InfiniCaps in Audio Research gear

Who out there has tried InfiniCaps in older ARC designs or had ARC mod your unit with these caps . I am just wondering what others have felt about the results. I have an SP9, which was discontinued before InfiniCaps were used by ARC. I am very pleased myself with the results after swithching out several WonderCaps for the InfiniCaps. Anyone else try this. What did you think when you were done? What unit did you try it with?
My next step is to attempt to put an IEC connector on it and plug in a better power cord.

Audioman4,
Can you give me a list of the InfiniCap values and voltages in your LS7, if I remember right there are only 4 of them on the board. A friend of mine has an LS7 and is interested in trying the InfiniCaps in his. Thanks for the reply.

Re: Steve Huntley...... he is the type of person who likes to talk with his potential customers.
Give him a call. He will be more than happy to discuss his work and how it can improve your specific unit.

Maxgain,
First was the power supply and an iec connection. The power supply mod took away what I thought was the brightness with the sp9 while leaving the incredible detail. I know caps were replaced and I am not sure where. Steve could give you all this info. I only use the phono section of the preamp and I know he did some mods in that area and finally he did the attenuator. That made a huge difference with the openess and three dimentionality. MOre air also. As far as cost I suggest that you talk to Steve about that as I did this work piece meal, cost me shipping up the ----- but that is the way it is. Steve is a great guy to deal with and the results are worth every penny. Oh the very last thing I did was to put 7308 tubes , nos Siemens and Steve set the voltage to match the tubes. Good choice of tubes.
Hope this helps and I strongly suggest that you talk to Steve if you have a serious interest in mods to your SP9.

I finnaly got around to putting an iec on my 9 today. What a nerve wracking procedure. Cutting strange holes in the back of your gear can give you sweaty palms. I did some initial listening with a better cord(I used the cord from my CD player and listened to the turntable) and I think the results are going to be real good.
Thanks for your responces!

The Infiniti caps are very good, but you might find you can get more out of the ARC unit by rewiring the signal paths as well as I did years ago with some ARC units. The new caps will likely be smoother and you can go with internal wiring that will allow more information through as well....
