good amp for the ultrasone pro 550?

post #1 of 10
Thread Starter 

Hey i have just received the pro 550 headphones and i am looking for a amp.

 

I am willing to spend around 50-100 on the amp it will be mainly used indoors so i dont really care about portability. i am mainly looking for an amp to boost the bass, im not a basshead but i do like thumpy bass in songs. also in the future if i do upgrade my cans to pro 900 i would like the amp to be able to support a high end pair of headphones.

 

thanks ;)

What sources are you going to be plugging the headphones and amplifier into?

i currently have the xonar ds soundcard and i have the htc desire HD for my phone/mp3.

 

ill probably upgrade my PC soon so i will use a different soundcard. im mainly looking for a bass boost for the pro 550.

 

i would be happy to spend more for an amp so i dont have to purchase a sound card in the future

 

thanks

By chance do the headphones sound better plugged into the HTC Desire?

Chance are (like 99%) the Xonar DS's DAC is better then your cell phone DAC

The Xonar DS does not comes with a headphone amplifier and chances are it's line-out/headphone jack has a high impedance :(

Where as your phone should have at least a basic headphone amplifier and a much lower headphone output impedance:)

So adding an external headphone amplifier to your Xonar DS should improve the audio quality of whatever headphone your using with the Xonar DS.

The PAV2V headphone amplifier ($70) should be able to work with the Xonar DS and your cell phone.

There is also the Fiio E11 & E12, but they can't function while their battery is being recharged.

There are also cMoy headphone amps.

Hey funny story the pro 550 came today but i have returned them and i bought a 2nd hand pair of pro 900 from ebay at a great price. i cant seem to find the PAV2V on the UK amazon but i might look into the fiio E11 because it is a good price. is their much difference on sound quality between a portable e11 and a big desktop amp for around the same price of £50? i was just wondering because i rarely go out with headphones so it might be more beneficial for the amp to be bigger if the sound it puts out is better.

 

thanks :)

The Ultrasone Pro 900 is only 40-Ohms. so I'm assuming they are easy to drive.

So it really would not improve the audio quality with a more "powerful" amplifier.

 

The PAV2V is sold on eBay.

The newer Fiio E12 might hold a charge longer then the E11.

im on ebay at the moment looking at some 2nd hand fiio e11, usually they sell for around £30 2nd hand so i will probably purchase that in the next couple of days.

thanks for your help

The Pro900 is source sensitive, a good dac would be alright. Some folks even recommend aftermarket cables.
