---
### **Cons**
1. **Outdated Technology**
The KA-28 is a **1990s-era amplifier**, meaning it lacks modern features like:- **Digital inputs (S/PDIF, USB, or Bluetooth)** No direct connection to modern DACs, streaming devices, or smartphones.
- **Networking or internet radio** Cannot connect to services like Spotify, Tidal, or Qobuz.
- **Advanced DSP or equalization** No built-in room correction, parametric EQ, or multi-channel processing.
- **USB playback** While it can play CDs, it cannot read USB drives or modern digital formats natively.
2. **Limited Connectivity Options**
The analog inputs and outputs are sufficient for basic setups, but if you want to integrate modern sources (e.g., a high-res DAC, streaming device, or computer), you ll need additional converters or interfaces.
3. **No Headphone Amplifier**
Unlike many modern amplifiers, the KA-28 does not include a dedicated headphone output, which can be limiting for listening to high-impedance headphones.
4. **No Subwoofer Output**
It lacks a dedicated subwoofer output, so if you re using a powered subwoofer or need low-end reinforcement, you ll need to route the signal through an auxiliary output, which may not be ideal.
5. **CD Player Limitations**
While the CD player is functional, it does not support:- **High-resolution audio (e.g., 24-bit/192kHz)** The CD format is limited to 16-bit/44.1kHz.
- **Modern CD formats** No support for CD-R/CD-RW or high-density CDs.
- **Error correction for damaged discs** Older CD players may struggle with scratched or poorly pressed discs.
6. **No Remote Control**
The KA-28 lacks a remote control, which can be inconvenient for larger setups where you want to adjust volume or inputs without getting up.
7. **Potential for Obsolescence**
If you plan to upgrade your system in the future, the KA-28 s lack of modern interfaces may require additional gear (e.g., a DAC, preamp, or network player) to keep up with current audio trends.
8. **No Built-in Clock or Timekeeping**
Some audiophiles prefer amplifiers with a clock or timekeeping function for synchronized playback, but the KA-28 does not include this feature.
9. **Limited Brand Support**
Kenwood is no longer a major player in high-end audio, so finding replacement parts or service may be difficult compared to brands like Marantz, Yamaha, or Denon.
10. **No Multi-Channel Outputs**
The KA-28 is strictly a **2-channel amplifier**, meaning it cannot drive surround sound systems (e.g., 5.1 or 7.1). If you re interested in home theater, you ll need a separate AV receiver.
