It may sound funny, the headline of this post. I love the sound of tubes, have owned tons of tube equipment and yet – I have never designed a tube piece ever. And add to that mystery the fact that […]
How boring if you’re biased right in the middle eh? You don’t lean to the left or the right, you’re just middle of the road for everything – as if you don’t actually have an opinion. Well, in audio amplifier […]
If you’ve managed to wade through this series of posts on tubes vs. transistors you’d know that while there are indeed fundamental differences between tubes and transistors that by themselves have a major impact on the sound of equipment using […]
No doubt you’ve heard terms like class A, push pull, , SET, full complimentary, single ended etc. These terms all refer to how we use an amplification device rather than the amplification device itself (like a tube or transistor). Many of […]
