I have had the Compass 2 for a month or so now and wondering what the general consensus is on the best quality input. Given the same output/settings do you prefer USB or SPDIF?
hey guys, just to check,
Is compass 2 a integrated amplifier/dac? so meaning it is capable of powering up passive speakers and feeding analog signals too?
You need to check the firmware version, or flash a known firmware with the upgrade toolkit that is provided on the website.
From there, once you're sure which version you have, you should install:
-1.1 for firmware #3
- 1.22 for firmware #4 & 5
- 2.0 for firmwares 7 & 8
The procedure is quite simple:
- Remove the old driver that might be present on your computer (go Panel Control -> Devices Manager -> Audio, video controllers -> Uninstall your "audio-gd" (firmware>3) or "SVB202" (firmware = 3) device and check "remove driver".
- Then you should delete from the VIA folder located in Program Files (x86) the following sub-folders: VIAudUsb & Setup.
- If you've got firmware #3, you should delete the HIEND folder in Program Files (x86).
- If you've got firmware >3, you should delete the folder in which you extracted the USB-32 drivers (from the rar package. If you followed Audio-GD installation procedure, it should be located in c: with a folder name that match the drivers (e.g AudiogdUSB32v2.0forwin)
- Extract the new drivers in c:
- Connect your DAC and power it on.
- Launch the installer and enjoy.
Note: the installation won't succeed if the DAC is off
I got my Compass 2 working after quite a few hours trying thanks to your much clearer instruction then Audio-gd. How tough would it have been for Audio-gd to spend a little more time having someone write more detailed instructions in better english. Just think of how many customers they have that would be just as thrilled by how easy it should be to install the drivers as they are with the sound of their equipment. Thanks for the clarification.
My pleasure.
I already suggested Kingwa to put a version in the name of the package that contains the firmware upgrade tool. It's always "USB32Firmware.rar". It contains all the firmwares that were released to date.
He should also make a driers version history and allow people to download older versions easily.
I much prefere firmware #3 over the newer ones with my NFB-27.
I'm very happy just to have my Compass 2 working with my computer for now. It came with the newest firmware. I have a extra chip so i guess i could have a different version of the firmware on each chip. Mine is not even broken in and i still have the Earth board to install and i want to do some recapping with Silmics wherever i can fit them. Are you switching chips to be able to ab the firmware without reflashing?
No I use the flashing tool, it's much faster and safe if you're careful enough.
In all cases, you have to uninstall and reinstall drivers, which may take some times since the computer needs to reboot 2-3 times in the process.
I stick with firmware #3 anyway and it also works with the Squeezebox Touch - albeit in Adaptive mode - which I rarely use these days anyway.
I use my Squeezebox Touch streaming from a NAS exclusively at home and my laptop on the road. I am probably better off leaving the firmware optimized for my Touch running the Enhanced Digital Output app.
I'm finding there isn't any room for most premium caps in the Compass 2. No way can i fit Silmic II's. The top line of caps in all the major brands are all too large around. It looks like the Nichicon FG series is the best i can do for the 100uf/100V and 100uf/63V caps. About the only decent cap i can find to fit the 1500uf/35V caps are Panasonic FC or FM series. I am not sure what would be a good replacement for the 3300uf/63V power supply caps. I believe there are some Nichicon 3300 and 6800 that will fit but i haven't really concluded if they are good for the power supply. I have read audio rated caps are not good when replacing the power supply caps. I'd love to here from someone who is also replacing the Nover caps.
Don't you like the Novers that come with it?
