Firestone BRAVO 24/96 USB transport w/o drivers + reclocker? - Page 36

Lee, Thanks for all the info on your system. Can I ask you if you've tried this USB isolator http://electronics-shop.dk/galvanically-usb_isolation and how does it compare to the Olimex model?

Also, what are using as a link between the Olimex dongle and your DAC? Seems like there is some kind of adapter in there...

Thanks for your help, Duncan

Lee, also wanted to ask you which USB cable you were using that you'd bought off ebay for a fiver. Sounds like a bargain buy...

I got bored of the Olimex as it really veiled the trebles...this said, Firestone have just recently released an audiophile grade USB Isolator, and I'm quite tempted to try it: http://www.google.com/search?q=firestone+audio+green+key

 

It's too pricey in Europe, so I'd have a friend reshipping it to me...but I don't see it for sale in the US yet.

I currently use a $5 Lacie Flat Cable, it sounds very good to my ears: http://www.head-fi.org/t/576075/april-music-eximus-dp-1/60#post_8065304

 

It's also available as an extension cord in order to fit a USB Isolator without extra adapters.

This one was by far the worst sounding in the shout-out I posted in this very thread a little while ago.

Can't say that I have, no, as jplay won't do gapless and doesn't support VST plugins. My brain requires xfeed, otherwise it goes into kernel panic mode when I feed it dual mono.

 

And tbh, I love the sweet sound of uLilith and it's got many features I enjoy greatly(like the "open current folder" right-click option on any audio file...no need for pesky cue/m3u files anymore)

HI Lee

Jplay mini also in hibernation ( superb sound)  plays gapless, I also belief as a plugin for Foobar and Jriver it is gapless too

 

But even then

my post was not about Jplay :)

I have the dongle now in house too So i have to construct a nice 5-8V pws

I realize that real men supposedly use hibernation mode, but I kinda like using the computer while listening to music...it's also pretty convenient for watching movies to actually get a video display out of the computer biggrin.gif

 

uLilith provides native VST plugins support in 64fp, it would appear that the only way to use VST plugins in jplay is to run a system-wide jitter-ridden/resampling klduge around VAC, duh.

 

I plan on trying a few audiophile full-of-placebo tweaks myself, like feeding all the fans of the computer from a discrete laptop brick...I keep reading raving feedback about those filters, so we'll see: http://www.endpcnoise.com/cgi-bin/e/more_info/21176.html

 

They're polishing a turd by minimizing ripple and noise to the ATX PSU, I will use a discrete 12V brick I found attached to a busted LCD screen on the street, I shall find out whether fans are as evil as they say evil_smiley.gif

Either way, Firestone claim in their new USB isolation dongle sales pitch that "the noise from the power lines has effected the data integrity creating problems with the timing of the digital signal, known as jitter."

 

and this link says: http://hifiduino.wordpress.com/2011/11/24/which-digital-isolators-for-i2s-or-not/

 

"Galvanic isolation of the I2S output from the FPGA core and the USB ground virtually eliminates jitter and common noise originated by the PC."

 

OTOH, all those I2S isolators distort the signal to some extent...so it's never a black or white story I guess. IME, non-isolated coax sounds good off the Asus ST..but it's a potential groundloop feast. I think isolation is a necessary evil, and depending on your gear it can either outcome the cons or ever so slightly worsen the SQ indeed, but no groundloop!

 

And I'm using speed pots on all my fans that use PWM(pulse width modulation), it seems to be a very noisy method to throttle fans speed...moving them to a discrete PSU should be salutary regular_smile%20.gif
