Transformer stepup size

I used a K&K and a Microgroove. They both worked very well. Then I bought a Supratek, so I don't need the stepup any more. So, I sold the Microgroove and kept the K&K in case I ever need another stepup.

Size don't matter. Does that answer your question?

I can tell you on my personal experience the same thing: Performance Does!

Thanks for the responses. But my question remains unanswered as to the technical merits of a much (4 to 5 times) larger design in terms of overall performance. My ears seem to detect a fuller, deeper in bass extension with the larger design. Moreover, the cost seems proportional to the size of the stepup as well. Any actual comparative experiences with magnetic stepups?
