Raspberry Pi can't play/send native dsd via gpio...you must use amanero or similar device . Rpi usb to amanero to fifopi...with stationpi and amanero bridge.Hi Bogdan, thanks for you answer. I'm playing dsf files from NAS over a wired GE interface and this is not the bottleneck as I can play DSD256 natively over USB to the dual mono 9038Q2M audiophonics dac. I'm using the audiophonics 9038Q2M dual mono driver, but I've tried all of the available.
First of all I discovered there is no way to stream from volumio native DSD over I2S, it is always converting to PCM. I've been dazzled by the stellar specs of fifopi Q7 and I have not even consider a possible limitation like that on I2S. The only way is to use DoP but this is not changing the result.
Now the question (maybe for @iancanada) how to use FiFoPi Q7 at full potential. It has the capability up to native DSD1024 but I can only used for DoP up to DSD128 (even if should be capable to decode DoP up to DSD256 or native 1024). Is this a limitation from Volumio/linux Kernel, drivers?
Thanks!
thanks i will keep this in mind and calculate how long it takes to charge/dischargeYou can use the LifePO4 Mini 6.6 to feed a 5V LDO, but the only thing is that the RPi consumes pretty high current so that the pure time will be short before trigger the protection mode.
yea i agree im just looking for a costeffective solution right now but some builds look really amazingOf course we don't have to go to best of the best power supply out of the box. Things can be pretty satisfying with a linear power supply with a small 5v super cap on the output. Even more cost effective if cobbled together from the used parts bin. Later get another hit by upgrading to best of best.
well, atleast with supercapacitors i think they are way cleaner then regulators and are able to give way higher amp spikesWhat's the main difference between active power supply such as low noise regulators, and the passive power supply such as pure ultra capacitors and batteries?
