As this discussion demonstrates! There are numerous approaches to improving one's audio system,. Spread the wealth certainty has merit. I probably feel more strongly about the impact of amplification than some others here.
Charles, your take is par for the course for SET amp advocates.
There are many different ways to audio nirvana.
The most common mantra is the 'speakers first' crowd. While others will insist that the source is the key to audio heaven. Others, like yourself, mostly SET fans, insist that the amp is the key to the system. There are even a few outliers who will beat the drums that wire is the key to true happiness. Then there is my group preaching system balance.
Digital? Analog? Computer Audio? SET? Class D? Class A? Passive or active preamp? Tube or solid state? Cables matter, or not? Tweaks??? Fuses???
So many choices. In the end, everyone must make their own personal choices as to what works best for them.
