![]() ![]() Definition and Functions of an AmplifierĪn amplifier (also informally known as “amp”) is an electronic device or component that increases the power, voltage, or current of a signal. Finally, there are a few tips to help you get better sound from your audio system. In this article, we’ll address a few topics related to this question in more detail including, what an amplifier is and explaining its function, how an amplifier works, the types of amplifiers, and how various factors affect sound quality. Overall, the quality of sound depends on the type of amplifier, setup, external factors like room acoustics, among other factors. Amplifiers are fundamentally made to modulate volume, but they can also impact sound linearity and tone. So, are amplifiers one of the components that make the audio sound so appealing?Īn amplifier does improve sound quality in a number of ways. It’s extremely cheap maintenance: A refoaming kit will run you about $30 for most speakers, and capacitors are a couple dollars each.Quality sound is pleasing to the ears, and that’s why many devices incorporated into an audio system are aimed at producing great sound. Refoaming will be required less frequently. If you buy a pair and get the caps replaced, you’ll want to redo that every decade or two. Long-term maintenance is so simple it’s almost an afterthought. In a lot of cases, that’s just the old capacitors not doing their job and coloring the sound. It’s a common misconception that older speakers sound "warmer" than newer speakers. The capacitors that allow this to happen wear out over time, but they are easy to replace on most speakers. ![]() If you’re not sure how long it’s been, it’s also worth changing out the crossovers in the speakers-the component that tells the speaker at what frequency to start sending information to the tweeter instead of the woofer. There’s a reason companies like Klipsch and JBL still reissue these old designs regularly. Sure, they might not have the latest waveguide technology, but they still sound amazing. It's worth noting that there's no reason vintage speakers can't compete with modern counterparts. If you choose wisely, it will last a lifetime. Here are classic components that we audio nerds swear by, and a few tips on what to look for when buying old-school equipment. The best part? If you know what you’re looking for (and are willing to perform some maintenance about once per decade), your kids will get as much enjoyment out of their retro-futuristic trap music as you did out of Taylor Swift. If you know what you’re doing, you can buy an old amp and speakers that sounds as good as the latest and greatest options. Unlike TVs, computers, or other electronics, stereos that produce lifelike audio haven't changed too much in a few decades. I also agree with the philosophy of the movement buying well-made stuff that is repairable saves everyone money in the long run, and it means less junk in the landfill.Ĭooking eggs and keeping liquids hot for hours is great, but I'm most thankful for the human nerds who figured out how to accurately reproduce sound waves. As a reviewer of oft-frivolous things, I'm impressed by still-functioning, ancient items like cast iron pans, insulated thermoses, and hundred-year-old sewing machines. I frequently browse the r/buyitforlife subreddit. ![]()
