Mono active speaker at amazing sound quality for playing music in any room by connecting your playback device.
Single ended class A.
Single ended at a few watts can sound fantastic and loud. With warm sound, fantastic treble, midrange, bass.
It is no coincidence that such transfer characteristics (low distortion at low level and gradual distortion at higher signal amplitude) are used in mastering for consumer records or radio, YouTube etc.
They give a high average level.
The amp speaker can be mono. Just like a pebble thrown on a lake. Great definition, warm sound, excellent localization. Excellent 3D virtual effect as the brain localizes naturally the source at any position of the listener in the room.
If using stereo and the listener is not equidistant from the speakers then 2 Madonnas for example are heard, one at each speaker which is unnatural.
The Pleiades amp speaker signsl path is very simple. Just a transistor. A biasing resistor from collector to base. The speaker directly connected to the collector. A battery with fuse. See a previous euroelectron post for full description of the Pleiades power amplifier. A high quality 2 way or 2 way coaxial or full range speaker can be used.
Low power consumption. The sound quality is such that even 1 or 2 watts power output may be enough. Or because of it or class A?
If the 3D effect is to be upgraded perhaps more such amps may be used one for each instrument. Great for learning music.
But even 1 speaker amp sounds amazing with all channels sent to it.
The excellent localization sounds warm, untiring and aid the brain to concentrate at a cocktail party. One could concentrate at music or discussion more easily without the music atmosphere being obtrusive. (The Cocktail Party effect may operate more effectively).
If a stereo amp for example is sending to 4 speakers in a living room the sound is thick and unclear. Like throwing 4 pebbles on a lake.
The concept of a mono reproduction came about from the little kid Ionas inquiring why 2 speakers?
