Given the age and original performance of these amps I would look at this as an opportunity to upgrade. I was familiar with Sonic Fontiers equipment around the turn of the millennium, I owned one of their CD players and one could do much better. I would have a look at CJ, Audio Research, and VAC amps.
Need to replace my Sonic Frontiers Power 3's
One of my Sonic Frontiers Power 3's just fried. I smelled something burning as it blew out. So, at this point, given their age (though I love them) I'm not sure it's worth putting a lot of money into them (curious what others think). If I were to replace them, I'm curious what people would recommend. I have Avalon speakers, and EAR cd player and a Conrad Johnson pre-amp. Any opinions/suggestions would be greatly appreciated.
