“I will make no bones about this particular review it was frustrating but also at the same time uplifting and exciting in equal measure. It was frustrating in so much that I am sure there is more to hear from this wonderful amplifier but sadly I am unable to do that at the current time. However the results I was able to achieve were still breathtakingly good, especially with it hooked up to the Stereo Knight Magnetic Silverstone B&R Reference pre-amplifier, all be it its high output required me to use attenuators to better match to the ATM 300 input.”

“This was handy with Rock and strong electronic bass. The trance/dance beats from the Depeche Mode double single Fragile Tension/Hole To Feed had the power they deserve only with NFB. Undoubtedly my 60wpc solid-state Luxman handled all that much better, reached far lower, had better bass control and differentiation and hence also better timbre. Naturally lovers of 8-watt valve amps know these limitations and learn to live with them as the necessary sacrifice to the 300B.”
