jrisles Posted October 4, 2007 Posted October 4, 2007 Hi Guys. Not wanting to hi-jack the Yamamoto thread in the "General" forum i thought i post this question here in the Amp section. This is in fact related to a Headphone amplifer. With some excitement at present about the Ultrasone Edition 9 headphone matching with the Yamamoto HA-02 amplifier i was wondering if anyone on here is familiar with the Ultrasone RPX-33 Headphone amp designed to match with the UE9 Headphones? This unit retails for $US1800.00 & well very well constructed. http://www.ultrasoneusa.com/rpx-33.html cheers Jeff
jrisles Posted October 4, 2007 Author Posted October 4, 2007 My apologies. What i thought was an amplifier made by Ultrasone is indeed an amplifier manufactured by a company called Rudistor. Apparently the Rudistor RPX-33 MkII and the UE9's are a match made in heaven. http://www.rudistor.com/soundsystems/amps.htm John Marks of Stereophile Highly Recommends this combination in a recent (June 2007) review of Stereophile. http://stereophile.com/thefifthelement/607fifth/ Another option for you potential UE9 owners? cheers Jeff
