Nice electronics. Resolution Audio makes some good stuff.
Heres the deal. While you own nice electronics, the Paradigm Studio 20s that you are using would sound a heck of a lot better on warmer sounding gear. This is mostly due to the Studio 20s aural signature. They sport very forward treble. Some may even consider it to be overbearing. On top of that, the midrange can sound a bit hollow. Typically speakers that retain this kind of sound are best suited for warm sounding solid state or tube components, or pretty much anything that has soft treble and a blossomed out midrange. The Resolution Audio gear you are using is just the opposite of that. Instead, it takes on a no frills, tell it like it is approach. Not a good match for those Pdigms. I think youd be much better off with a set of speakers that sport a softer top end and a fuller sounding midrange.
The Sierra 1s would be an excellent choice, and should match your existing electronics perfectly well. Im not so sure I agree with the above poster with regards to them being completely non-fatiguing, but I suppose thats a matter of reference, electronics, and preference. Nonetheless, they are good speakers and you get what you pay for outta em.
The Fritz 7 recommendation is actually a real solid one. Although these speakers are out of your budget, Id consider it to be a healthy step above the Sierra 1s in all-around performance. That said, I completely disagree with the hyperbole in stating that they among the best sub $4000 monitors around. They arent. Again with the whole reference, gear, and preference deal. However, youd have to REALLY disadvantage a pair of Dynaudio C1s in order for the Carbon 7s to take em on. Anyways, the bottom line is that the Fritz 7s are good speakers that should match your electronics perfectly.
