Magneplanar 1.7 and low power/tube amps


Hello,
I am moving through to a new set of speakers. I demo'd a set of the 1.7's running with fm acoustic amplifier (80w/channel according to the dealer). I have an LFD Zero and also an audio space 300B (21w/chan). Would anyone have experience with a similar output ss or tube setup with these speakers? I realise the more power perspective but my listening is really at lower volumes. The Maggies impressed me immensely, just wondering if others have real world experience with low power matching with these speakers.
Thanks in advance!

I've MEASURED my Maggies with a DVM. Not the most accurate, but carefully watching I can catch the PEAK voltage go by. Based on that, I add 20% for meter latency and use 4.5 ohms to compute power. For my 1.6s, at mid-loud / comfortable, I've never seen more than 10vac go by, even with the +20%.

This works out to 2.2amps at 22 watts.

During normal TV watching, I've never seen more than about 6v, with the 20% fudge factor.

I'm guessing that 15 clean watts, with 3db headroom may be on the 'low' side of even minimal. I would DOUBLE my 22 watts, add another 'fudge' and say 50 watts MINIMUM for any meaningful music listening. DOUBLE again and you'd be at minimal SAFE power.

I know, I'm nuts, but my ICE amp puts out 500+ per side into 4ohms, at probably 50 or 60 volts. I'm scared to test it!
I'm told the MOSFET's on my LFD will handle a 12Amp load for transients. I'm going to take it into the shop and see how we go on the stuff i am familiar with.
The ICE amp I have is rated at 35 or 40 amps.....don't 'member.

don't forget, you've got what....a 4 amp fuse?
If at the 12 amps, the voltage of the amp has sagged to 12 volts, that's still just 144 watts....

I'd hope some amp guru type will drop by.

any place you could take your amp and listen to some Maggies? That's the acid test.
