I'd be surprised if the loudness issue was due to the transformers. Decware seems pretty proud of the iron he uses. There is thread on another forum comparing the build/parts of the Dynamo to Decware and FWIW, the decware seems to get more respect from the engineer type guys with specific mention of the capacitors and wiring layout.
I know there is another poster here on audiogon who uses a 4 watt Decware and feels it drives his decapos perfectly fine. Ultimate loudness can be a very subjective thing and two different people can have very different ideas about what is and isn't loud enough even in the same room with the same equipment.
