I am currently waiting on my AKG k702 (my first ever Cans!) to come in the mail and I'm wondering if I would need a DAC. Probably or maybe not. I have a custom computer that I built just recently, and my mother board features higher capability audio solution with 108dB Signal-to-Noise ratio (SNR) playback quality to deliver high-performance, multi-channel HD audio. SNR is a comparison of the amount of signal to the amount of noise such as hiss present in the signal (expressed in Decibels). A higher SNR equals a better audio experience.
Now the DAC that I'm am thinking about purchasing is the Aune T1, it has a 120dB SNR. My problem is that I don't know how to evaluate the difference between 108 & 120 without hearing it. 108 to 115 could be a noticeable difference but I don't know how to measure it. All I know is that it has to due with its distortion and clarity.
Aune T1 is has a 24bit/96000Hz compared to my motherboard which is gives you the option of switching between 24bit/96000Hz to 24bit/192000Hz (higher=better), lesser ones and Dobly digital live 5.1 surround.
My motherboard came with the Dobly editor software which is just an equalizer that lets me control my audio frequency's. Akg k702 are to said to be on the bright side, well if they are to bright for my liking then I could just use my equalizer and adjust it. But if I went with the dac and it bypasses my sound card would it render my software useless? Like changing the equalizer levels wouldn't make a difference. Could I use the equalizer in media monkey (my media player)?
If I don't need the DAC then what do I need? Since most computers only come with a 1/8 jack and my cable is 1/4 do I just use the adapter it comes with, will there be a difference in quality, volume, etc.
Thank you guys, I am a new inexperienced headphone owner. All I ever had before was my apple ipod earphones and these old speakers I got. The only headphones I ever tested out where at best buy (which I thought were the cream of the crop), they had soul by Ludacris and beats, I was very very very very disapointed and thought whats the point of paying for top of the line headphones. Then I listened to these sony headphones and thought that these were pretty darn good which led to me doing a whole lot of research to where I am now.
One more question! can I replace the Aune t1 tube with a tube from guitar center? Does this DAC use a preamp tube such as this one.. http://www.guitarcenter.com/Mullard-12AX7-Preamp-Tube-107221301-i1388830.gc
