Is solid state obsolete?


Let's cut to the chase. Mosfet, Jfet, transistors, are they a past technology like 78 rpm? IC based amps are here and here to stay. Are the days of Krell, Gamut, Accuphase, Clayton, McCormick, Rowland, Boulder, etc. gone? A tube pre amp and an IC based power amp, can it be the best combo? Comments please.

The key is matching the amp to the speaker. There is no such thing as an amp that will work well with all speakers or a speaker that can be driven well by any amp.

The best? I don't think so, SS devices have inherent distortions that have to be dealt with with feedback, but it can be acceptable if the power amp is mated with the proper speaker.

There is actually no practical difference in the two. An IC (integrated circuit) is nothing more than a bunch of Mosfets, Jfets, and/or bipolar transistors and bias devices integrated into a single package that makes it easy for a designer to build an amp. You could build the same amp with discrete devices. There is really no difference in the performance of an IC amp or one made of discrete transistors.
