New Maggie Owner; What amp????

For $1100, you can order a 150wpc Odyssey Stratos from Odyssey Audio. I highly recommend this Amp. It is a leader in the "value for the money" category. I have been so satisfied with this purchase, I have purchased a second unit and will have them converted to Mono blocks. Check the reviews at Audio Review. The Buzz is real.

I don't own mags but I did hear the 3.6 with a byston 4bst and it did sound quite amazing. With a 20yrs warrantee. I myself run a bat vk200 with aerius i's and I am very pleased with that combo. My friend ownes the little mags, I think they are the MG not sure but they sell for around $600 and he bought my bryston 3bst and that combo sounds very good. But you have the 1.6 so if you consider bryston go with the 4bst. Good luck pete

You need at least 100 Watts at 4 ohms but 150+ is better, and the amp will need to have high current output for the best sound. For the best sound also make sure the amp is FAST. The Maggies are fast but an amp that is quick and has some slam will get the best sound.
I've heard several integrated amps and liked a Goldmund SRI best ($1200 to $1700 used). I also found speaker cables made quite a difference and running biwired got the last little bit out of them.

I have the Audio Refinement Complete powering my MMG's. I'm happy with the sound but starting fresh I would go for more watts.

I have SMGa's in one of my systems and with respect to the question "How much power do Maggies need?" the correct answer is always MORE. They really need as much power as you can give them to get them to "bloom." I am using separates with an amp rated at 315 wpc @4 ohms and it is definitely NOT overkill. It replaced an amp rated at 200 wpc @ 4 ohms that frequently ran out of steam at high listening levels.

Given your stated desire for an integrated and your budget, the two that come immediately to mind would be a used Krell KAV300 or Musical Fidelity A300. Either of these should have the muscle necessary to drive your Maggies. I would be hesitant to buy anything with substantially less power.
