Mark Grant developed a special short length coax and RCA/PHONO lead for me for use with the Caiman II. He spent quite some time getting it right, and it is the best set of leads I got for the Caiman. Each lead was hand made for utmost accuracy and performance.
He was supposed to put it on his website so that others could try it out as well, but I don't know if he did or not. So check his site or give him a call. He did mention that it would be cheaper to buy as well compared to a 1m lead.

Does anybody have the upgraded firmware installation instructions that they could send me please?
I fancy trying the new firmware, but I can't find the instructions anywhere.

I use 1m of Stan's optical cable and it sounds better than co-ax to my ears, although not a big difference.

Open lid Carefully remove firmware chip noting direction (semi-circular cutout indicating pin 1) Replace with new firmware chip making sure every leg is engaged in its hole and the chip is the right way round Close lid Enjoy! |

Thanks.
Job done. Now to play with the firmware.

Sorry to Stan for my massive delay in writing this review of the latest firmware. I got the chip about a month ago but jus haven't had the opportunity to install and listen it until today. First off, the bass has again tightened up, but without affecting the performance or depth, there seems to be more speed and overall control. The sound has also warned up (and this is just after installation, so as we all know should improve), overall a cleaner, clearer presentation with bags of detail and the vocal are sweater. Bloody excellent update, thanks once again Stan  |

Is it my ears, or does this upgrade start to sound a bit better over time?

I noticed that each CPU/firmware upgrade took a little while to settle in.

No, I don't subscribe to that theory. Too often I make a change and don't hear a difference over time. When I do hear a settling-in difference, it becomes obvious to me. It can easily be possible as the circuit isn't just digital, it involves analogue components that can change depending on how the music is being processed, how the data is clocked etc.

I have often wondered whether some components like caps are subject to some kind of memory effect, which eventually shifts over a period of time when a different piece of equipment is inserted in the signal path. |

I'll have to let you know but I found that when I upgraded the firmware last time it took a little while to bed in… so I suspect the same with this latest one.
Personally I find with all equipment that there is an audible difference after a period but especially with digital sources for whatever reason.

Speakers and cans have mechanical parts which loosen up after some time. Caps may form as well after some time - academic discussion though, the rest is rather a myth. |

It is not clear or obvious what you refer to. |

It is not clear or obvious what you refer to. Yes of course if misunderstood. In my humble opinion, the myth is the fact that certain components change the equipment sound after some time of burn in, especially electronic components - ok, maybe as I said some elements like caps could form after some time, resistors and other elements adopt to the environment temperature (changing thermal noise etc), but how much those things are related to what we really hear or what is the actual mental bias, that's not clear (only A/B tests could help, but in this case it's also difficult some time). It also apply to the snake oil about speaker cables, interconnects etc. Another story are mechanical elements - these of course change the subtle part of the result of the equipment's sound - headphones or speakers for instance. In case of IC's like the firmware PIC, I don't believe it could change after time - it's EEPROM with the C-compiled code - nothing else. This phenomenas are quite interesting and I noticed that to hear the difference you need to get used to one equipment and after it change to another one you'll notice the difference, but only difference and judging if it's better or worse it's not so obvious - sometimes you'll change your mind several times, stepping back and forth. That's my opinion. |

As I cycle through CDs here I can probably let you know. Will be a few days/weeks

Posted on AoS forum as well, but anyone know what are the inner/outer diameters of the power jack for CMII? It seems that the jack from Anker Astro Pro 2nd Gen is liitle bit loose - different inner dia, so probably would be nice to get kind of adapter to improve the connection. Anyone?

I'll have to take a look later, Krzysztof.
