#### **Cons**
Despite its many virtues, the RCA VT64 800 is not without drawbacks, particularly for modern users or those with different priorities:1. **High Cost** The VT64 800 is expensive, especially for a used unit. Prices can range from several thousand to tens of thousands of dollars, depending on condition and rarity. This makes it inaccessible to many audiophiles on a budget.
2. **Maintenance and Reliability** Vacuum tube amplifiers require more maintenance than solid-state units. Tubes degrade over time and need periodic replacement (typically every 1,000 3,000 hours of use). The amplifier may also require occasional adjustments or repairs, which can be costly if done professionally.
3. **Power Consumption** Tube amplifiers draw significant power, especially when running at full output. This can lead to higher electricity bills compared to modern, energy-efficient solid-state amplifiers.
4. **Bulky and Heavy** The VT64 800 is a large, heavy unit, which can be impractical for smaller setups or those with limited space. Its size also makes it less portable than modern amplifiers.
5. **Limited Modern Features** Unlike contemporary amplifiers, the VT64 800 lacks digital inputs, built-in DSP, or advanced connectivity options. It is primarily designed for analog signals, which may limit its usability in modern home theater or multi-room audio systems.
6. **Learning Curve** Operating and maintaining a tube amplifier requires some knowledge of vacuum tube technology. Users may need to learn how to replace tubes, adjust settings, and troubleshoot issues, which can be intimidating for beginners.
7. **Subjective Preferences** While many audiophiles love the sound of tube amplifiers, others prefer the clarity and precision of solid-state units. The VT64 800 s sound is polarizing, and not everyone will appreciate its warmth and slight distortion.
8. **Availability of Parts** Finding replacement tubes or parts for a vintage amplifier can be challenging. While some tubes are still available, others may require special ordering, which can delay repairs or upgrades.
