Mapman, I have the Micro walsh talls. my reciever is a yamaha RX-V465 that puts out 100 watts per ch. I know it's not the best reciever I could use, but to my old ears, it makes the ohms sound unbelievable. Like I said, I love these speakers so far, and don't want to blow them up. I plan to get a better amp and pre-amp in the future, but lack the funds to do so right now. I was forced to decide where I would put the most money on a limited budget, and I'm so glad I put more into the Ohms. If they sound this good with the Yamaha,I can only imagine what they would sound like with a good high current amp. I need more money...............sigh.....
