FYI: Goertz Zobel Networks


I just got off the phone with Goertz, and they mentioned that the Zobel Networks can be installed at either the speaker binding posts, or the amplifier binding posts.

I thought I'd pass this information on, as I've seen others mention difficulty getting a tight connection on the spades, while also adding the Zobels. This is my case with the Vandersteen 3A, with small screw terminals.

If I had binding posts, I could just solder bananas to the Zobels and install that way, but now I was told that I will be able to do that on the amplifier end.

Non-polarized capacitors are polarized, so you can orient them one way and get one sound / reading and flip them around and get different sound / readings.

As to mounting the zobel's at the amp or speaker, at the speaker is always the preferred method. Some amps have built in zobels right at the binding posts inside the amp.

As for using spades, bananas, etc... I've found that it is very convenient to connect the speaker wires with spades for the tightest connection and to use decent quality bananas for the zobels. Each allows a solid connection without interfering with the other. Obviously, one would have to have "5 way binding posts" on the speaker to take advantage of such a method. Sean

Audioengr: I shouldn't have phrased that the way that i did. Let me say that non-polarized capacitors have a specific orientation to them and each orientation will have a sound of its' own. The key is to find which orientation sounds best to you in that specific circuit and then to install all of the capacitors in the circuit(s) with that same "polarity" or orientation. Mixing the orientation of caps from channel to channel or within the the same channel will result in a less consistent presentation with increased "haze" or "fuzz". When trying to orient non-polarized caps, one can't "ass-u-me" that the printing / orientation is the same from cap to cap, so each cap must be checked individually. Sean
