Guys, just a little note: The impedance of ML is where we have the most musical info safe for most any amplifier on these days. The lower impedance is only at very high frequency, over 18KHz, where there is not to much info in any cd format. Yes I know it is there, but I assure you this is not important. Better is quality watts instead quantity watts. Many of our beloved recordings, the mics that are used do not have a frequency response over 17KHz, and if it is not at the mic, who cares the 20KHz? I am not going to start a discussion here if we can listen 20KHz or not... just as an example, the FM broadcast for stereo signal has a 38KHz encoded signal, and the pilot light is on when the 19KHz frequency is present (Half of the 38kHz). There is a filter for broadcast that limits the frequency response not over 18KHz...and many of us are thrilled of the sound of some of our broadcast stations. Trust your ears, get the amp that you liked most. There are may options with the right budget for you there. Be patience, and it will be rewarded for sure... happy listening.
