The DBS series was a fantastic amp.
The only drawback was the weight. They are the only amp I've used that didn't lose power when using a wah at volume.
I tried Trace, Hartke and even the eden, but nothing touches the flexibility of tone and tweakability of the Marshall.
The peak power alone of 4K w was unprecedented.
The VBA is also another killer head, but heavy again. Used across stages in a variety of countries.
I also know people that totally love the tones the jcm800 bass series created.
I recall reading an interview with Geezer, who said he had a marshall rig that they took to the states, but forgot to change the voltage and fried them before he moved to ampeg
