Yamamoto and Classe Power Amp Reviews on 6moons

Wednesday, October 29, 2008

6moons has reviewed the Yamamoto A-09S tube stereo power amplifier (JPY 680,000-780,000). This is an “8wpc 300B stereo amplifier with tube rectification via 5U4G EML mesh plate.” Reviewer extraordinaire Srajan Ebaen liked it a lot and concluded:

This amplifier’s gain structure and drive potential, especially when fitted with EAT or EML 300Bs and EML’s 5U4G rectifier, exceeds the norm to make it suitable for somewhat counter-intuitive loudspeakers. Benign LF load impedance behavior remains important for best performance but 90dB voltage sensitivity isn’t too low at all even with a preamp of only 12dB of gain. In short, don’t overlook this amp based on its 8wpc paper specs.

Read the entire review for all the details.

6moons’ review of the Classe CA-M400 monoblock amps (AUD 24,000/pair) was written by Edgar Kramer and originally published in Australian Hifi magazine. Each of these amps “weighs 37kg and is rated at a powerful 400 watts RMS at 8 ohms and doubles-up to 800 watts into 4 ohms (not measured 20Hz-20Khz but at 1Khz).” On balance, Edgar concluded:

The Classé CA-M400 monoblock amplifiers are superbly built and — as far as amplification devices go — comprehensively featured. They have the hallmarks of expertly engineered electronics and they are bound to last a lifetime. What’s more, they have an engaging sound that is dynamic, smooth throughout the frequency range, accurate in detail and spatially massive. Classy indeed.
