Hello Momma,
In all honesty, I am also not familiar with the other amps you mention but have heard good things about the Consonance M99 from those who have inquired about modifications for this piece.
I am obviously very familiar with the Jolida and can state that it is a very good value products and one that, for some reason, has been becoming much more popular in receiving modifications. Maybe because we mentioned we may hold off on modifications for it??
I think you couldn't go with any of your options but just based on amplifiers alone, it is very difficult to go further with recommendations without knowing more about the rest of your system, listening habbits and personal preferences.
