My old Linear Power collection still outperforms 99% of today's amps and will be working long after the industry switches to a 36V system. Why downgrade? Today's amps are not better than those of yesteryear. If anything, my testing here at work has proven that the saying, "they don't make 'em like they used to" is VERY true. Just because it is newer doesn't mean it will perform better or last longer.
