I Recapped my Conrad Johnson PFR. Wow! Some of the best $$$ I've spent

Right. Of all the cost effective big bang for the buck things you can do caps are way up at the top of the list. Super easy too. The values are printed right on them. Anyone can simply look, order, swap. Hardest part is getting them to fit. Better caps almost always are bigger. Aside from that its a simple swap.

Another mind-blowing swap is better diodes. The power supply affects everything. Depending on the quality in there now newer better diodes may be just the thing. I did the ones in my tube amp and was flabbergasted what that $6 bought me!

My Oppo CD/DVD player was modded with all the caps replaced. Several hundred for the mods, more than the player cost, but the results speak for themselves. 

This all works because manufacturers have to build to a price point where the cost of every single part gets multiplied many times by the time it reaches retail. Please note: every single part. This includes shipping. Includes the box and all the packaging. Run the numbers, no wonder they are down to pennies for a cap. So you spend dollars, boom, instant massive improvement. Then go look at the prices of the components that use the quality level you put in there. They are $10k and up.

Modders rule!

Where are the manufacturers' fanboys today?  "No you shouldn't even open the cover yourself!"  "Only the manufacturer knows what's supposed to be done!"  "you are just altering the sound, that's heresy!"

millercarbon it would seem you are an expert at losing money. Wouldn't you rather buy more music?? I guess not.

Mijostyn seems you've never gone the mod route, it is hardly losing or wasting money unless you somehow equate greater musical performance and engagement a waste. Better sound promotes more musical purchases, at least in my experience. Well placed mods/upgrades by an experienced tech is some of the smartest spending you can do.

Replaced the caps in my Arcam Alpha 10 int. amp w/Kendeil's myself. A world of difference! $40. A lot of other little mods which cost very little and greatly improve the sound. Everything has an effect. If you have never done these things, you have no idea how much improvement there is to be made.
