Same for me on this one. There is so much music available, in so many  ways, that no need to listen to anything that is badly recorded. Thanks goodness!!

Quality vs. content

I don’t listen to many bad recordings, even if the musical content’s great.

It was once a quality vs. content issue because bad recordings were made worse while good recordings were made better. Over the years, and as equipment has gotten better, that’s no longer the case. Today, all types of recording qualities play nice on the audio system, yet, I still focus on the better recordings even at the expense of musical content.

Why?

Because of time.

I don’t get as much listening time as I would like. Life just gets in the way. And for me, what time I do spend enjoying the stereo is time I want to maximize.

Am I greedy? You bet. Greedy that I want great quality and great quality.

With so much good music today we don’t have to settle for second or third best.

4-channel audio

There’s a lot of information in a stereo recording that some systems don’t reproduce well. In fact, most systems keep the room cues and ambiance locked away in our recordings.

One way to unlock them is by careful 2-channel setup and the very best electronics. Like what we’ve done in Music Room Two with our BHK electronics and IRSV speakers. That system has spatial cues that often times surround the listener in uncanny ways.

Yet, few of us have an IRSV and a complete BHK stack. Is there a way to get more of what’s locked away in our recordings with what we have? David Hafler certainly thought so.

In the 1970s, audio designer David Hafler experimented with what has since become known as The Hafler Circuit. In it, 4 speakers are employed rather than just two. The extra pair of speakers are in the rear of the listening room and provide a sense of space that few systems can come close to duplicating today. And the Hafler Circuit required no extra electronics.

If you want to experiment, dig out that old pair of bookshelf speakers that might be gathering dust in a bedroom or closet. Position them the same distance apart as the front speaker, but behind the listener. Then, run another set of speaker cables to the rears. Connect only the + lead from each channel to the + input on each rear speaker. Using a single speaker cable lead, tie the two – terminals of the rear speakers together.

Voila! Surround sound from 2-channel.

This scheme actually works and takes advantage of the fact that in a live performance, the distance between the audience and the performers is great enough that there’s a phase difference between them. Thus, the audience is out of phase with the performers and that difference is played on the rear speakers. When you play studio recordings there’s always enough phase differences to light up the rears and you get a sense of surround sound.

It’s more of a fun project than anything I recommend, but that’s what we’re here for.
