Nelson Pass First Watt amp F1


Any experience with this amp? I am VERY seriously considering getting one, but would like some feedback from the folks at the 'gon first.

This is a very specialized amp that boasts an 80 ohm output impedance. In effect, the amp is designed to be "loaded down" by the loudspeakers, which results in a shifted tonal balance. This shift in tonal balance helps to compensate for the lack of low frequency weight found in many "full range" aka Lowther, Fostex, etc... type drivers. If used in conjunction with more conventional multi-way loudspeaker designs, it probably won't sound too good. On top of that, and as Herman pointed out in another thread, the crossover points on the loudspeaker will be altered. Due to the fact that this amp acts like a current source rather than the more conventional and commonly used voltage source designs, it will have very limited mareketability and would be "near useless" for most audiophile type speakers.
