Goertz MI2 and amp oscillation

I am auditioning some MI2 Veracity's and they sound fantastic, but I have read some mentions of amp oscillation with these cables due to the high capacitance. I am using an Electrocompaniet AW60 paired with some Sonus Faber Concertino Home's. How do I determine if my amp is stable enough for these cables, or what are the signs of problems?

I haven't noticed any difference at all - I've listened to them both ways they sound great.

The factory supplied Goertz networks are designed to come into play at 160 KHz. As you might guess, this is WAY out of our hearing range of what is supposedly 20 KHz. Since i only know of one speaker that actually could make it out to 100 KHz, i don't think that we have to worry about the results being audible. Shoot, many components and most sources are way down by the time they get to 100 KHz let alone 150+ KHz. In fact, some are specifically designed for very limited bandwidth. Sean

Just another note on goertz networks - use them! My amp was idleing last night and when I went downstairs to shut down I noticed it was fairly hot, like it is when I use it for an extended time or my Thiels put it to task. I checked connections and 1 of the networks had slipped off a binding post from moving the speaker. These are fantastic cables. However, it's hard to believe only 1% of all amps oscillate with these - I use a Classe and fortunately they are very stable and have a protection circuit.

Now you know why i stress the fact that people should use these Pops, even if they don't think that they need them. Out of curiosity, how do you have the networks connected to the speaker binding posts ?

What i've found to work well is to use the clamping action of the binding post on the cable's spades or the bare end of the wire. I then install the zobel's into the banana jacks courtesy of banana plugs that i've attached to them. They remain very stable this way and do not interfere with the "clamping action" or quality of connection between the posts and the speaker cables. One need not use "high grade" bananas for this purpose, just make sure that you have a good connection from the zobel to the banana plug and from the banana plug to the binding post jack.

Hope this helps some of you out. Sean

That's a good idea, as you know Thiel's binding post is on the bottom and is a hassle to hook up cables - Thanks.
