I have owned many amplifiers and this is hands down on another level. The construction of this amplifier is soo gorgeous, soo beautiful, soo well made and heavy it left me speechless. This amplifier is made by true craftsman and engineers. The hard work that went into this is breathtaking. It has an automotive paint job! It has a beautiful blue smooth paint job! This kills anything a western brand makes and then pisses on it. The value for the money is unbelievable. I don't know how Willsenton can make a profit at this price but I am extremely grateful and will save up to purchase the rest of their products because aftering powering it on this amplifier sounds as impressive as it looks. The sound is the greatest thing I've ever heard. After a life of solid state amps and a few class d I went to tubes first with tube headphone amplifiers and this is my first 300b speaker amplifier. At 8 watts this plays louder, more musical, smoother and with more crystal clear authority than any solid state or class d I've ever heard. I have this amp hooked up to my fully upgraded tekton pendragons and the sound is magical. Crystal clear mids and highs, smooth, natural, life like, and it has slam and authority. Yes, this does not play softly it is perfectly dynamic. This amp plays rock, vocals, instrumentals and pop with authority and ease. I have the Volume set at 9 o clock and going any higher it gets very loud but still crystal clear and smooth. It is unbelievably linear. Thank you willsenton for making this product at such a great price. This easily competes with products many times higher in price and I am extremely grateful to be able to own a 300b of this very high quality. If anyone is interested I can tell you honestly it's more than worth it. You will listen to your whole library all over again with this because it's that good. It brought my music to life. Review: After 14 months of light use this R300 Plus amplifier started blowing rectifier tubes - Unit looks really good, and sounded (past tense) pretty decent. I put really expensive tubes in it, like Cryotone and Western Electric 300B but found that it didn't really make a big difference in the sound. It always sounded "ok". My complaint is that after 14 months of fairly light use (couple of hours/week) the amp started blowing rectifier tubes. There's 2 of them, $175 each so $350 bucks of sparkling and sizzling death every time you turn on the amp with new tubes. Which I did exactly twice, so $700 down the drain. Amp is out of warranty, of course. Questionable whether it is worth getting it repaired. Now I have a really good looking boat anchor... ## Features - ONE YEAR WARRANTY.Willsenton R300 PLUS is an integrated Amplifier, it is a Power Amplifier too (there is a group Power amp input), it is a Headphones amp, too. - Pure hand-made, Point to point manual welding.Single-ended pure Class A tube Integrated amplifier - The body of Willsenton R300 PLUS use classic Blue piano paint. - Use a new Reamoter CNC in one block aluminum alloy, easy to change the battery, and looks nicer. - The high voltage uses two customized 5AR4 vacuum tubes for full-wave rectification.The front stage uses an imported Tung-Sol 6SL7 GT for amplification and two former Soviet 6SN7 vacuum tubes for push.The rear stage uses two customized 300B vacuum tubes for single-ended Class A power amplification. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CRB9C9KF | | Best Sellers Rank | #121,589 in Electronics ( See Top 100 in Electronics ) #748 in Audio Component Amplifiers | | Brand | Willsenton | | Built-In Media | Power Cord, Remote Controller | | Color | Silver Panel | | Customer Reviews | 3.8 out of 5 stars 41 Reviews | | Enclosure Material | Aluminum Alloy | | Manufacturer | Willsenton | | Material | Aluminum Alloy | | Mfr Part Number | R300 Plus Silver | | Model Number | R300 Plus Silver | | Number of Items | 1 | | Output Channel Quantity | 5 | | Warranty Description | one year warranty | ## Product Details - **Brand:** Willsenton - **Color:** Silver Panel - **Material:** Aluminum Alloy - **Number of Items:** 1 - **Output Channel Quantity:** 5 ## Images ![R300 Plus Tube Amplifier 300Bx2 Single-Ended Class A Integrated Amplifier Power Amplifier Headphones amp All in One (Silver Panel) - Image 1](https://m.media-amazon.com/images/I/81bpT0t9ikL.jpg) ![R300 Plus Tube Amplifier 300Bx2 Single-Ended Class A Integrated Amplifier Power Amplifier Headphones amp All in One (Silver Panel) - Image 2](https://m.media-amazon.com/images/I/81c+In59rDL.jpg) ![R300 Plus Tube Amplifier 300Bx2 Single-Ended Class A Integrated Amplifier Power Amplifier Headphones amp All in One (Silver Panel) - Image 3](https://m.media-amazon.com/images/I/81nZ7bVVnVL.jpg) ![R300 Plus Tube Amplifier 300Bx2 Single-Ended Class A Integrated Amplifier Power Amplifier Headphones amp All in One (Silver Panel) - Image 4](https://m.media-amazon.com/images/I/81aK+J37laL.jpg) ![R300 Plus Tube Amplifier 300Bx2 Single-Ended Class A Integrated Amplifier Power Amplifier Headphones amp All in One (Silver Panel) - Image 5](https://m.media-amazon.com/images/I/81zRrp692ZL.jpg) ## Available Options This product comes in different **Color** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ The best ever *by X***D on January 12, 2022* I immediately had to write this review because this amplifier is insanely amazing.

And after only eight hours, it’s louder, clearer, and more holographic than all other single ended triode amps I’ve owned or heard. In my world, only SET amps can compete. My high end stereo hobby spans many decades and I don’t think I’ll be looking for another amp. The way this thing brings voices into the room is eerily realistic. 300B is no joke! While listening, I felt like a knight on a three dimensional chess board of musicians, as if I could walk amongst them. Finally, the sound is so magical, I get lost in it; making me forget any thought of the science and technology involved in its production. And at the end of the day, isn’t that what it’s all about? The R300 is a flawless jewel inside and out. ## Frequently Bought Together - Willsenton R300 Plus Tube Amplifier 300Bx2 Single-Ended Class A Integrated Amplifier Power Amplifier Headphones amp All in One (Silver) - Micca 14 Gauge Pure Copper Speaker Wire, 12 Feet (4 Meters 13.1ft Actual), 2 Pack Pair, Gold Plated Banana Plugs Connectors, Soldered Construction, Slim Design, 245 Strands, For Stereo or Home Theater - Primeda Auidophile 2RCA Male to 2RCA Male Stereo Audio Cable,Gold Plated | 4N Oxgen-Free Copper Core (6 Feet (2M)) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.cy/products/599091815-r300-plus-tube-amplifier-300bx2-single-ended-class-a-integrated](https://www.desertcart.com.cy/products/599091815-r300-plus-tube-amplifier-300bx2-single-ended-class-a-integrated) --- *Product available on Desertcart Cyprus* *Store origin: CY* *Last updated: 2026-07-14*
