Some are less wrong than others but I still find amplifiers of Single Ended topologies to sound more natural than those that are not. This does not mean tubes either - Sugden's A21a is a single Ended amplifier and has successfully been selling for over 40 years because it embarrasses most competition where it actually counts - reproducing music. Meanwhile Musical Fidelity adds a new amp every 3 years, Bryston adds an S every now and then, McIntosh has blue lights and can't even decide on Tubes or SS (no direction), and the list goes on.
Not interfering with the debate...

but aside from the "coloration" and "tubey warmth" that SET is always accused of, lies wonderful accuracy and tonal supremacy. A great topology will also reveal excellent dynamics. I still listen to SS gear, but nothing touches my Golden Tube. I had long been a fan of the twin design by Harman Kardon and still am, but it's a second place finisher around these parts now. I own a 630 and 930, both are great SS examples.
