vir killer, we are almost the same boat, i start my hifi journey 20 years ago, i start my pc audio 2 years ago. i used monica2 usb dac and mod it with blackgate cap and japan resistor and follow all the mod from their forum, after that i compared it with my friend MBL dac in his system, monica2 sound still cant beat MBL even i using 70A car battery, so i start to do research to make my sound better, i upgrade my pc two times and changed my dac to weiss dac2 with firewire, i change my playback software from foobar,cplay to sawstudio and izotope rx advanced using for recording studio, I follow the acoustic treamtment as recording studio used like bass trap and diffuser(diy) Yes , diy mod will improved the sound quality but it had limited improved, I am also a musician, i have a band play at nightclub when i was young, so i know how the live instruments sound like. MY system is pc firewire to Weiss dac2 direct to Jeffrowland 8Ti HC to Hales concert five, interconnect cardas golden cross, powercord acrolink 4030, speaker cable Ah pui signature series one ( diy with 4N copper )haha
In DIY method to high end, we takes lots and lots time to fine tune the sound. tats the enjoyment of experience too instead of buying 1 set of rm100k system.
Battery as power source for hifi is hard to design as the quality of AC.. heard from an expert.. the current is slow and u losses detail. tats y i forbid that then go for AC for my soundcard.
LOL... hmm... may b i can tell some of my experience.. hmm may b you can try to make a dedicated power supply for ur digital transport soundcard. and .. another superB playback software called uLilith with customizable memory buffer running under cMP, i blive it would be one of the best solution as transport.. the weakness of foobar is not transparent enough lol.. i did use that previously. until i seen uLilith. the software was developed by a group of audiophile in JAPAN.. And they are really SERIOUS FREAKS... LOL. GOOD TO TRY. The playback source like your audio file, is crucial during the phase of transmission. uLilith is able to load up the entire audio file to your RAM then playback. That is one of the solution of reducing jitter. Like the latest innovation of PS Audio PerfectWave Transport concept.
one of the weakness of computer digital out of using USB, i guess it would be the reclocking phase of your DAC. Jitter might appear at there.. Thats why, i am using ESI juli@ that using clock oscilliator at email@example.com,88.khz,172khz and 24.576mhz@48khz,96khz,192khz. as well as my DAC matches the clock oscilliator is the same. Next time i can install another audiophile clock like newclassd neutron star and Audiocom or VSE Terrafirma uberclock LOL.. UBERCLOCK WAS INSANE TOO.
nevertheless bios setting, windows setting, and configuration jumper in your computer motherboard makes a big difference too. For example, the led light of your hdd or any other led lights. it generates plenty of noise that definitely affect your sound listening.. hmm.,.. if possible you can try the PC power cooling high end series PSU. it is quite good but, i dont think it is good for soundcard.. sound card itself should isolated with any other power source. hehe. connectors of your digital out better is to soldered.
your system setup IS QUITE CHOON! for me LOL... but i cant say anything before i experience it.. LOL.. good to talk to you here..!!! hope to keep in touch.This post has been edited by vir___killer: Sep 9 2009, 05:12 PM
