Well, there is some misunderstanding in the terminology here and I'm surprised that no one has pointed this out. The terms "Speakers" and "Loudspeakers" mean the same thing. The former is just a shortened form of the latter. And by "Home Theater" I'll assume that you are referring to the "all in one" systems also known as "Home Theater In a Box" (HTIB) and yes, these systems tend to be cheaply made and lack the performance that a good, high fidelity system needs to accurately reproduce music. However, there is no reason that a well designed home theater component system can't reproduce music just as well as anything else. If one is concerned that the multiple channels (5.1, 7.1, etc,.) distort the original intent of the recording one can simply set the receiver (integrated amplifier, preamplifier) to "Stereo" and use only the two front channels.
You should have stated several factors which would have allowed us to better answer your question. The aforementioned budget is perhaps the largest consideration. The size of the room and it's details (ceiling height, furnishings) are by no means unimportant. Your listening habits and choice of music also come into consideration.
I think what you are getting at is a set up composed of components rather than an all in one package. There are several different levels of component systems and each will progressively require a larger budget:
1. Receiver. Signal source (CD Player, Turntable, Tape, etc,.) Speakers.
2. Integrated Amplifier. Signal source (which in this example will include a Tuner). Speakers.
3. Preamplifier. Power Amplifier(s). Signal source. Speakers.
Within these three levels there can be permutations such as the addition of a powered subwoofer or a passive subwoofer with a power amplifier. One can also go the bi-amplified / tri-amplified route with several power amplifiers and an accompanying active crossover and the appropriate speakers to reproduce the different frequency ranges. I'm guessing that you don't want to get that complicated.
Therefore my recommendation is to go with the first level of component system and select the best components that will fit your budget. Others have mentioned several different brands of components and I agree that they are all of quality. I might add that Marantz, Yamaha and Pioneer (particularly their "Elite" series) make excellent receivers. Another important point is that you should audition the components if you possibly can. Any good, audio shop will have a listening room and allow you to bring your own music to test components. Read reviews and learn to understand technical specifications - distortion, power ratings, frequency response, power handling, etc,. Avoid brands that make exaggerated claims. If an inexpensive receiver claims to have 1,000 watts and weighs less than 30 Pounds (13 Kilograms) avoid it.
There is a lot of junk out there and a lot of advertising sneaky hype. An educated consumer will be able to sort it out.
