Caiman Mods

@Stan: Would I be able to use those regs with the stock heatsinks? Also, what improvements have you heard after installing them?

[StanleyB]

The Murata ones do not need the heatsink, so those need removing. The Murata current consumption is less than the 7812 currently fitted in the Caiman.

I didn't listen long enough to take note of the improvements with just he regs. I updated the caps at the same time, so detailed info is not available. But the depth of the detail in the music is now even greater. I can hear the voices of singers bouncing off the studio walls when they they raise the voice. This is clearly distinguishable from normal echo or reverb delay that is sometimes added to a track n order to create a similar effect.

@Stan: I noticed a similar effect from my cap upgrades, I will tell you what I end up with when I am completely done. Where can I find the murata regs in the US?

Stan, Couple of quick things.
Firstly, just to confirm the Regulators you linked (these) are the ones that should be used in the Caiman only, yes?
Also, the replaced caps...I'd be interested in having a play with these.

You know how it is....Your perfectly happy with something until some says you can make it slightly better by performing modifications within your skill sets, and with little cost

You also need:
Mouser Part No: 580-7805SR-C
Manufacturer Part No: 7805SR-C

I'll pm you about the caps.

Just use silmic ii caps, they sound very similar to the blackgates, and much better than the stock caps.

Hi

I have ordered the Murata regulators to beef up the power supplies to the dac and amp. I wondered whether the cap upgrades would be worthwhile as I am not intending to use the headphone amp to drive my 701s, just the fixed lineout.

I hope to fit the Murata's after Christmas, but am interested if anyone tries the regulator upgrade independently of the cap upgrades....

You need four pieces for the line output, and another four for the headphone amp section. So the 30 piece offer would be more than enough.
If you are not into headphone listening, then you only need to mod the line output.

What are the remaining 2 caps for then, I count 10 in the picture?
