Most Wanted Components Award

 

"The difference in their power is it has a "charm" to it. I've had powerful components before but none were both powerful and delicate. The Final 845s drove my Conspiracy loudspeakers with no problems. It's all there: the gorgeous midrange that one expects (especially from an SET), very neutral, neither euphonic or syrupy. The Final 845s had extremely natural treble extension, very extended and sweet. They presented a beautiful soundstage, big, wide, deep, and very three dimensional. Damit, I can’t put my finger on it exactly - but the reproduction of music, especially un-amped classical music - simply sounds more natural."

 

"The Master Sound Final 845s amps have opened my eyes and ears to the beauty of SETs. They have shown me what tube magic is when done correctly. I’ll be sad when trucker picks up the amps next week and I’ll be searching for more tubes amps to review in the future. Until then stay tuned! The Master Sound 845 mono amplifiers are my Stereo Times “Most Wanted Components” award winner. Highly recommended!!"
