When I went to a nvidia GT 545 V.card from GT 520 audio quality improved tremendously why?

post #1 of 7
Thread Starter 
I have been tweaking my system by changing video cards I first tried a nvidia GT 430, then a GT 520 and was not able to hear any difference in audio quality. The next thing I tried was turning on the headphone surround effect in my VCL media player and got a very good increase in quality of sound through my old hi-fi which includes a powerful power amplifier and old Bose 901 speakers. I next tried nvidia GT 545 video card and the sound Improve phenomenally . The video card in particular I tried was the PNY brand using nvidia GeForce GT 545 chipset and 1536 MB DDR memory.

So what was the cause of this tremendous improvement in sound quality? Was it using the brand PNY for a video card? Was it GeForce GT 545 chipset ? Or the amount of hardware acceleration that video card has compared to the others I tried? (I had video acceleration overlay turned on in the VLC media player.) What happens is the dynamic range with my new arrangement seems tremendously better. Human voices sound much more realistic. You can also hear a tremendous difference when listening to piano's every note sounding very vibrant. So please give it your best shot and tell me why you think this is happening. I plan on building a new computer shortly and sound quality will be a major concern.

The sound u may be hearing may just be placebo. Vlc surround and what not is not good and bose is not hifi. I am going off audiophile hifi headfi social standards. I can give more in depth stuff when i get home. Have someone swap cards for u and do a blind test . If u can still hear a diff i will chrck out specs of those cards. I have not heard of gpu doing much in audio unless like u said its accelerating something. For next pc audio suggestion i can and others can help when i get home.

ok now home. Like i said above. Have soemone do a blind test with you.
now some questions, what quality are your songs? ALAC? FLAC?(im guessing FLAC?)
If you go back to another card, do the improvements disappear.
if you play your music in regular itunes,foobar,media monkey, does it sound back to normal.

if you answered yes to the last question, then it means there is some digitial sound affect in use in VLC or something like that. the decoder's used in it could have something active you don't see and settings could as well. im not too sure what the full effects of video card assisted acceleration does in VLC per say as it is all diff, but that might have an effect. also please note that diff brands have diff accompanying software. did when u instal PNy was their software with it? sometimes software add on's also have DSP's in it. Your old hifi set is a great set of speakers. Only problem with Bose not being accepted by the general audiophile community and head fi is the same reason why Beats aren't. They are worth too much money for performance. i thought you were talking of regular $200 bose speakers or headphone's at first. if so then i would be a little meh on the dynamic range and how well they sound but the 901's are good speakers friom what i hear and should give you a good sound that you can tell apart. (WITHOUT considering price of course)

so did it? does using itunes,foobar,mediamonkey (preferably itunes as it is more streamlined and doesn't have any addon's or anything at alll)? if the "sound" is back to normal on itunes and the rest even with the card you are talking about. then there is some dsp in vlc active that is either comming from itself, it's decoders, external software etc. DSP's are usually not liked by teh audiophile community and are actually NOT what your music should sound like. if you like it..... then use it. what's most important is whether or not you like what you are hearing. if you want to actually hear what should be produced. use the regular software, and look into other equipment i will get into on the next paragraph.

so you are now looking for audio in your next pc? Computer audio or personal hifi audio? computer audio would just be..."reocmmend me a good sound card"
personal hifi is using your computer just as the digitial holder of media/medium and using something else entirely out of it for audio. personal hifi can be desktop, portable, or both. so you can have a hifi amp and DAC everywhere you go while you are out(the DAC can not usually be used portably...usually, many excpetions past $600 though) with your headphones or just want good sound on your laptop everywhere as use as a portable sound card. something like the fiio E17 is that. something desktop would be something like a maverick tube magic D1 which is both an amp and DAC, or the Schiit bifrost in conjuction with a valhalla, with the bifrost being just a DAC and valhalla being the amp. these are large expensive units.

Any other questions? rolleyes.gifthumb.gif

It will take me a while before I get to doing all of the above which you said since I am snowed in right now and can't get to a store to get another video card I could try.

Some additional information I should have included previously with this question. I have a mechanical switch that switches between my local monitor that I am using when I type this additional information and my other monitor near my LG 42 inch television through a 75 foot equalized HDMI cable. I also have some software called teamwork installed and another keyboard near my television. When I switched to my television as a monitor and use my better Bose 901 speakers the audio device being used in my television using the keyboard near my television to to right-click on my speaker icon to find out what audio device is being used, the one being used is as follows "LG TV-1 nvidia high-definition audio device."

On another part of these forums more dedicated to overclocking I asked some preliminary questions about what equipment to use to build a new computer system. I mentioned an inexpensive CPU cooler and a rather pricey motherboard and when I was asked about the disparity my answer was as follows. That all the ASUS motherboards which include DTS Surround Sensation UltraPC virtual surround are rather pricey once if not for that I would be budget minded on the motherboard as well as the CPU cooler. The response I got was I should use ASUS best soundcard instead of getting a pricey motherboard. That's soundcard was too pricey for my blood. But it raises the question in regard if I using a soundcard on a new computer, I will probably build in April, after the new new Intel CPU chips come out, give me another audio device output choice to use in my television over my 75 foot equalized cable. I know the sound cards themselves do not include an HDMI output I could use for my 75 foot cable I am using to get to my television and there Bose speakers.

I understand about the audio fights frowning upon effect software media player addons which manipulate audio, but I have been trying audio effect add-ons which enhance both dynamic range and give a virtual surround the fact and I like them and I also like none better than what I am hearing from the VCL media player. Some sound cards including ASUS brand include some of the audio effect in on. There are stores here in the Denver area such as micro Center which have a liberal return policies is there any soundcard I might try as part of preliminary research towards my build in April?

so sound can be switched from normal computer speakers to HDMI on your computer? (mine do too) and u use HDMI output to TV and then Bose? even then I still doubt the video card would put an immense effect. some cards use different hdmi versions like 1.2 or 1.3a or somethig like that but i doubt that changes audio drastically. since you are using add ons and DSP and what not, that could change what you are hearing a lot more. like, you didn't enable one when u had the 520, and then when u got the 545, some add ons enabled(happens quite often, my sound card likes to start up DSP sound equalization without notifiing me) stuff like that. you dohn't need to get the 520 again. that is just to do a litle scientific/technological experiemnt of add ons and what not and will take a whole day of your time! not really needed.

and yes they are right. no matter what motherboard you get. it would be ebst to get an external dedicated sound card. im not really too too into computer audo but a card i know is popular here is the Titanium HD's! i have heard raving remarks on how they are perfect for audio. if that price is....a bit low and you would wnat a higher quality card, then we will need to wait for more people to respond or you can go looking.
http://www.head-fi.org/products/category/sound-cards

this head fi page i linked above is very general, do not use it as a definite guide all these pages on head fi do is rank by score and popularity. most of us don't ever even add a product to our owned page as..it's just not something we do. but it does have good suggestions you can look at. so now i see the
Titanium HD and then Asus Xonar STX and i have heard about both being very good.

http://www.head-fi.org/t/576529/trying-to-find-the-best-sound-card-for-both-music-that-also-does-well-with-games

doing some research seems those are indeed two of the most popular cards. there are more, but those seem to be a good start. i would not have suggested these two cards if your store didn't have a liberial return policy because my setup is different then yours and i have never heard the titanium or STX's . i don't want you buying something this expensive and end up not being able to return it!

This is just a very quick reply before I have a chance to look into all you have said in depth. My purpose in building a moderately overclockable new system in April is not gameplaying at all I do not play computer games. It is transcoding MPEG 2 transmission stream video from my computer TV tuner. Most of what I will be transcoding is TV concerts like the one broadcast on PBS in its great performances series. Almost all the music I listen to I listen while exercising in front of my television old classic rock from DVDs, high resolution bit torrent music videos when I could get them. As soon as I upgrade my Internet service this February 17 I intend to get Netflix and see what music concerts are available there if any. So I do not know if that changes what you have said if I am only interested in the quality of sound on some sort of music videos be it from OTA TV or other sources.

Thanks for all the advice

most if not all "Streams" from online..are low quality in terms of audiophile standards. i would say about 160kbps MP3 lossy..... it may sound good..but once you know and hear cd ripped lossless encoded audio.. you never go back.

and...like i am saying. plz read through my posts in depthly and mark the spots that don't make sense and ask for elboration. wheee.gif
