This is the amp recommended by Ultrasone to drive Edition 9s. It's a very magnificent amp in its own, it also drives AKG, Sennheiser, Beyer, Grado and Sony (markl used it with Sony R10) very nicely.

 

I paid 1300 euros for the amp, plus GST (S$123 cost) altogether paid around SOLD. Am looking to sell at SOLD or make me your best offer.

 

Audition can be arranged.

Some impressions:

 

"To put it in as few words as possible: The RudiStor RPX-33 mk2 is a phenomenal headphone amp. Paired with the Ultrasone Edition 9, it's extraordinary." Stereophile

"the RPX-33 achieves two seemingly contradictory goals-- it provides incredible resolution, cleanliness, precision and naturalness, but at the same time sounds deliciously meaty, full, vivacious, liquid, energetic, solid, powerful, and defined." SH Forum

My loss is your gain. Thanks for looking.
