Dk604 I have the RME version 2 and MHDT Orchid. Both are very nice but different. I use both in a speaker system. The RME is very clean and detailed, Orchid has rolled off highs and can come across with deeper and fuller soundstage but can't dig as deep for detail or information. Orchid can also sound more natural or musical on some recordings. I did add a Teddy Pardo power supply on RME, it did help with soundstage, made it sound fuller, more musical and noise floor dropped which in turn help with detail, very worth the investment. The Orchid sounds good with less complex music but when things get busy things can fall apart. Not so with RME no matter how fast or complex music gets everything stays together. Can't beat all the features with the RME. I like both and would not be without either of them depending on what mood I'm in.
What? The RME with the stock PSU is noisy? That's absolute news to me from my own experience with the unit for the past 24 months. And pretty much everyone else seems to say that it is a standard in pitch black no noise performance. Or am I misunderstanding the term noise floor?
