InfiniCaps or V cap upgrades for ARC LS7

Thank you everyone for your suggestions.  

gs5556,
If it is V-cap I was looking at V-Cap Film Capacitor 2uf / 250VDC, OIMP Series, 5% tolerance, 0.67" D x 1.7" L.  It is about $50 each.

Save your money for the dac upgrade, then the room treatments, and when your wife will allow, the speaker upgrade. Then revisit the preamp. Take a breath, Eddy! haha Cheers,
Spencer

Okay, will do that Spencer. :)

Hi eddy,
Replacing the coupling caps can make a very noticeable different (agree with Dave of Clarity caps) and the V cap OIMP you're considering are very worthwhile upgrades. The cost of those caps represent good value. I'd do this upgrade if I were you. I used these  caps in a Quicksilver preamplifier(replaced original MIT caps)  in the past with a very fine outcome.
Charles,

Thank you very Charles.
