    Since you can count the number of Spectral dealers on the fingers of one hand, it seems foolish to me that there is any distinction between a dealer and a 'select" dealer. Is there really?

    In the US, yes, it's silly, there is only two that carry the 500s. But there are another ~100 more around the world. It's sort of a reward to the best dealers. Nonetheless, I don't care for such business practices in high end audio, or other sh*t like one Pass dealer owning most of the US market, etc.

    Pass has a unique approach. You can’t compare them to other brick and mortar dealerships. They are not direct to consumer but they’re not conventional dealership model either. The consumer happens to be very well served by the Pass model in my opinion. I would not compare Pass Labs to Spectral when I comes to marketing approach and other services. For instance almost all models are always available with in-home trials.

    I think Pass has a sick sales model

    Warming up

    Fascinating amplifiers, claimed to measure better than the 30SV preamp, including distortion... quite impressive... more to come

    ack, two questions about the DMA 500, from your pictures. There appears to be a spacer under the knurled aluminum foot that the amp rests on, is this a compliant material? The wiring harness that connects the output stage to the speaker binding posts looks like the one used prior to the RS series amps, not the massive black ones they had, any explanation on this? I am looking forward to hearing these new amps, not sure where though now that Overture isn't a player. Thanks for your posting!

    Yes it's Sorbothane. I will be adding a layer of Isodamp when I get off my butt one day

    No idea; I can only guess that it's part of the overall capacitance and inductance of the circuit, possibly in conjunction with the speaker cables. There is no technical bulletin either for us to to be able to tell anything on this. I can also tell you that I briefly replaced the MIT speaker cables with some thin hook-up wire I have, in a test to make sure I didn't blow the speaker cables (see my system's thread discussion on this), and the amp ended up sounding literally like a 1960's hand-held transistor radio - no kidding.

    FWIW, I've been and will continue to be writing my impressions on these amps under my system thread, starting at http://www.whatsbestforum.com/showth...l=1#post512724
