I'm not sure if you're still deliberating on speaker options at this stage given the date of your post, but FWIW If you already like Magnepan's house sound, i'd choose the 3.6R's every time for value with the following caveats;

- You're right; you'll need a more powerful amp of atleast 200 watts with plenty of current which doubles down to 2 ohms to get the best out of them. Basically the more power you can throw at them the better.
- They ideally need plenty of room behind them & an even wall due to their dipole radiation pattern, but if you've got a suitable room & enough juice, i'd say go for it!

I have a couple speakers in my hand and this are the only I know that match my ears, don't know if it match with your current settings but have a time in looking at the details.

• ELAC Argo B51 Wireless
• Gold Phantom
• doss speaker bluetooth - Cheapest for traveler like me.

Gold Phantom was the best I think in all and I can suggest if you're looking for a high quality sounds.
