Here's an unusually informative YouTube channel I stumbled upon.

This one is based mainly around the Beatles on vinyl and goes into considerable detail. 

I always wondered why the original albums sounded different to some of the recent reissues.

Well it's explained here on a video of the 2014 mono vinyl box set that the fashion back in the 1960s was to cut most records "loud and hot".

That way they would sound good on almost anything at normal volume levels.
The downside might be increased distortion at high volume listening levels.

Loudspeaker Isolation.

Here's an interesting article from IsoAcoustics inc looking at that thorny question of spikes versus lossy decoupling.

Despite reading like an advertisement for their own products they claim to have scientific data from research conducted at the NRC (National Research Council of Canada).

They even provide a link to download a White Paper in PDF form.

It's certainly an interesting read that might go some way towards explaining the differences between the isolation provided by spikes and more lossy decoupling methods.

Audiophile Turntable 101: Acoustic Research AR-XA TESTED

In case anyone has not seen this previously, here’s a hugely informative 50 minute YouTube video by M. Zillch to enjoy.

Perhaps the most informative of its kind.

Some of the fascinating demonstrations shown here are not advisable to try at home with a modern turntable. 

On the other hand they might make you think again about the so-called advances in turntable performance over these past 60 years.

Here's a couple of interesting YouTube clips courtesy of AsapSCIENCE.

Both have some good illustrations to demonstrate the sometimes strange relationship between sound and perception.

It's quite clear to me that our eyes can play a considerable part in the processing of what we hear.

Just why this happens is a little odd though. It's as if either our brain cannot resist feeding in extra information to 'help' with sound processing, or that it insists that visual information must take precedence over what we hear.

Here's yet another informative video from our friends at Audioholics.

How to Achieve Realism in Audio with Dr Edgar Choueiri.

The good Doctor's findings might surprise some of us here. Some of his comments certainly made me think.

Here he is with Matthew Poes and Don Dunn.
