How many capacitors do you need?
NuForce review page at 6moons (with pic on page).
 Since I am new at this, I am wondering what all these capacitors are doing for the sound of this integrated? Cheers - Mark |

 I have capacitors here that wouldn't fit inside that chassis (from what i can see) unless i crushed them  Also, SMPS (switchmode power supplys) tend to use much more modern caps that still have a low ESR (equivalent series resistance) & ESL (equivalent series inductance) & tend to be a lot smaller than stuff used at 100 or 120Hz which is the rectified frequency of normal mains depending on location & rectifier type. In simplistic terms it gives the amplifier a massive power supply which will certainly aid the production of quality audio. Power supply is expensive so when you see a hefty one you know the designer is going for quality (if they know what they are doing) rather than something mediocre. A small car engine can't respond as fast as a Ferrari engine, you want perfomance then make the engine more powerful (PSU).

Ok, so if this person is using these caps to filter out ripple from their PS, I am wondering if anyone has experimented with how many caps you can put after the bridge that will continue to improve the quality of the power?
Since I'm getting ready to try PSs for an amp (for my first time), I was curious as to what extent adding caps in series to an SMPS could improve it. Lot's of storage, but they don't look expensive. Cheers - Mark |

That's not a lot of caps.
How about 160x 820uF 63v Panasonic FC (32,800uF per rail).
