Tweedehands Versterker Kopen: What to Look Out For
Buying a second-hand amplifier can be a cost-effective way to get a quality sound system. However, it’s important to know what to look for to ensure you’re getting a reliable and good-sounding unit. Here’s a detailed guide on what to consider when purchasing a second-hand amplifier.
1. Check the Brand and Model
Start by researching the brand and model of the amplifier you’re interested in. Some brands are known for their durability and quality, while others may have a reputation for reliability. Look for reviews and ratings online to get an idea of the brand’s reputation.
| Brand | Model | Notable Features | Reliability |
|---|---|---|---|
| Marantz | PM8006 | High-quality sound, built-in phono stage | High |
| Denon | POA-800NE | 4K UHD video support, Dolby Atmos | High |
| Onkyo | TX-NR646 | AI Sound, 7.2 channel support | Medium |
2. Inspect the Physical Condition
When you find an amplifier that interests you, inspect it carefully for any signs of damage. Look for cracks in the casing, dents, or any other physical defects. These can indicate that the amplifier has been mishandled or dropped, which could affect its performance.
Check the power supply and output jacks for any signs of wear or damage. Make sure the buttons and switches are responsive and that there are no loose connections. If the amplifier has a display, ensure it’s functioning properly.
3. Test the Sound Quality
Before purchasing the amplifier, ask if you can test it with your own speakers or with a set of known good speakers. Listen for any distortions, hisses, or other unwanted noises. Pay attention to the clarity and depth of the sound, as well as the overall balance.
Test the amplifier at different volume levels to ensure it can handle high volumes without distortion. If possible, compare the sound quality of the second-hand amplifier with a new one to get a better sense of its performance.
4. Verify the Power Rating
The power rating of an amplifier is an important factor to consider. Make sure the amplifier can provide enough power to drive your speakers effectively. A general rule of thumb is to choose an amplifier with at least 50% more power than your speakers’ recommended power handling.
For example, if your speakers are rated at 100 watts, look for an amplifier that can deliver at least 150 watts. This will ensure that your speakers are not overdriven and that the amplifier can handle dynamic changes in volume.
5. Check the Connectivity Options
Consider the number and type of inputs and outputs the amplifier has. Make sure it has the necessary connections for your current setup, as well as any future upgrades you may have in mind.
Check for features like HDMI, optical, and coaxial inputs, as well as analog inputs like RCA and XLR. If you plan to use a turntable, ensure the amplifier has a built-in phono stage or a separate phono preamp.
6. Ask About the Warranty and Return Policy
Before making a purchase, ask the seller about the warranty and return policy. Some sellers may offer a limited warranty or a return period, which can provide peace of mind in case there are any issues with the amplifier after purchase.
Be sure to understand the terms and conditions of the warranty and return policy, including any limitations or exclusions. This will help you make an informed decision and protect your investment.
7. Compare Prices and Reviews
Once you’ve found a few amplifiers that meet your requirements, compare prices and reviews from different sellers. Look for the best deal, but don’t compromise on quality. Sometimes, a slightly higher price can be justified by the seller’s reputation or the condition of the amplifier.
