Goertz MI2 and amp oscillation

I am not that familiar with McCormack products although i have a lot of respect for what i've seen in terms of design.

As to the MI-3's, these sound different to me than the MI-2's. You will have to try them in your system and see if you like them. Personally, i like the MI-2's a little better. The 3's are a little more bottom heavy to me, which does not compliment my already "weighty" sounding speakers. However, given that you are running Thiel's, which many find to be somewhat bright, this might work perfectly for you. Either way, if you don't like the 3's, give the 2's a try. If you don't like the 3's nor the 2's, you don't like Goertz products then. : )

Good luck and i hope they work well for you : ) Sean

They shut my classe ca200 off out of the blue - I say that because it ran for weeks with no trouble and I switched out some cables and when I put the goertz back in I forgot to put in the rc link and one day it shut down the amp - have since reinstalled and no problem...

Pops, you are lucky. Several of my amps have no protection circuitry in them by design. If i forget to attach the zobel networks, up in smoke they'll go. I caught one screw-up as i could literally smell the amp "cooking". This was only after about 1/2 an hour or so of idling after being connected and powered up. Would have been an expensive "oversight" if i had left the house for a bit or something else came up. That is why i try to stress the importance of using the Zobel's if unsure. As in your case, you might not have tell-tale signs instantly, but that doesn't mean that the amplifier likes it long term. Better to be safe than sorry. Sean

Has anyone noticed ANY change in sound quality using the Zobel jumpers? It just seems like it must affect the sound to some degree.

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