Cap voltage


I took the lid off of my preamp today (Cary SLP 98) to poke around in advance of an impending cap upgrade. I was told by the tech that I can co to a smaller value on the output coupling cap ( might increase dynamics if feeding a high impedance load) but need to stay with 600v. ??? Why 600v when the pre only puts out about 2v. Don't smaller voltages sound better?

2 Vac signal...
What is the DC power supply voltage applied to the plate of the output tubes? The caps block the DC voltage from the power amp's inputs.
I feel real stupid right now. The DC offset is about 450v
But what about value? Is a little smaller better?
The more voltage tolerance, the better. Too close and the cap will overheat and may blow. Heat is the enemy of the cap and you need a little padding. 800v is better than 600, etc. The REL and Jantzen along with the Mundhorf offer good voltage tolerance and great sonics. My fave is the v-caps. Not for those looking to spend 20.00 for 4 caps, but worth every penny. jallen
You need to keep the voltage at least as high or higher,but smaller uf/mfd value may loose some bass in my experience.That might make highs appear to sound better.
Considering Mundorf silver in oil over V cap tftf. Maybe they will give me a little more wooden second order distortion: not so "perfect" I'll stick with stock values and ratings. Thanks all! And may powdered sugar fall gently upon your ears this evening.
