FS: Hifiman EF5 (EF-5) Hybrid Headphone Amp with upgrade

Will Ship To: Anywhere

Hi,

I am selling my Hifiman EF5 Hybrid Headphone amp with dual BurrBrown OPA627 opamp upgrade.

 

The amp is in very good condition. The blue LED power indicator light no longer works. It does NOT have any functional effects at all. I actually like it without the blue light. Less cheesy if you ask me. :-)

 

it's a very sweet sounding amp with big power output (2W into 50ohms if i remember correctly). it is able to drive most of the power hungry orthoes maybe except the mighty HE-6. It is also a good match for dynamic headphones as well. I have paired EF5 with a lot of different types of headphones, and i feel this is the most universal headphone amp i have ever used. You can read the review at http://www.headfonia.com/hifiman-ef5-review/

 

I have upgraded the stock opamp to dual BurrBrown OPA627 opamp. You can read the benefits at http://www.tweak-fi.com/apps/blog/show/8888897-3-tweaks-for-cheap-.

 

Because of the size of the dual OPA627, the top clear panel can no longer be fully closed. It doesn't affect normal use at all and maybe even improve the heat ventilation. I will also include the stock opamp as well as the screws if you wish to switch it back. Personally i think OPA627 is a very good upgrade.

 

EF5 currently retails for $499, and I am selling it for $290. Buyer pays for shipping and 3% paypal fee.

 

Thanks for looking.
