No doubt that with large, high sensitivity speakers, and enough power, you will rock. But with stand mounted monitors, it does get more difficult. As far as I can tell, your Reference 3As have a higher sensitivity than any of the monitors recommended, yes, even the Legacy Audio Studio HD, listed as 93db Room sensitivity, which is 2-3db higher than anechoic chamber, so that puts it at about 90. Knowing that 3db is a double or half of power, the 85db monitors will need at least 300 watts to have the same relationship you currently have. If you must add power, then add to your current speaker.
Adding a sub could help, but adds more problems to achieve a coherent sound, and that is one of the strong qualities of the 3As.
Just curious as to what cables you are using, and if the MC275 still has stock tubes.
