Transformer advice for stereo outs Yamaha PM2000 console?

Thought I'd ask you guys for some advice concerning some replacement transformers for the main stereo (matrix) out transformers in my PM2000 console.

The originals are 1:1, 600 ohm. They are pretty cool sounding, but I'd like something a little different. Something along the lines of a wide, tight, heavy, weighted but clean sound.

I have some JH 990C opamps on their way. I care enough about these main outputs that I might end up buying 2 or 3 pairs of transformers and seeing which I like best. But I'm just trying to narrow down my options. Ideas?

I hope it's not frowned on too much to ask for such subjective advice. 

i'd go with some Carnhill iron or Cinemag CMOB-1.
Good luck..
