Class A equipment used to be priced in the hundreds of thousands, but that has changed significantly. Now, high-quality amplifiers are available at a fraction of that cost. Check out our analysis of power amplifiers ranging from five to ten thousand dollars.
Manley Laboratories Mahi
A timeless tube classic, the Manley Laboratories Mahi features four EL84 pentodes, delivering a power range of 14 to 41 watts based on the switching type (triode and ultralinear modes, respectively) and speaker impedance. This unit is best suited for a 6-ohm load and is not advisable for speakers with an impedance significantly below 4 ohms. Despite its limitations, when set up properly, this device can truly captivate you with its remarkable, fluid, and “mercurial” sound.

PS Audio Stellar M1200
The PS Audio Stellar M1200 presents a striking visual contrast to the company’s previous bulkier models. It features a cascade design utilizing a Psvane 12AU7-TII tube alongside a class D configuration from ICEpower. This amplifier is a powerhouse, delivering 600 W at 8 Ohms and an impressive 1,200 W at 4 Ohms. Its capability to handle demanding “crowbar” speakers is remarkable. However, what stands out is that in their quest for immense power, they have not compromised on quality; the device exhibits excellent temporal accuracy, though it does fall slightly short in microdynamics when compared to true High End standards.

McIntosh MC462
The MC462, McIntosh’s most powerful stereo amplifier, boasts an impressive output of 450 watts per channel across 2, 4, or 8 ohms. This amplifier, characterized by its distinctive “arrows,” operates in a unique AB class configuration. Each phase of the audio signal is amplified by a complete push-pull output section, effectively utilizing two fully functional push-pull amplifiers per channel, with their outputs merged through autoformers. The audio performance of the McIntosh MC462 is nothing short of exceptional, showcasing remarkable dynamics and superb detail.
