Class D Technology

CLASS TD anyone Arcam’s P49

The P49 has been designed to leapfrog the competition with a massive 200 watts per channel into 8 ohms and 400 into 4 ohms. It delivers 50 watts in pure class A mode while allowing for huge extra power reserves from our latest generation class G topology that is both clever and efficient. During normal operation, distortion is measured in less than one part per million so that this massive power is deliver with total control and finesse.

There have been great strides made in improving audio sources and loudspeakers in recent years and the time is right to match them in the field of amplifier design. This ground breaking amplifier is a must audition amplifier for music lovers who understand that power is nothing without control.

You mean allowing the listener to feel the musical emotions? Like how the Atma-Sphere amplifiers and pre-amps does in spades :-)


Class D has never given me those intimate feelings during musical playback however for Studio recording, tracking and mixing on large studio speaker it can work, for Large Pro Audio Speakers it works even better. For Audiophile level setups i am not yet sure but i have not heard them all.

I have Class D Quested Amps setup for Home Theater use, powering up my Quested Rear channels all 12 of them with out a hint of strain, and it does a fine job. However my main front LCR Speakers use Active setup Class AB Quested Amps.

I Would like to Hear a Class D amplifier paired with a 300B Tube pre-amp.
