The Willsenton R800i 300B 845 Tube Single-Ended Class A Integrated & Power Amplifier is a remarkable piece of audio equipment that has captured the attention of audiophiles worldwide.
This review will delve into the features, performance, and user experiences of this high-end amplifier, helping you decide if it’s the right fit for your audio setup.
I have owned a Willsenton R800i 845 for about 1.5 years and it has completely transformed my audio experience. The sound quality is impeccable, and I can confidently say that I will never go back to transistor amplifiers again.
While there are some potential upgrades one could make, such as improving fuses or tubes, the stock configuration is more than sufficient for most systems under $25k. The amplifier has proven to be a fantastic investment in my audio journey.
Build Quality and Design
The Willsenton R800i 300B 845 Tube Amplifier boasts exceptional build quality, highlighted by its hand-welded point-to-point connections. This meticulous craftsmanship ensures durability and reliability, making it a long-term investment for audiophiles. The amplifier also features high-end EI type single-ended output transformers, which contribute to its robust design and superior sound quality. Additionally, the use of high-efficiency toroidal power transformers with Z11 cores and special materials further enhances its performance and stability.
Power and Performance
This amplifier is equipped with two high-end EI type single-ended output transformers that offer a high-quality broadband response. The power-on high-voltage delay and mute delay function, which lasts about 30 seconds, ensures the safety and longevity of the tubes. The amplifier can handle both 845 and 805 tubes, each offering distinct sound characteristics. The 845 tubes are known for their smooth sound, ideal for vocals and high-efficiency speakers, while the 805 tubes provide high power suitable for dynamic music genres like symphony and jazz.
Sound Quality
Users have praised the Willsenton R800i for its outstanding sound quality, describing it as a life-changing audio experience. The amplifier delivers a warm, rich sound that is often associated with tube amplifiers, making it a favorite among audiophiles. Upgrading the tubes can further enhance the sound quality, offering even more detailed and dynamic audio. The use of a Japanese ALPS high-end potentiometer ensures precise volume control, although some users have noted that the volume control steps are too large and prefer using a separate pre-amp.
Technical Specifications
The Willsenton R800i features independent high-voltage and filament power supplies, which contribute to its efficient performance. The Z11 iron core used in the output transformers and power transformers ensures high-quality broadband response. The amplifier also includes a power-on high-voltage delay and mute delay function of about 30 seconds, which protects the tubes and extends their lifespan. The high-end potentiometer from ALPS ensures accurate volume control, although some users may find the volume steps too large and opt to use a separate pre-amp.
Tubes and Compatibility
One of the key features of the Willsenton R800i is its compatibility with both 845 and 805 tubes.
