Caiman passive output mod revealed

[Canetoad]

I've just received the 2.2uF Auricaps I ordered about a month ago. I'll be replacing the 1.6Uf Clarity caps currently in my Caiman with these on the weekend. Wonder if they'll sound any better?

On a similar note, my other amp has input impedance of 25K, so requires a higher capacitance. Can anybody suggest poly caps that would fit inside the Caiman that would be at least 4.7uF?

let us know how the Auricaps work out for you, Bernie. I love mine but give them a week of running-in.

I like it!

Certainly cleaner sounding now that the Hitano cap has gone and replaced by the big yellow 10uf. Sounds much more bouncy and alive so I suspect that the 2 No. 10,000uf caps were deadening things a bit.

I have just removed the 2 x 2200uF smoothing caps from my 7510 to make room for the 8uF Ansar SPA output caps as I've been running with the lid off for a few weeks. Despite not putting anything in place of the smoothing caps there has been a noticeable improvement in midrange clarity (and I can now get the lid on )

A few weeks ago I got around to installing Murta regs. It was a bit of a tortuous exercise, as I'd cut off the 12v reg's pins too close to the board and they were a pig and a half to get out , did the wire link replacement of R1. Anyway here's the pic.



As you can see I melted the line socket.

Nice one, Graham. If you decide to settle on those coupling caps you may want to desolder the multi-way socket and solder the caps in place as I have done. This keeps the muting relay in circuit.

... did the wire link replacement of R1.

Help, I'm getting lost in this thread ... Can you tell me what this wire link is or point me to the right post ... Thanks!

This is my Caiman with Obbligato Premium 15uF/250V (bypassed with Vishay MKP1837 0.1uF).
The new capacitor are huge, for this reason (+ a linear PSU) I make a new case for the dac.

It's the resistor behind the Murata 5V regulator. If you haven't fitted a Murata regulator then you have nothing to worry about.

...ah, thanks Stan. So much mods around here ...

Well, I've been listening to the 2.2 uF Auricaps in my Caiman and can say that I'm not sure if I like them more than the 1.6uF ClarityCaps. I agree that there is better bass weight and plenty of clarity across the board but they sound a bit too bright in my system. I'm thinking they may be exaggerating the harshness I sometimes here from the tweeters in my speakers. Maybe they need a bit more running in.

Overall, I think I'd probably stick with the ClarityCaps for the time being. Maybe the Auricaps will sound better after I've installed the Silmic II caps, Murata regulators and linear PSU. I've received the bits and pieces and hope to install them this weekend.

I'm also waiting on delivery of a Gator board so will be trying that as well when it arrives.
