The Vacuum State CookBooks

Allen Wright, the founder and managing director of Vacuum State is also
the author of two very well received books:

"The TubePreamp CookBook" and "The SuperCables CookBook".

Both of them allow you a deeper insight into his thinking and philosophy, but they also allow you to improve your own Hifi system to increasing sound quality with sometimes quite easily applicable methods, which lead to often stunning good results.

Allen's intuitive grasp of the subject allows him to explain in everyday language, rather than try to make arguments look impressive with reams of unnecessary mathematics or obstruse gobbledegook. However, this book could cause a few problems for both those "new to electronics", as well as boys from the old school
as Maxwell Smart would say: "Sorry about that!"].

This is the only book I know of which dares to take audio design into a more metaphysical plane. Most like-minded thinkers either keep their knowledge secret or are too afraid of criticism to voice their opinions. There are plenty of cranks about spewing pseudo-science, but here the information presented here is derived from solid reasoning and experimentation, albeit with a modest sprinkling of fairy dust
it's called humour].

I thoroughly recommend this book to anyone interested in either modifying or building valve equipment. It's a worthwhile addition to any library on the black art of valve audio.

"...a valve polemic calculated to annoy transistor heads...above all it's fun, informative and eminently digestible"
