Is weight really mater?

I've been quiet on this front as I felt I might be nuts believeing weight matters in SS amps.... but it kept showing itself as being pretty evident.

my own exp with SS amps says Yes. There is a definite coorelation, more often than not. Indeed it is due to the power supplies in recent history, and this might change down the road with new power reserve technologies being nvestigated today.

I think though, the deal is however to make likewise comparisons.

comparing digital amps to non digital amps is not what I'd say is a likewise run off. Same for hollow state vs SS or switching amps.

Until or unless I get back into the 'lot's o' watts' camp, or rather if I do, I'd still want to stay with amp (s) under the 150 lb range. unless they've got their own wheels and are being set onto their own platform/stands. Getting something that heavy into a rack is a real chore. not to mention doing 'steps' with 'em on your shoulder or chest.

Rayooo,
Yes, yes and yes; you are correct. I just now realize that I'm not really comparing apple to apple here. Now I'm torned with another selection, class D or class A?

In class A or class A/B the weight corresponded mostly to the size of the power supply transformer, where bigger is usually better at any output rating, particularly for bass. However, in all things audio, there are more exceptions than rules.

Class D, or switching amps, like the JR 102, are much more efficient for the amount of power consumed and don't require such massive transformers.

I'm an old-timer and still prefer the heavyweights.

>>Now I'm torned with another selection, class D or class A?<<

Haha, Yes, I would be as well!

My suggestion would be, unless you have specific requirements like being more "green", or space restrictions etc. I'd stick with a good old A/AB aka Meat and Potatoes Amp that sounds right to you! Good luck!
