yea the akg k553(and the whole K55x line) are quite sensitive. What is your setup? The noise could be coming from some where further up your audio chain.

Just spent 30min listening to cars noises :) thanks for the link

but for a couple bucks you could tap into the main power amp and add a second 1/4'' jack, then you would have high and low power output options running off two different amps

I am kind of surprised that there has been almost no mention of the BasX TA-100. Speaker and headphone amp with dac that has usb, optical, coax, and bluetooth. Not sure but it sounds like the ta-100 has a separate headphone amp from the speaker amp(guessing because of the description and the...

I am using it with windows 10 right now, works fine

It would be interesting to see measurements of the th-x00 the way that audeze does. Being a closed cup it seems like variations in wood should have a larger effect on the sound. By variations of wood I mean not only the type(purpleheart, mahogany, ebony) but the variations within each of the...

So why not use/cannibalize a set of he350? they are going for pretty cheap used, and you dont have to feel to bad about it since they dont sound all that great to begin with 

I have the t90 and the he500 and I like the he500 a lot more because it plays fairly well with all genres and is more forgiving. The t90 is awesome with certain types of music, but it will require good quality recordings. The T90 has a larger soundstage and the bass has a different feel to it. I...

I would be interested, just not sure until a date is locked in

I have actually been having issues with this recently(last couple months) while using chrome too. It seems like the search function randomly stops working. If I place the cursor over the search icon in the top right, it will highlight it but clicking it does nothing. The solution that I found...

Just got my th-ebony pretty happy with them. Sound is just about exactly what I hoped for. Bass has nice impact/rumble without getting in the way. The mids are nice and clear, seem a bit like they are lacking lacking body compared to my planars(he4, he500, lcd2). The treble is honestly my...

    this is dt880 comparison from headroom, they don't have t90 balanced measurements. the graph is just to show the use of balanced amplification will have effects on the sound sig. too bad more people don't have measurement rigs to show show effects of mods and other changes
