Alpha Core Goertz......need recommendations


I am going to upgrade my speake cables. My system is the 20 yr old Infinity RS-1B's......I contacted UsedCables and they recommened Alpha Core cables because of the cost and quaility. I will be using short runs and will start with the base application.....(amp ((perreaux) to crossover and then crossover to base column). Then another (higher quality Alpha cable) for my mid/treble application (amp ((ARV VT100 mkll)) to mid/treble column.

Anyone have any experience and comments on these cables or any other recomendations??

Thanks all!!

I've owned RS-1B's (superb speaker, by the way...just too
big for my present room). I'm using Alpha-core Goertz
MI-2 speaker cables, and Tourmaline IC's to the power amp,
Goertz Sapphire in the system. I'm very pleased with the
Goertz cables, and have used MIT, Kimber and Monster in
previous systems. I think the Goertz are a tremendous value.
I have have great experience with the larger diameter Goertz cables, such as Sapphire Interconnects and AG2 speaker cables. The smaller interconnects are precise but less bass. The interconnects have high capacitance so use short runs only. Not sure about the speaker cables.
The Micropurl interconnects are not that high in capacitance even though the design looks somewhat similar to their speaker cable design. They took this into account when designing them. That is why they have the "extra" third conductor in them. The placement of this "dead" conductor increases inductance, bringing the cables much closer to what one would expect from "normal" interconnects. This also adds some versatility to these cables, as they can easily be converted from a two conductor RCA cable to a three conductor balanced cable.

Awdeeofyle, were you using impedance compensation networks with the Goertz when you ran them ? What you describe sounds like an amp on the edge of oscillation i.e. lack of clarity and focus. When an amp goes into oscillation, you see that type of "image" on a scope. While you can see the "correct" or "primary" image, it is floating in a haze of oscillation. It looks fuzzy, lacks detail and definition and is nowhere near as clean or pure as it should be. Once the oscillation is removed and stability restored to the circuit, the clarity and focus are back to what they should have been to begin with.

The reason that i said it sounded like your specific amp was on the edge of oscillation is that you would have smelled it cooking itself to death if it was in "hardcore" oscillation. The smell of "burnt electronics" is unmistakable. Due to differences in design and bandwidth, some amps are more stable than others. As such, some will self destruct while others will not flinch in the same exact situation.

The bottom line is system synergy and personal preference. Since we are the ones that have to live with and listen to our systems, we might as well make ourselves happy as best we can. Go with what you like, regardless of brand or cost. That is why i have several different brands of cables in several different systems. There is no one cable that is universally the "best" in my opinion. Sean
