Which: $1000 MM or Transformer and $400 MC?

Look at high output MCs such as Benz Glider or ACE, or Sumiko Black Bird.

yup, that would be my initial suggestion, but include the following also, because they are good even though some are MM:

- Dynavector 20X-H
- Clearaudio Virtuoso 2 (but the Maestro Wood would be worth the stretch)
- Sumiko Blackbird

What about the possiblity of a phono preamp that can handle LOMCs without an SUT?

A number of solid contenders in this category.

Why are you holding on to the Aikido? Sound quality, sentimentality? I ask as someone who ran DIY speakers for longer than really made sense considering what I paid for partnering components for them.

High output MC has my vote too. There is also the dynavector DV20XH that would do. I have one and I like it a lot.
