WHY? If we cannot hear above 20kHz why do engineers insist on building amplifiers with ever higher bandwidths?

While I can’t tell you why designers other than our own like to extend amplifier bandwidth into the ultrasonic regions I can explain why we do. It’s called the Rule of 10. The rule of 10 is a lofty engineering goal that simply states we should strive to build products with 10 times the required […]

ROOM TEMPERATURE: To what extent does it affect a systems’ performance?

“The question reflects my ears telling me that my little ol’ hi fi sounds more dynamic, detailed and with more accessible low level information when the sun is shining ie at average room temps. around 20-25c. Could this be the drivers wobbling more freely when warmer?. Or is it the feelgood factor?” MORE

REALLY: Is there really an audible difference before and after recap/restoration?

I’ve seen this question posed several times. I just purchased my first completely recapped/refurbed amp/receiver. It’s a Pioneer SX-939. I can truthfully say I’ve never heard anything better. Period. Matched with my KLH Model 23’s the music just came alive in a way that I can’t explain and have never heard before. The soundstage was […]

VALVES / TUBES: This is the reason most tube power amplifiers have large output transformers and transistor amplifiers do not

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 us have also heard that tubes produce a warmer sound due to the fact […]

THE MAINS: If you can’t get it out of the wall in pure, unrestricted, undistorted form, uncompromised music can’t reach your speakers.

AC power is a complicated subject if quality is to be considered. The number of problems needing attention includes regulation, removal of noise, guarding against surges and spikes, lowering of impedance, isolation, restoring missing energy, attaining the correct level, uncontaminated grounds, ensuring there is enough current (both dynamic and steady state) for the job. What […]

ACOUSTICS RESEARCH CENTRE: Psychoacoustics aimed at solving practical problems. The results of our research are used in …..

The goal of psychoacoustics is to understand how people perceive and experience sound. This can be at a low level; for example, we might want to understand how accurately you can locate a sound source, or we might want to measure the smallest change in sound level you can detect. We can also work at […]
