The WA7 is one of the few home headphone amps that sounds great with full-size and 
in-ear headphones. - Audiophiliac 

 

 

This is possibly the most linear DAC and headphone amp I've heard.  

-Positive Feedback 

 

 

 

The Woo reaches DEEP, and is POWERFUL. It’s everything you want it to be and just 
a tad more … because it’s so damn sexy you feel like you stole it from the future 
somehow. -Humanovation 

 

 

 

Appreciable about the WA7 was that whatever headphones or IEMs I used with it, the 

performance was consistent. -Currawong @ head-fi.org 

 

 

 

the WA7 is practically a steal in terms of sound quality and physical presentation. - HP 
Soundings
