Answer
That is not the issue, there are good and bad PC speakers as well as home theater speakers, you either chose the wrong speakers OR you have them hooked up to the wrong amplifier, which also contributes to the sound quality.

So the key is buying speakers that sound good to your ears and in the room they will be played in as the acoustics of the room also plays a big role in the overall sound quality.

A very bright room (one with hard surfaces, tile floors, little furniture, no drapes etc,) can make speakers sound bright and thin and lack richness, and delicacy.

A room that is heavily damped can requires speakers that are little brighter to compensate for the absorption or high frequency's otherwise the system can sound dull and lifeless.

So the key is finding the right speakers for the rooms acoustics, and how you like to hear music, as we all hear differently. Simply listen to speakers with a wide range of music, so you can find the right speakers that sound good to your ears, and also keep in mind what the acoustics of your room might be.

What are the materials used in the room, and you can simply go into your room and listen to your own voice and clap your hands to see how live it is. Ideally when you clap your hands the sound should die off within 1.5 seconds. If you can still hear the sound well after that the room is pretty live. So you want to choose speakers at that point that are not to bright which can over exaggerate the brightness of the room, and vice versa if the room is heavily damped.

So once you choose speakers you like, then the next step is buying a amplifier that can both drive them properly and compliments them sonically.

You want to look at speakers efficiency and impedance.

For every 3db over its rated efficiency you want to double the amplifier power, till you get to the sound pressure levels your hoping to achieve, and then add a little extra so you have some reserve power and never get close to its maximum output. This assure that you don't over drive the amplifier ( the number one reason of damage to speakers or amplifier) sending a distorted signal to the speakers which can either damage the speakers or amplifier.

Then you want to buy a amplifier that compliments the sound of the speakers as everything in audio has a sonic signature. For example you wouldn't want to put a amplifier that might have a bright sound with speakers that also have a brighter sound, as you guest it your have a overly bright sounding system, and even more so if the room is highly reverberant.

How do you know the sound of speakers and equipment ? Well you can either read reviews from some the better magazines like Absolute Sound, or Stereophile, or try and find someone that knows the sound of equipment.

For example Marantz, Denon, (great brands by the way ) have a very sweet rich sound, almost like the sound of vacuum tubes. where as Yamaha and Sony (terrible products) have a very bright thin sound to them.

But even with that said its the combination of the speakers and amplifier to create a natural balance of sound.

Where can I find a PC headphone amplifier like this?

I need gain or volume boost and treble and bass controls. Don't need pro audio quality. I transcribe recorded spoken voice files, and sometimes the sound quality is bad. I used to have a pair of small speakers with a subwoofer, and I plugged my headphones into one of the speakers that had volume and treble and bass controls, but the speaker system broke. I'd like to maybe get a headphone amp that does the same thing rather than get a whole new speaker system (unless new speakers would be cheaper). Thanks.
Thanks for the recommendations, Andy. I'm okay with my headphones. The original source of what I transcribe is a phone, and some of what I transcribe is dictated on a cell phone in a car or maybe on a speaker phone 10 feet away or on a just plain crappy phone that sounds like there's a blanket over the phone. The quickest and easiest thing for me to do in these cases is just turn up the volume a little and roll off the bass and turn up the treble. I need quick and easy (and inexpensive).



Answer
If transcribing audio, although you don't have to invest hundreds of dollars, you probably need more than the $10 toys.

There is the cheaper and more expensive FiiO's and Beach is selling them at a decent price.
You also do need a decent set of headphones that are both comfortable and really clear on the mid-range sounds. I don't think treble and bass are key unless to turn them down.
You could add in a software audio equalizer.
I won't dig into them now, but browse through Nonags.com for freeware and see what you come up with.

As to headphones, you need to decide whether sound isolation is important. The open-back design sometimes does a lot better in the sound, but does leak out and in to neighboring people and environmental sounds.
Audio-Technica ATH-M50 Studio Monitor Headphones at about $160 - maximum isolation and ultimate comfort these rate amound the best at the under $200 in any review.
Sony MDR-V6 Monitor Series Headphones with CCAW Voice Coil at under $70 - probably too high on the bass, but these headphones make all sounds loud.
Creative Aurvana Live! at about $60 - build quality is not as good as others, and bass a bit weak, but the sound reproduction in the midrange seems to be right-on and price a value.
Grado Prestige Series SR80i at about $100 - Some find the pads uncomfortable and it leaks sound as an open-back, but the audio is full and crisp.

I think a lot of the sound quality will be in your headphone choice more than anything else, but laptops and even desktop pc's just don't have the best audio amplifying. In a desktop PC, you can invest in an over $60 sound card that would boost quality and you should look into reviews if that is where you are at. They often come with equalizer software.
