How Much Push/Pull Tube Power for Maggies

I actually made some measurements of the voltage driving a MG 1.6 when playing at an admittedly very loud level with demanding music. I concluded that my 600 watt/4 ohm amplifiers are not really overkill. They approached clipping. However, most of the time, and with a more reasonable volume level, 350 watts ought to be sufficient. I am now using CI D200 amps that are good for 350 watts at 4 ohms, and the 600 watt amps are busy driving subwoofers.

Your little tube amp will certainly drive the Maggies, and it will sound good, but you will not realize the real potential of the Maggies until you get a much more powerful amplifier.

thoug it has a meager 75wpc rating, the mac mc275 will drive most maggies just fine.

Rogue 120 with Maggie 1.6 will play loud enough for most but was (oddly) lifeless sounding to me. An Innersound ESL amp (SS) with 600+ watts sounded much more vibrant and alive.

yes 40 watts will work for low volume listening but you will find yourself wanting more power if you want any kind of volume.

FWIW I ended up selling my 1.6s because I got frustrated looking for a suitable amp that I could afford.

Bottom line? It appears that you will be able to drive a pair of Maggies That's it. Won't have any of the fun that Maggies can give you. Not with 40wpc. 200+ now you're beginning to talk. Look for other speakers or get your Maggies, but be ready to splurge big time for a new amp. They need oodles of high quality watts. Can get very expensive. I loved my Maggies, back in the 70s. Still as inefficient now, as they were then...warren

For what it is worth, I drove a pair of MG2B's with a Cary SLA 70 Sig (35w class A P-P w/EL34) and they sounded fantastic. Much will depend on your listening tastes and the size of the room. Check over on the MUG forum at the Audioasylum.
