InfiniCaps or V cap upgrades for ARC LS7


Hello Guys,

Just want to get better sound out of my LS7.  Wondering between InfiniCaps and V caps which would you guys recommend for output coupling caps.  Don't know if it worth it since it is very old.

Regards,
Eddy

I think it won't reduce price of LS7 that is now more like vintage unit that sooner-later will need re-cap anyways. 
It may increase it's value if the label will say "serviced".
You have to consider that a pair of V-Cap TFTF 2.0 uF output coupling caps will set you back about $800. 
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
