I don't have any gear right now (I really mean 0), so my initial thought was to buy a Wiim amp to start off and then start changing to a more serious amp later on. (I like that it has everything including a streamer for me to get going right away)

So my questions are 
1. will the Wiim amp be able to power Boenicke W5 SE+?

2. What do you think of the plan to start with all integrated cheap amp and then changing later?

2. Any other amp suggestions for the speakers in a similar price range?($500 ish)

3. Can I just get Audio cables from Amazon?

4. How do you calculate wattage for the speakers from the speaker specs below?

5. Any other tips for a complete beginner would be appreciated.

Thank you so much for your detailed response @soix. Really helps me a lot! One question, is there a reason why you are calculating for 8 ohms when the spec is Nom. impedance: 4 ohms? And would the calculation be that the amp needs to supply 200 watts per channel at 4 ohms (This speaker)?

Thank you all for your kind expertise on this matter. I am glad that I asked here so that I don't do anything to damage the speakers (I would rather wait then to damage them). I will look into all of the options posted in the thread.

I will listen 90% from streaming and 10% from LP. My room size is 16’ x 10’ - and one of the 10’ walls is an open side to the kitchen for another 10’ x 12'. I will not be blasting music, since I have neighbors in my apartment building.

One question I have for amplifier powers is that some provide the same wattage for both 4 and 8 ohms, for example, NAD C 3050's power says

  • 100 watts x 2 channels into 8 or 4 ohms (20-20,000 Hz) at 0.03% THD

Would anything like this not work on my speakers because it is only 100w for 4 ohms? This is over my budget, but I still want to understand and learn.

As per the username, it came from a place of frustration when everything I tried was already taken (a generic name I have), so I just typed my initial 12 times. Nothing religious or meaningful. But someone did comment on this thread earlier about it not being serious enough for people to comment on my questions, but you all did and I appreciate y'all looking past the 24 letters of my username:)

I am glad I asked here, so many good opinions. Thank you all for the advice, think I understand much better than before. going to go through the book and deep dive one at a time. y'all are heroes. Thanks a lot!

Hi forum friends,

First of all, thank you very much for all the advice, it really helped me a lot to choose my first amp. After consideration and more research along with trips to nearby hi-fi stores, I decided to combine my subwoofer and amp budget and choose the one that would fit right with the speakers with enough power for me not to want to change the amp for a while. I went with a used Rotel RA-1592MKII amp at a really good price. Being a beginner, I was really worried about damaging the speakers and I have peace of mind with this wattage. Having speakers boxed and waiting for choosing and finding the amp was quite hard but now with everything I am very content with the choices I made. I've been listening to music more attentively and playing genres that I rarely listened to before. It brought me back to my young days when I had fun 'discovering' new music. As per the sound, to my ears this setup works better with natural instruments, strings, vocals, rather than something that was created digitally, hip hop, electronic and etc. The sounds feel full-er with instruments and computer-generated sounds sound a bit empty. Also, I think I could use a subwoofer for more bass, but that's for later(I still enjoy most music without it, but for movies and electronic music, I think it could benefit from it). I connected a wiim mini and use this speaker for everything, (music, tv and movies.) The amp (Rotel RA-1592MKII) was very heavy but looks nice and is easy to use (though the remote... looks like it's from the 90s). This is my first setup so I don't have anything to compare it to, but I am happy with the sound that I am getting. Again thank you all for all the advice and comments, you guys helped tremendously.

Happy listening!
