Re: Headphone Recommendations ?

I have the PS500s and they are great, and probably the best value Grados. I swapped the cushions for the larger g-cush, as used on the PS1000 and that was very worthwhile. Much more comfy and improved balance of the sound. Not quite a match for my Hifiman HE-6s but work well with portable sources, u...

Re: DACs -- a technical discussion

There are certainly more than one valid approach, so it'll be interesting to see what you might produce in this area John. I spent a few hours looking into the FPGA development route and decided I did not know enough to realise something beyond the "toy" level of sophistication. There is a...

Re: DACs -- a technical discussion

My understanding of the Chord dac architecture is that the FPGA does the de-jitter, upsampling and noise shaping required to produce a high bandwidth bitstream (1 bit) pwm datastream. The Pulse Array is very similar to the dcs Ring dac (at least in principle if not execution) in that it using an ave...

Re: Tweaker's Rash

You could always run % cd / % rm -r * and go listen to a CD... (NB This is a joke!) But quite tempting sometimes! If the bbb had an external mclk working on slave mode would it solve the issue? Bbb unsuitable clocks? The proposed TPA cape will provide high spec clocks for both 44.1k and 48k file fa...

Re: Tweaker's Rash

Hi Nige There is no simple step-by-step for this. I cobbled together from all over the place. Use the latest Debian Bone Wheezy from the Beaglebone Community pages. Use the I2S driver and installation process from here: http://bbb.ieero.com Use the Squeezelite installation process from here: http://...

Re: Tweaker's Rash

I have I2S out of the BBB today, dropped into my system in place of the RPi. I have a basic Debian build with Squeezelite running, cabled Ethernet via a wireless router so I can use my android LMS remote, linear PSU. It works very well (but only on 44/16 flac or wav. High resolution files cause stut...
