Direct coupled with transformers is one way to go, but according to the builder of the Dude it has sonic disadvantages - and certainly in his design. Most amps have ample input impedance and only a few can cause some rolling off at the extremes. A... 
Is it save to convert XLR to RCA?
Ok , here is what I found. With the ic's connected to the direct inputs (RCA) on the amp no matter which input I chose on the selector the buzz was there. Did not matter as long as the ic's were connected. When I connected the ic's into the crosso...

Ok, I have a question. I want to use an xlr cable from my pre to amp. My pre is only RCA out. I want to purchase this Jensen transformer mentioned above and am not sure what to buy and if it will work? I assume they make one that accepts RCA from ...

One more thing I really need to add. Paul has a great ear and uses coupling caps in the Dude that are neutral sounding and of high quality. Understand I am a budding DIY guy and have modified amps, speakers etc... I enjoy it and am learning. Paul ...

The Duelund caps are the coupling caps. I also put these in and Pat and I are amazed at the sound. Keep in mind they cost $400 for the set of 2. We purchased the 3.3 uf value. They are first rate caps and very expensive.They replace the small caps...
