  1. Hi all again, Here are some photos of the progress of Mac Fanless CAPS. Already have mounted the hard drive permanently. Linear power supply 5v 1Amp for the hard drive. Relay, which is activated by logic board for on off sources of linear feed usb card and hard disk. I'm still doing sound checks, sounds delicious !!! ;-) Now I'll start with optimization for Mac OS X. Audio Remove monitor, keyboard and mouse, put the lid on the box and Streacom ..... Enjoy the music .... !!!!
  2. Hello Tranz, You see I took your advice on the idea of going the way of power supply quality and feed independently disk. Now I realize that the way forward is pcie usb-alone card, PPP Studio and JCAT NEC chip card use, such as D-Link, I imagine that the installation of these is possible by adding the generic driver kext. Maybe later I try, although I put the improvement has been very good. The oscillator is: Vanguard Ultra precision Golden Oscillator, The Best TCXO, 0.1ppm 24.000MHz | eBay No recloking, the original D-Link oscillator is 24.000MHz, and also vanguard. The Orico was 12.000MHz oscillator, maybe that's why it never worked. Thanks for your comments. Lechu.
  3. For sound to tell you that there is a clear improvement, if not due to changes in the Card, the use of a separate usb bus, new power supplies, I imagine it will be around in general. But the sound is much better than before, there is a clear increase in serious, they are more tight, but very detailed sound is more organic, more relaxed, more analog, seems more condensed. I love the improvement! There is still a separate install the power supply for the SSD, the OS is optimized for audio, insulated with sheet aluminum macbook, usb card and power supplies. Remains to be done, but I think I will not get such a large and as clear as I've gotten now improving. I hope to have time this coming weekend to install the relay that will allow automating the on and off the auxiliary power (usb and ssd) and I'll be telling ... Greetings !!!
  4. Doing a search I found that someone has made a generic kext for USB 3.0 on Mac OS X. Os you can download it from here: GenericUSBXHCI USB 3.0 driver for OS X with source - Other Peripheral Devices - InsanelyMac Forum Although my original idea was that it was not necessary to add any kext the system, I wanted to give it a try. Simply install this kext for the card to be recognized, I used Kext Utility, simply drag and ready. I thought, it's not so serious, you also have to make a small modification if we want a SSD TRIM enabled nthat you are not from Apple. Here you have a screenshot where you can see that the card appears as a USB 3.0 bus, which is totally independent from the usb bus and the macbook recognizes the usb-spdif converter that is connected. While it is plugged into the USB 3.0 bus runs at 2.0 speed, I think it is normal when connected a USB 2.0 (Audiophilleo) device.
  5. I know I have another pci-usb card at home, but this is based on NEC chip and is not natively recognized by Mac OS X, once I made it work but had to add kext third. After modifying the Orico card and not make it work, I thought, I'll try again ... The card is a D-Link, namely this: The only change has been modified condensers Elma same capacity and replace the oscillator already had on the previous card. Here you have a picture of the card and mounted on the server.
  6. As I put in a previous post, I bought a pci-e card USB 3.0 to modify poniendole greater precision oscillator and see if I could make it work. I bought a Orico card, which is recognized by OS X natively Maverics change and changing the capacitors for a higher quality (Elma) and oscillator for Vanguard. It is important to say that I am not technical and it is the first time I do something about this ... This card tried it before modifying it, was detected by the system and could connect the USB-SPDIF converter Audiophilleo and fully working. Once modified, I got the system to detect but I could not make it work, which put me off a little ...
  7. I've made ​​a new linear power. After much research I bought the components and decided that the power supply would be based on the LM1084 integrated, offering up to 5 Amps and gives some good values ​​for noise and ripple. The power supply for the board is regulated to 15 volts and 4.5 amps gives. The fuene supply for the USB card is regulated to 5 volts and 1.66 amperes gives. and the power supply for the SSD giving a 5 volt and 1 amp, and I have made ​​but even it is not mounted on the server.
  8. Hi all, I have had a lot of work and I could not devote much time to this. I'm counting my progress with the audio server: I have increased the RAM to the server I put two modules of 4GB, the computer recognizes the 8gb.
  9. Hello Tranz, You can check if the heat pipe is broken as follows. Insert one end of the heat pipe in a bowl of hot water and hand holding the other end of the heat pipe, if you perceive clearly that the end is in your hand is hot, the heat pipe, though bent, is doing its function properly heat transmission.
  10. Thanks for your comments wappinghigh. I keep sending photos and reviews of progress.
  11. Hello Harpy, I can not help you too, would look when characteristics, frequency and voltage (usually 5v) Sunny and compare with the Vanguard. For little money and a little patience with the soldering iron you can do the test. Decide your ears! regards
  12. After several emails to ppa studio, asking if you can modify a mac usb card, no response, I decided to modify a usb mac same card. The idea is to change the capacitors for other high quality watch and replace the card. From what I have read in some forum, it is 80% of the improvement. usb pcie card Amazon.com: [Compatible with both Windows and Mac] ORICO PFU3-2P Lightning Mac USB 3.0 2 Port PCI Express Host Controller Adapter Card for Mac 10.7 10.8 and 10.9 or Later and Windows 8 with Low - Profile PCI Slot Cover included: Computers & Accessori oscillator Vanguard TCXO 0.1ppm 24.000MHz Ultra precision Golden Oscillator | eBay scheme for mounting the oscillator I have already asked everything you need, I will keep you posted on how the experiment ...
  13. hello! I think fanless mac is a clear improvement in sound, even greater than the change in standard hard drive to solid state disk. We have an electric motor that spins at a variable rate and that induces noise, not to mention changes in fan power. SOTM fan has a filter, a series of capacitors and resistors, which filter the flow and causes the fan load variations are less pronounced. SOtM In-Line Fan Power Noise Filter: Not only a good theoretical advantage to my ears, is a clear improvement. regards
  14. Hello Tranz, Work has me busy and so I have taken so long to respond. I used the original macbook heat sink, removing the heat pipe and the heat pipe sticking out of the box streacom instead. To experience, buy the heat sink of your mac mini on ebay and on that work to adapt a new tube for a heat sink, if something fails, you can always put your heat sink shirt. Give a little scared to do it but it's easier than it looks ... For now continue with the installation of the server, I have expanded the ram to 8gb, I installed audiophilleo2, and the sound is very good and detailed, but I think I can improve, I will change the power supply on the other with a smaller ripple, as you progress you'll go posting pictures. Regards
