I have been back after a long break with no additions to my HT but I am again getting the itch to upgrade. I currently have a Yamaha RXV2700 which has been an excellent piece for my HT but I was worried how it would work with a 4 ohm load. I did test my infinity's paired to make a 4 ohm load and I did not have any problems. After all this time I have proof that the RXV2700 can handel a 4 ohm load even though Yamaha never put any 4 ohm ratings on anything. It appears that "Into 4 ohms, the RX-V2700 was able to deliver continuous power levels at a
whopping 272wpc x 1 and 230wpc x 2 with less than 0.1% THD + N." This was take from the following article

Later Phil
