*by X***D on 12 January 2022*

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.
