Audio expansion means to expand the dynamic range of a signal. It is basically the opposite of audio compression. For example, if the ratio is 2:1 and the signal drops 3dB below the threshold, the signal level will be reduced to 6dB below the threshold. Music. In music, dynamic range describes the difference between the […]

Having heard a balanced power supply in my system at a AOS get together at mine, the upgrade to my system really made me realise what my next step was. It really was a no brainer. Balanced power suplies work and they work really well. I didn’t realise my mains was so bad and how […]
There is a fundamental difference between projects worked in parallel or in series yet both have their merits. In the former, multiple tasks and projects are tackled at the same time while with the latter, every step follows the next. Each of us operates at different levels with respect to how we handle projects. Some […]
Just dug out a pair, put them on and remembered that I quite like these, sort of LS3/5a sound with more guts. Pretty inefficient and seem to need a fairly powerful amp. Units are Audax 8″ with Bextrene cone and a KEFT27 in a reasonably compact cabinet. Anyone remember these speakers? opinions? MORE
I’m thinking about taking the plunge and going active but I’m not sure how I would connect the speakers to my amp. I use a Marantz Pearl Lite integrated, which has RCA outputs galore but no XLR sockets. Most active speakers seem to use XLR connections or TS sockets (whatever they are). How do I […]

I reckon that based on the serial numbers of my Briks they are late 70’s/early 80’s. Looking at the B139’s the rubber diaphram is a pale grey colour rather than black and it feels fairly firm to the touch – almost ‘dry’ if that makes sense? Now, I’m wondering if speakers degrade with age and […]

Debate: This is a great topic. Paul, could omni directional speakers compensate for expanding the sweet spot vs a conventional speaker? Not sure what the pros/cons are of these types of speakers. Paul replies … You might get a broader more diffuse sweet spot with omnis or the whole affair might become muddled. Hard to […]
One of the easier ways to get on the wrong path is to build an understanding based on piecing together little-understood terms. A good example of this problem might be explained in my earlier post about dynamic range. Relying only on the measured numbers to achieve a more dynamic recording can easily lead to the opposite. […]
A few years ago when we were researching the PS Audio PowerBase product I spent a few weeks digging into the sonic impacts of vibration control. What I discovered is how much of a difference a solid rack or other means of damping and controlling vibrations in our electronics makes. It’s a big deal. It’s […]
In any endeavor, rules, standards, and procedures are essential. They exist to help us wade through often complex tasks. Learning a new system or technique I find myself following carefully the rules that others have established. Once mastered it’s time to start questioning those rules. This approach certainly does not work for everyone. In fact, […]
The Computer Audiophile writes ….. Shortly after attending CES 2016, where MQA was a very hot topic, I realized that there was more speculation about MQA than available facts. Nonetheless, it seemed like everyone had an opinion about MQA. Most people had never heard the final output of the MQA process, an actual song or […]
Found on the forum names of speaker manufacturers unfamiliar to me that supposedly are using new technologies or designs and as a result are making big impressions on fellow goners. Would like to see a list of these young and not so young companies that otherwise fly under the radar because advertisement just too expensive […]
