Review: Threshold CAS-2 Amplifier
Category: Amplifiers
I can speak with some authority on the Threshold CAS 2 for I have owned one for several years now. The Cas 1 and Cas 2 were the direct result of the Nelson Pass white paper on Cascode circuit design. This white paper was and remains truly ground breaking. However design is just the first part. The build quality on these amps is second to none. The sound quality and musicality is astounding. The Cas 2 is true dual mono producing 100 watts RMS into 8 ohms.The CAS 2 was one of the first high current amps produced,12 amps instaneous 5 Amps continous.The CAS 2 employs 24 high speed,150 watt output devices for a combined instantaneous reserve of of 3,600 watts. Every part used in the CAS 2 was tested at 150% maximum,before the part was deemed worthy for the build.Frequency bandwidth is +0dB - 3dB 1Hz through 100KHz. +- .1dB 20 Hz through 20kHz at 100 watts per channel. THD is no greated than .03%.With the above being said it is little wonder,so few of the these show up in the used market. People that have them--keep them. Thats just how good they really are and remain so today. The Threshold Cascode amplifiers are a music lovers dream,and after all that what it is really all about. Now some 20 years plus since these were new,this is the ultimate validation of Nelson Pass Cascode design.Find one if you can and cherish it as a true legend of audio history.
