Thiel Owners

unsound, no worries about the character drop! Thanks for passing on the info. about the Threshold amp. unfortunately, it just sold. There is another Threshold 300 amp that eBay sent me to, but they want $450 more and it looks older without any of the upgrades this unit had. I appreciate your feedback and I'm all ears about your reservations about the other amps mentioned.

tomthiel, thank you for your comments on the Threshold amp, it speaks volumes about it. 

@jthifi, It appears as though that auction closed without any bids. It might reappear for sale again.

unsound, Good catch, I missed that!

jthifi - Stasis was the or among the first Pass designs. Its sliding bias and resulting internal stability obviated the need for global feedback. It is very linear and musical and as mentioned, Thiel used the Stasis 400A (last 70s) as one of its development reference amps.
As time went on, Nelson's topologies became more and more simple, direct, minimalist and with very high quality components. In my opinion they rival the best in the world. The S-300 will not have that extreme finesse associated with later Pass designs. But at its bargain price it will out-do much of what's out there at any price.
