You need to consider the speakers you’ll be using before you start looking for an amplifier. If you already have speakers, you should look for an amplifier with the right amount of wattage—enough power to operate your speakers, but not more than they can handle. Verify that the impedance of the amplifier and speakers are the same.
What to look for
You should also think about what you want to amplify. Verify that the amplifier has both digital and analog inputs that you require. Make sure the amplifier has an output for the subwoofer if you’re using one.
Understanding the difference between a stereo receiver and a stereo integrated amplifier is crucial. Although they are close to one another, a receiver also has a radio built into it.
Nowadays, it’s not always necessary, but it’s still something to think about.
The Sony STRDH190 only provides analog inputs when it comes to wired inputs, but you do get five of them. While a dedicated phono input allows you to play your vinyl records, four inputs let you plug in CD players or streaming players.
You have two pairs of outputs for speakers, allowing you to switch between them or turn them all on at once. This receiver has a few drawbacks, but the main one is that the outputs won’t fit banana plugs and aren’t very sturdy.
On the other hand, this receiver does have Bluetooth wireless connectivity. Although this isn’t quite as high fidelity as connecting a high-quality source, its convenience is difficult to dispute.
Fosi Audio BT20A
You don’t have to worry about audio quality being compromised because this model uses class D amplification, which despite its small size allows it to pump out 100 watts per stereo channel.
The BT20A‘s controls are also kept to a minimum to match its small footprint. Three knobs for treble, bass, and volume control are located on the front of the device, along with a power switch and a status LED.
There is only one RCA line input available for analog signals. You also get a stereo speaker output, but despite the BT20A’s size, these outputs support larger banana plugs.
It shouldn’t come as much of a surprise that the BT20D lacks a subwoofer output given its simplistic design. However, if you want one, you can choose the slightly more expensive and larger Fosi Audio BT30D, which has a subwoofer output with a separate volume control.
There are numerous inputs and outputs on the PM60007. You get one coaxial, two optical, and five analog audio inputs, including a phono input. A moving magnet preamp is used in the phono input to accurately reproduce your favorite records.
There are more outputs visible than anywhere else in this lineup, according to the outputs. A dedicated subwoofer output and a line output for connecting an audio recorder connect the speaker outputs for Zones A and B.
The front of the device has all the controls you’ll need. You get knobs for volume, bass, treble, and balance in addition to a digital knob for choosing the input.
Marantz also provides a remote so you can control everything while lounging on the couch, assuming that’s what you prefer to do.
