    • The best ever
Color: Black
I immediately had to write this review because this amplifier is insanely amazing. 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. ... show more

    • After 14 months of light use this R300 Plus amplifier started blowing rectifier tubes
Color: Black
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... ... show more

    • Game Over
Color: Black
Right out of the box, the R300 delivered the most mesmerizing sounds I’ve ever heard. 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. ... show more

    • Try this. You'll like it.
Color: Black
I don’t normally review products, but I felt compelled to say a few words about the Willsenton R300 Plus amplifier. On the advice of several online reviewers, I decided to try this $1,600 Chinese-made amp with the understanding that if I didn’t like it, hey it’s Amazon … I could just return it. I will not be returning it. The sound of the R300 driving my Klipsch Cornwall speakers is gorgeous. At lower listening levels it’s luscious and creamy; at higher levels it’s as dynamic as any amp I’ve owed, never mind that it puts out a mere 8 watts. And while it sounds great right out of the box, after 50 hours it really starts to become magical. If you’ve got high sensitivity speakers as I do, you owe it to yourself to try it. ... show more

    • Rich and Deep - Gorgeous
Color: Silver Panel
I initially bought a Muzishare X7. I loved it. But I kept hearing about the 300b and decided to try it. I figured it would not be as good as the X7. I was wrong. The 300b is richer, deeper and with more dimensionality. It wasn't even close for the music I listen to - jazz, acoustic, rock. I can't say what it would sound like playing metal etc. But for my taste the 300b is pretty incredible. ... show more

    • You can do a lot better
Color: Black
Average. Sounds great but thin and harsh sounding with weird phase distortion . It might drip your jaw as a first amp. But the global negative feedback kills the magic of 300b sound . Makes up for it with deeper bass but overall not great sound. Came with a defective 6sn7 tube as well. Been trying to contact China hifi for return but they’ve been slow in response and don’t seem to want to take it back ... show more

    • 300B tubes are awesome
Color: Black
The type of tubes are great, but one can realize improvement with other "higher end" tubes, or (?) cryo. Don't be afraid of low power, but use with efficient speakers (Klipsch or several others like Tekton, Zu DW's, and many more.). Enjoy the tube experience and still save $$$.
