Goertz MI2 with Sim I-5

This is not true. Some amps / circuits can become marginally unstable yet not break into full blown oscillation. Performance is degraded and the circuit will VERY gradually break down. Full blown oscillation causes much more obvious degradation and would result in a much quicker death.

As to the sound of the system, what kind of results are you getting on other recordings ? Try some male and/or female vocals accompanied by an acoustic based band, some piano recordings, etc... Mix it up as much as possible. I would not base my opinion of a component or cable on one "strange" or "different" result. Sean

If your amp is running noticeably warmer, you do need the zobels. I would refrain from running the amp with the Goertz until you can install the appropriate impedance networks to take care of this problem. In the meantime, go back to using your older cables and see how they compare now that you've gotten used to the Goertz somewhat. This is not to say that you've heard your system with the Goertz running at optimum performance as of yet though.

The zobel's should be available from the dealer that you purchased them from ( if you bought new ) or directly from Goertz at a very nominal charge if you bought used.

As to the "echo's" that you're hearing, it is possible that you are now hearing the reverb that was originally added to the recording. This is VERY common, as it helps to fill out a voice and add "body" ( if properly used ) while somewhat helping to cover flaws in the vocal performance.

From your comments, it seems as if you've got more apparent volume with the Goertz than what you previously had with another cable. Am i reading that correctly ? Sean

My guess is that the sound filled out with the Goertz, giving it more apparent weight and impact and apparent volume. It is possible that your amp is actually loading up slightly better, but i doubt if it would be enough to make a huge difference. Sean

Glad to hear it. Hope you like the cables. Keep in mind that if they have the factory terminated silver spades on them, you will need to clean them once in a while. They do oxidize, but silver oxide is conductive. Not a big deal, but something to check out once in a while. Sean

Yes, you will need the zobels with the Perreaux or it will cook itself to death. Good luck and please respond back with your results. I'd be curious to see which you like better. Sean
