### **Pros and Cons of buying a Horner Automation HE693 DAC420**

The **Horner Automation HE693 DAC420** is a high-end digital-to-analog converter (DAC) designed for audiophiles seeking superior sound quality in a compact form factor. Below is a detailed breakdown of its advantages and disadvantages, followed by a concluding recommendation.

---

### **Pros**

1. **Exceptional Sound Quality**

- The HE693 DAC420 is built around Horner Automation s proprietary **DAC420 chip**, which is known for its high-resolution performance and dynamic range. Many users report a rich, detailed, and accurate audio reproduction, with minimal distortion and excellent transient response.

- It supports **up to 384 kHz/32-bit PCM** and **DSD64**, making it suitable for high-resolution audio formats.

2. **Compact and Modular Design**

- The unit is small (approximately **120 x 120 x 30 mm**) but features a **modular design**, allowing users to customize their setup. It can be paired with Horner s **HE693 power supply** or used with external power sources.

- The **front-panel controls** (input selection, volume, and output switching) are intuitive and well-placed, making it user-friendly.

3. **Versatile Input Options**

- **Optical (TOSLINK)**

- **Coaxial (S/PDIF)**

- **USB (with built-in USB-to-digital conversion, though some users prefer external DACs for USB)**

- **Analog inputs (via the HE693 module, if expanded)**

- This flexibility makes it compatible with most modern audio sources, from smartphones to high-end streaming devices.

4. **High-Quality Construction**

- Horner Automation is known for its **premium build quality**, with solid metal construction, high-grade components, and careful attention to shielding and grounding. This contributes to a clean and stable audio signal.

- The unit includes **proper filtering and power conditioning**, which helps reduce noise and interference.

5. **Good Value for a High-End DAC**

- While not as expensive as some flagship DACs (e.g., Chord Electronics, ESS Sabre-based designs), the HE693 DAC420 offers **near-high-end performance** at a more accessible price point. It is often praised for its **bang-for-buck ratio** in the audiophile market.

6. **Compatibility with Horner s Ecosystem**

- If you already own other Horner Automation products (e.g., the **HE693 power supply, HE693 preamp, or HE693 modules**), this DAC integrates seamlessly into their modular audio system.

- Horner s **software tools** (e.g., their DAC control app) allow for fine-tuning of settings, which can enhance performance for specific audio sources.

7. **Low Distortion and Wide Dynamic Range**

- Audiophile tests and user reviews frequently highlight the **low harmonic distortion** and **high dynamic range** of the DAC420 chip. This results in a more natural and immersive listening experience, especially for classical, jazz, and film music.

8. **Easy Installation and Setup**

- The unit is straightforward to install, with clear labeling and minimal wiring requirements. It does not require complex calibration, making it accessible to both beginners and experienced audiophiles.

---

### **Cons**

1. **Limited USB Performance (Without Expansion)**

- While the DAC420 supports USB, its **built-in USB-to-digital conversion is not as refined as dedicated USB DACs** (e.g., those using the **ES9038Q2M, AK4490, or ESS Sabre**). For the best USB performance, pairing it with an **external USB DAC module** (e.g., Horner s **HE693 USB module**) is recommended.

- Some users report that **streaming services (Spotify, Tidal, Qobuz) may not sound as polished** as with a dedicated USB DAC.

2. **No Built-in Amplification**

- The HE693 DAC420 is a **standalone DAC only** it does not include an amplifier. If you need headphone amplification, you will need to pair it with an **external headphone amp** (e.g., Horner s **HE693 preamp** or a dedicated amp like the **Schitt Modi 1200**).

- For powered speakers, you will need a separate **amp or AV receiver**.

3. **No Bluetooth or Wi-Fi**

- Unlike some modern DACs, the HE693 DAC420 **does not support wireless connectivity**. If you rely on Bluetooth or Wi-Fi streaming, you will need a separate device (e.g., a **Raspberry Pi, Roon Ready device, or a DAC with built-in Wi-Fi**).

4. **Modularity Adds Complexity (For Some Users)**

- While the modular design is a strength, it can also be a **drawback for those who prefer simplicity**. Expanding the system (e.g., adding a USB module or preamp) requires additional components and setup, which may not appeal to everyone.

- Some users find Horner s ecosystem **overkill** if they only need a basic DAC setup.

5. **No Direct Analog Input (Without Expansion)**

- The HE693 DAC420 is primarily a **digital-to-analog converter**. If you want to connect analog sources (e.g., turntables, keyboards, or analog mixers), you will need to pair it with Horner s **HE693 preamp module** or another preamp.

6. **Price Sensitivity Compared to Competitors**

- While the HE693 DAC420 is reasonably priced for a high-end DAC, some audiophiles may find **alternatives (e.g., Chord Hugo, ESS DACs, or even some Schiit DACs) to offer better performance for the money** in specific areas (e.g., USB, analog inputs, or wireless).

- The **DAC420 chip is proprietary**, and while it performs well, it may not have the same level of third-party optimization as chips like the **AKM AK4490 or ESS Sabre**.

7. **Limited Brand Recognition Outside Audiophile Circles**

- Horner Automation is a **niche brand**, and while their products are highly regarded in audiophile communities, they may not be as well-known as mainstream audio brands (e.g., Cambridge Audio, Denon, or Yamaha). This could make finding support or replacement parts slightly more challenging.

8. **No Overclocking or Advanced Firmware Tweaks**

- Unlike some high-end DACs (e.g., those from **Chord, ESS, or Topping**), the HE693 DAC420 does not offer **overclocking or extensive firmware customization**. This limits advanced users who may want to push the DAC to its absolute limits.

---

### **Conclusion**

The **Horner Automation HE693 DAC420** is a **well-engineered, high-performance DAC** that excels in **digital-to-analog conversion**, offering **exceptional sound quality, modular flexibility, and solid build quality**. It is particularly well-suited for audiophiles who:

- Prioritize **high-resolution audio** (up to 384 kHz/32-bit and DSD64).

- Appreciate **clean, detailed, and dynamic soundstage** reproduction.

- Want a **compact yet expandable** solution within Horner s ecosystem.

- Are willing to pair it with an **external amp or USB module** for full functionality.

- Need **wireless streaming** (Bluetooth/Wi-Fi).

- Want a **standalone solution with built-in amplification** (headphone or speaker).

- Prefer **off-the-shelf USB performance** without additional modules.

- Are looking for **maximum customization or overclocking** options.
