When I was buying the very best field recording equipment I was amazed at how light they were, new electronically balanced circuits are superior to iron transformers (even Jensen), but audiophile equipment uses iron transformers there is only 1 reason for that, tradition. The very best mixers in the very best studios don't use iron transformers. If you think about it you want a simple signal path therefore you don't want a box full of electronics. IC chips are used as preamps in the mixers doing the original recordings, IC chips are not heavy. Just another blatant example of companies taking advantage of rich audiophiles being taken advantage of.
