Lot's of heatsink surface....  :-) ...and two dozen transistors sharing the load... :-) |

I have been running my XPA-1's constantly since 8AM this morning, listening and listening and listening to a very eclectic selection of music, ranging from Glenn Alexander's haunting guitar whispering "the Belle Mahone" to Sade's bass shaking "Love Is Found" and everything in between, even a bit of "Death Magnetic" by Metallica. Initially I turned them on to do a Sumiko "Master Set" to finish off my speaker placement but after an hour or so of tweaking the placement, I was done so I just settled in to listen...and have been listening ever since, making the little blue LED's spill across the face of the units like small blue waves attacking a black sand beach. They are barely warm! I know a class A/B amp is a bit more efficient with it's transistors operating symmetrically with a little voltage always present on both sides of the positive and negative power rails but I expected that over time, and given the slightly abusive levels of listening I've been doing today, that they would at least be warm to hot. Not so! Dang I love my XPA-1's!!! |

Barely warm running Magnepan 1.7s running at moderate volume all day long. Probably would have been fine with XPA-100s afterall...

I'm enjoying it...but may need to tweak the Maggie's as they may be a bit bright for my taste for my room. Or DC-1 and XPA-1s too bright?
May need to put in attentuators...or use spacers to tilt back?

May need to put in attentuators...or use spacers to tilt back? I run the DC-1 directly into XPA-1's and Maggie 1.7's. I use the spacers; not too bright at all. Detailed? in spades. Don't toe in more than about 10 degrees, adjust spacing between them if necessary. |
