IMHO, if you want to listen at modest levels and not get the full dynamics of large orchestral music you can power the smaller maggies with "low" power tube amps. If you want the mid to large maggies to sing with tubes you will need Walcotts or upgraded Melos amps (buy at your own risk as service may be hard to find) or VTL etc., all of which cost a small fortune. For smaller MMGs why don't you try a smooth SS amp or if you want "cheap" but satisfying thrills match them with a good vintage luxman R115 (70 watt)or R117 (160 watt) receiver and use the CD bypass switch.
