AKG K702's and Focusrite 2i4 - Page 2

post #16 of 22

Regarding burn-in. When I bought my brand new K702s three years ago I just out of curiosity used my notebook as a source/amp. Phones had harsh trebles and totally missing bass. When I used them with my DAC and C2C amp it was much better but still not as good as I expected. Playing a pink noise thru them for one week 24/7 at decent volume level to relax their drivers improved their sound a lot.  

 

Two weeks ago, just before ordering my new setup I used my notebook as a source/amp again and I was really surprised how good these phones sound now. It is not a magic, their drivers need to be relaxed first. 

 

I was also searching for better/perfect sound. I was hoping my previous setup will last forever. It was not cheap, spent 1100USD just for DAC and HeadAmp + some cables + K702 + HiFace. I loved the sound but felt more and more often that something is missing. My favorite PCM1704UK chips are already obsolete and their price went up - 90USD/ea. That was why I decided to make another step in my quest for perfect sound and I bought Reference 10.32 while it is still produced - what a huge step up in sound quality. Makes me curious how Master 7 + Master 8 (Audio GD top combo) sound.  

 

At the moment I am in love with its sound and except new phones (HD800) I don't see many possibilities what to buy next because at this level of sound quality you need to invest lots of money to get just slightly closer to the music or to perfect sound. The bad thing is the better gear you have the less music you can listen to as LoudnessWar and bad mastering ruined most of newer records. But it is another story.   

 

Enjoy your K702, I am sure you will love them as much as I love mine ;-)

I think I just may smile.gif

 

I had a long day at work and they were waiting for me when I came home.  The first thing I did was plug them into my phone (Samsung Galaxy Nexus) and listen to my "reference track". It's a song that I have loved for well over 15 years. I know it like the back of my hand on every imaginable sound system- even huge club speakers.  It sounded about how I expected from the phone with no amplification (quite meh). Then into my laptop through the 2i4. Yep. That was more like it. And any improvement from here on out will just be gravy. 

 

I'm absolutely glad I ordered the Objective2. The 2i4 just can't push these headphones. The headphone volume dial is all the way up and while it's got an ok enough amount of volume, it's just not being driven very hard at all. I would call it a comfortable medium/high amount of volume at the moment.  As expected my fillings aren't being jostled loose from my teeth with bass. And I didn't want that at all anyway. Far from it. I can only hope the amp will be here tomorrow and I can start listening to more tracks to get a feel for how they present other songs I'm familiar with.

 

As a caveat, it must be stated that my previous headphones were a pair of Sennheiser HD500's that I bought nearly a decade ago and they are absolute crap for anything other than casual listening. I've known this for years but I dealt with it and all my productions showed it, and suffered from it.  I worked around it as much as I could, but I should have brought them back on day one.  But quite honestly I didn't know any better at the time.  I figured that spending $100 at a music shop should have been good enough and that the weak link must have been something else. Also I was broke for a very long time so upgrading wasn't a top priority. Putting a garbage can on my head and banging the side with a stick would have been an improvement over the HD500's

Oh, and I must have confused myself by researching so many headphones. The K702's don't have a mute switch that kicks in when you remove them from your head. I know it was a feature on one of the pairs I was seriously considering but I can't for the life of me remember which ones. 

 

I'm actually kind of glad for this. It just seemed like something that could cause problems in the long run. 

 

So, burn in can commence with no rubber bands involved bigsmile_face.gif

The K702s don't have this but the K271 Mark II headphones do.

 

I have a pair of K271 Mark IIs which I use for monitoring sound on my video camera.

After a few days usage I'm happy with the combo I've put together. I have to put the O2 on high gain otherwise it's just not loud enough. I'm keeping the Focusrite 2i4 line out level (controlled through the laptop windows volume control) at 70% and the monitor volume level on the focusrite at about 75%, same for the volume level on the O2. The O2 makes all the difference in the world. The weak bass response has improved and overall the sound is just fuller. I re-equalized a song I've been working on and the difference is astounding. I'll have to make adjustments for a while until I get fully acquainted with how everything translates but so far it's just what I was looking for.

Common practice has it that you open the pots all the way from the center out until your amplifier and make adjustments there (unless we're talking about preamps).  I'm not familiar with you DAC however...

 

Try it out and see what you think.  Put the laptop volume and line out volume at 100 percent and adjust the O2 accordingly.

Good to know, thanks.  I wasn't quite sure about turning everything up to 11 so just played it safe. I appreciate the advice.
