Modern Linestages

This is a general question about how complex and expensive some linestages have become. I'm looking to understand why? I can grasp that really good volume controls are complicated and that equally good switches are not inexpensive. I also have a general understanding of the importance of a high quality power supply, which again is not going to come cheap. I just don't comprehend how you get to a 50lbs. plus preamps that cost well over $20k. Is this level of complexity really needed or is it the equivalent of the spate of 500hp "sedans" for every day driving?

The perfect linestage can be imagined as simply a wire with gain. If you do not need gain a passive preamp will do. So, you ask what about matching impedances? Well a simple buffer can be used. Enter the First Watt B1, a passive volume control with buffer. The buffer makes the passive preamp more versatile because the impedance issue is handled by the buffer. Expensive? Not in the least and very good sounding. Here is Nelson Pass's thoughts:

Getting back to the wire with gain. That will be the B3 and that will be coming soon. If you have a look at the pdf above, note how simplistic his designs are. Well designed and great sounding line stages do not have to be complex or cost a fortune.
