I have an M-Audio C02 converter that I want to use between my Imac and my dac. I have no idea how to hook it up. I think I need 2 cables, one from my Imac into the converter, and from the converter to my Dac. Can someone tell me what cables I need, and do I need to spend a lot of money on them...

Does anyone else own the Ultrasone version of the RPX-33 that can comment on the differences between it and the stock version?

I am about to purchase a Rudistor RPX-33 amp. Rudistor says they can make me the special version that was made for the Ultrasone Edition 9s. What is the difference? Both hardware and sonic? I am using a Resolution Audio Opus 21 CDP. Thanks.

Do any headphones sound better in 3 channel than with balanced with this amp?

Does anyone have experience with JVC DX1000 and the Beta22 3 channel?

Rudistor RPX-33 and Resolution Audio Opus 21.

This is an excerpt from a review of the source: It's got a slightly wet texture that's quite different from the drier, somewhat more cerebral sound of the Ensemble. The treble in particular deserves mention for completely lacking that peculiar and stand-offish dry, thin and somewhat chalky...

I am putting a system together and have picked out components that are supposed to be truly great by themselves. I want to make sure they are truly great together. Both the amp and source I have chosen are said to be on the "Wet" side, but in a good way. Will these sound good together?

What headphones are known to have synergy with a Beta22, single ended and active ground?

Do these work well together? I mean, I am looking for THEE amp (solid state) that will drive these headphones. I was about to purchase a Rudistor RPX-33 because it seems to be THEE amp for the Edition 9s. But is the Beta better (single ended with active ground. The Beta will cost $1800 (built)...

I would like to know if an NX-33 amp in balanced mode is better than an RPX-33 when using Ultrasone Edition 9 headphones. The NX-33 is discontinued, but if it will be better, I will get one used. Thanks for any help.

I want to burn CDs of albums I have in Itunes so I can play them in my regular CD player. I no longer have the original CD as they are mostly from CDs I got at the library. Will they sound just as good as the original CD?

How important is it to consider headphones when choosing a source? I am planning on purchasing a Rudistor RPX-33 to go with my Ultrasone Edition 9 phones. I am seriously considering a Resolution Audio Opus 21 CD player. This is supposed to have real synergy. But I also plan on purchasing...

I am looking for a source that will have GREAT synergy between this amp-headphone combination. I don't want to mention price, although I do not want to spend more than is necessary. I would prefer to use Itunes from my Imac. Please, can anyone recommend a great source that is hopefully...

Which is better for controlling the bass on a pair of Ultrasone Pro 900s? I like lots of impact. Thanks

Still unsure about the differences. I think I need to try 3 or 4 different pairs and return the ones I don't like. Do any retailers allow this?

Between HFI and the Pro line , which Ultrasones have the hardest hitting drum sound? Not necessarily deep bass, but hard hitting impact? I am interested in the Pro 900, but am concerned that their deep bass may take away from some midrange punch. I like the sound of drums when I attend a...
