One of the biggest, most offensive, waste of sheet metal, plastic and steel SUV's on the road - a hybrid? What a joke!

The whole hybrid idea is IMO a total load of bunk, a stop gasp measure at best; really, just another example of the big guys cashing in on a trend, a buzz word..."Hybrid".

Here (on planet Earth) we have an enormous infrastructure built around the car - in particular, the internal combustion engine.
Now, as the supply of fossil fuels start to dwindle, "they" want to abandon the internal combustion engine in favour of electric motors and batteries...BATTERIES! Specifically, lately, lithium ion batteries. I know about rechargeable batteries - I've used them every day for the last 20 years. The technology has improved for sure but they still...

Hi all. Apparently, this is the first blog post of the new DIYAudio (unless the new software is fooling me).

Sooo...... What would someone like me want to blog about? All I can really do is post links to my threads and post pictures of my ideas. I don't really have enough to contribute which would warrant a regular blog...

One thing I think deserves mention is the thread below about the Allison output stage. Surely there are more interesting things to talk about, things more pertaining to audio (there is generally a sort of Zen approach where even though a circuit may measure well, there may be other ways of doing it that sound better).

The significance of the Allison, to me, is its measured performance as a voltage buffer. You still need a low source impedance because the input impedance...
