After doing a lot of research on the subject these amps are very powerful in terms of wattage, in a way more so then the 200 watts would suggest. They have huge power supplies and put out a ton of voltage, however they have less than ideal amounts of current. I have two specs for the amp. Pass lists it having only 12 amps of current in their manual, however the less powerful aleph 1s had 50 amps of current, a big difference indeed. This difference can be largely attributed to the three vs. two gain stage designs. However the difference seems to great. A store however lists them as having 40 amps of current. I am not sure which numbers to believe. I personally think that it has 12 amps of continuous current but can peak at 40 amps. If this is the case it should be ok but not ideal for the speakers. Lastly, these amps do everything well except for bass slam and are not very dynamic sounding. Hence when they show these charachteristics with the Talons i think that is simply them sounding how they always sound. I agree that these may not an ideal match however. Lastly i was talking with the president of Talon, Mike Farnsworth, and he often powers them with 7 watt SETs to great success in a very large room. So i think that the amps would be capable of driving the speakers to very loud volumes but will not make them boogie as other amps could. Still the Talons have such great bass and slam it may not be the worst place to have a tradeoff. And yes the Peregrine uses the same dual 10 inch woofers of the Khorus. Lastly the impedence is very easy and stable. It is 8 ohms on average and never goes below 6.5. After all of my research i think these amps would be a good but maybe not ideal combonation. Feel free to comment on it. And oh yeah there is a guy here on audiogon who powers his Khorus speakers with Aleph 2s and loves the combination. So many oppinions!!!!
