i sent the raptors back. i listened to a recording of the tchaikovsky violin concerto on the chesky label. i compared the raptors to my vtl deluxe 120 in triode mode.

using the vtl the violin was more full bodied. i heard the strings and the wood body. wit the raptors, the balance favored the strings and the sound of the wood, was barely evident.

I have the PS Audio GCC250 driving Magnepan 1.6s.
They play well together and have stunning dynamics.
Ruthless exposure of mediocre source means I ended up having to do a pretty substantial upgrade there, as well.
Now that's over, I wouldn't change a thing.

any idea why they need to run for a while after travel? Not that I doubt it, just that I dont understand it. And you would think that the rep who sent them to me would want to show them in the best light and tell me to wait a week. But that wouldnt be the first time that a vendor said a component would sound optimal right out of the box either...
strange hobby.

Outlier, I will really be looking forward to hearing how the Spectron matches up with the MBL's.

Is the Spectron brand new? If so, I can tell you from personal experience that the first 100-150 hundred hours of a new Spectron can be cruel to your ears. Do not play too loud or you will really strain your ears. After 100-150 hours the sound starts to smooth out with continuing and notable improvement as you pass each 100 hour mark with close to full break-in at about 1000 hours. To expedite break-in try keeping a source continually playing through the speakers 24/7 even at low volumes. Good luck and have fun.

Jimmy3993, I can only guess that mechanical vibrations, temperature excursions, and who knows what else may have a detrimental effect. . . besides you have no idea about their past history. . . so, assume the devices are almost new and start break in from the ground up.
