Nelson Pass First Watt amp F1

Well I guess that answers my question, not the amp for me. I guess I'll just stick with tubes, its working for me, my mind just runs crazy from time to time.

Hey Twl, from looking at this article it appears that a frequency shaping network is required to optimize the performance of a particular driver with this amp. If the ones you heard at the show did not have one (my guess is it did not) then that may have contributed to your unfavorable impressions. I've never heard this amp and probably never will but it is an interesting concept.

I dunno.

The guy told me that he got it from Nelson, and I would have expected that everything needed would have been with it.

The exhibit was from the maker of the speaker system, so I don't think that anything would have been left out internally, or externally, because he was making the stuff, and he sounded from his conversation to know Nelson Pass.

But, to answer your question directly, I don't know for sure if there was any network used or not.

Interesting design!

If it is a current source, rather than a voltage source, perhaps some Apogee users might find a good amplifier there. Maybe it won't melt like most amplifiers out there.

Conversely, most more "traditional" speakers might sound odd when paired with it.

How much does it cost???

It retails for $2500 there website is http://www.firstwatt.com
