The NAD 1721-860A Integrated Amplifier is a popular choice for audiophiles looking for a high-performance and versatile amplifier. Here are some pros and cons that might help you decide if this amplifier is the right one for you:

1. High Power Output: The NAD 1721-860A delivers a considerable amount of power with a continuous power output of 86 watts per channel into 8 ohms and a peak power output of 172 watts per channel. This makes it suitable for driving a wide range of speakers.

2. Versatile Connectivity: This integrated amplifier comes with a variety of connectivity options including two pairs of RCA line-level inputs, one pair of RCA phono inputs for a turntable, and a 3.5mm auxiliary input. It also has a pre-amp output for use with an external power amplifier.

3. High-Quality Build: NAD is known for its high-quality builds, and the 1721-860A is no exception. It has a solid aluminum front panel, a heavy-duty toroidal transformer, and a well-designed circuit board.

4. Wide Frequency Response: The amplifier has a frequency response of 20Hz to 20kHz, which ensures that it can handle a wide range of music genres and frequencies.

5. Great Sound Quality: The NAD 1721-860A delivers a clear, detailed, and well-balanced sound with excellent dynamics and a wide soundstage.

1. Limited Bluetooth Connectivity: The amplifier does not have built-in Bluetooth connectivity, which might be a drawback for some people who prefer wireless streaming.

2. No USB Input: The amplifier does not have a USB input, which means you cannot directly connect and play music from a USB drive.

3. No Subwoofer Output: If you are planning to use a subwoofer, you will need to purchase an external subwoofer amplifier.

4. No Remote Control: The amplifier does not come with a remote control, which might be inconvenient for some users.

The NAD 1721-860A Integrated Amplifier offers excellent power output, versatile connectivity, high-quality build, wide frequency response, and great sound quality. However, it lacks Bluetooth connectivity, USB input, and a remote control. If you can live without these features and are looking for a high-performance integrated amplifier, the NAD 1721-860A is a great choice.

If you are looking for an integrated amplifier with Bluetooth connectivity, USB input, and a remote control, you might want to consider the NAD D 3045 Hybrid Digital Wireless Amplifier or the NAD C 316BEE V2 Integrated Amplifier. However, if you prioritize power output, versatile connectivity, high-quality build, wide frequency response, and great sound quality, the NAD 1721-860A Integrated Amplifier is an excellent option.
