Classe Audio has released a new range of four high-end Delta series amplifers. The four new models are the 300 watt CA-M300 and 600 watt CA-M600 monoblocks, the stereo CA-2300, and the multichannel CA-5300, which provide 2x300 and 5x300 watts. All of the new Delta series amps feature a new miniaturized driver-stage circuit with shorter signal paths, and a new active thermal management system called "ICTunnel".
The ICTunnel system allows the amplifier
to warm up to optimal operating temperature within 15 minutes, and then holds that temperature regardless of output levels for the best performance possible. A new power supply design also allows for standby power usage of just 0.5W. Prices for the new Delta Series are $5,500 for the CA-M300, $7,000 for the CA-M600 and CA-2300, and $9,500 for the CA-5300.
