The D-150 is regarded by many as the Ultimate Classic Amplifier.

Rated in the 2012 "Absolute Sound Guide to Audio Electronics", as the "3rd MOST SIGNIFICANT AMPLIFIER OF ALL TIME", the Audio Research D-150 is the world's first powerful vacuum tube stereo amplifier.  

HP himself commented that because of its unparalleled faithfulness to the sound of real music, the D-150 is one of those rare products that no one ever forgets first hearing. 

The sound of the D-150 is not the only thing about it that's rare.  Audio Research built only 200 of these amplifiers, making it one of the most sought after collectables (as well as an amazing amplifier), that still rivals some of the best of today.
