Amazing sound for a classic audio system. Song is: Jealous by Chromeo No Copyright Infringment intended.
Premiere essaie de ma Rotel RA-820 BX et wow un 25w bien gras j'adore!!

We left things in the last issue with a big question mark over the true worth of many of the circuit design claims of the amplifier manufacturers. Today amplifier design should be easier than it has ever been because there is a huge reservoir of past designs to build upon and now most circuit design is done using computer simulations so it is quick and easy to tinker away to your heart's content whilst observing the improvements offered by minor redesigns. Life is so much easier than in the days of yore when every component change involved a soldering iron and measurements could be slow and tedious. But are the results worthwhile?
Call me an old fogey if you will but my own observations of some of the younger engineers brought up on computer simulations is that when after days of circuit manipulation the distortion at 20kHz is halved there is great joy and a sense of achievement. But is any listener ever going to hear any difference? That is the ...
