We will make this month a wonderful AC filter that is soooo easy, you will wonder why you haven't done it before. Similar filters cost much money but we will build one for about $50.00 or so.
Why filter or "purify" your AC? Ok..you have all your high end equipment and Morrow Audio cables (Bam...hey! its my newsletter!). Your equipment plugs in to your home AC outlet. All the music is produced by the help of this AC. Doesn't it make sense that, in a way, you are listening to this AC? Your equipment, to reproduce your music accurately, depends on this AC and the purity of it.
Your home AC carries noise, and allot of it! Crappy noise like appliances turning on and off, light dimmers, surges, and all the stuff that your neighbors are also producing, if you are tied into their grid...which most are.
So, you sit down to listen, and all this "stuff" is there too...riding along with the music!
Now for the fun part! What we will do is put a large choke (Hammond 193D) across the AC source. A choke is a transformer with only a primary, no secondary. Essentially it is a black iron thing with 2 wires coming out of it.
All you do is stick an AC plug on those two wires and plug it into the wall near your system. You will be amazed! Everything sounds more relaxed, like the music is flowing better.

AC plug: ACE Hardware, Lowe's or any other hardware store.
From the Listening Chair:
Yes...as I sit here typing this, listening to a vintage Fisher FM tuner, grooving with the music, I realize that I have been lazy. I did not get the January newsletter out on time! With Christmas and then New Years and all, I did not have the time. This is not to mention being swamped with cable orders. Everyone loves the cables soooo much! I think you all will understand and not feel offended or cancel your subscription by my titling this newsletter as the "January/ February" issue.
Putting that aside, let's discuss something that brings a shudder to the die-hard audiophile...Surround sound! Yes, I must confess, I sometimes turn on a rear pair of speakers that are hooked to a surround generator, set to "hall". Do not fear, the signal does not pass through the main system.
What it does to the music, is hard to explain, especially since it goes against the 2 channel holy grail. I set the rear level very low, not too much. I am not an echo freak. The soundstage expands and becomes more 3-D. Separation of instruments becomes greater. Everything is more "real" especially live recordings.
I think what it does is fool the brain into thinking it is in a larger space, helping the walls disappear.
Right now I am listening with two channels, and it sounds great. Whenever I want that little bit of more realism, or am listening to a live recording, I might switch on the rear. It's the music that matters.
If you have a surround sound generator and an extra set of speakers laying around, give them a try. You might be surprised. I have tried this with visitors to my listening room, and they too were supprised.
