Linear Audio 2
Linear Audio Vol 2 is the third issue of a series of printed bookzines dedicated to technical audio and perception. The international team of authors for this issue again offers technical audio articles, discussing concepts and ideas as well as offering construction articles on a wide ranging number of subjects, from the State of Digital Audio to tube and solid state amplification projects to book reviews.
Gary Galo offers his well-considered views on the state of digital audio in: Digital Audio: Progress, Stagnation and Regression.
Tube Power amplification:
Rudolf Moers explains all there is to know about the Ultra-Linear Power Amplifier in his Adventure between Triode and Pentode, while Bob Cordell shows he’s equally well versed in tubes as he is in solid state with the very high quality The C70 KT-88 Vacuum Tube Stereo Amplifier.
Solid State Power Amplification:
Look, Ma, No Distortion! Kendall Castor-Perry exclaims when showing his new Class i output stage, while Samuel Groner presents a A New Amplifier Topology with Push-Pull Transimpedance Stage.
Marcel van de Gevel offers some effective Simple Loudspeaker Correction Filters, while EUVL increases accuracy and simplicity at the same time with his Zen -> Cen -> Sen – Evolution of a Minimalistic IV Conversion Circuit. Nelson Pass is back with an article where his Arch Nemesis gets a SIT transplant in SIT! Nemesis.
Stuart Yaniger bravely opens Pandora’s Box and explains why we should do controlled listening, and how it can be done, in Testing, One, Two, Three.
Kendall Castor-Perry reviews Douglas Self’s latest tome The Design of Active Crossovers, and likes what he reads. Guido Tent reviews Rudolf Moers’ first book Fundamental Amplifier Techniques with Electron Tubes and gives it a prominent place in his library.
