Does using a rca to XLR adapter compromise power and dynamics of power amp?


Currently using rca to XLR adapters for the connection from my A/V receiver to my Krell power amp, since the Krell does not have rca inputs on it.  It has recently been suggested to me that by doing it that way the output voltage may be reduced from what the Krell would be "looking for".  Thoughts?

Thanks very much, almarg.  Yes, the amp is Krell FPB 400cx, and the receiver is Denon AVR X5200.  I just looked at the X5200 specs and the only thing I could find that may be relevant is under the Analog section, where it reads:

Rated output:          1.2V

Now, my guess is that that is some sort of nominal output and that it can produce peaks higher than that.  Is that normally the case? 

With regard to the Jensen adapter, I looked at their web page, and it seems the primary selling point is to eliminate "hum and buzz".  I currently have none of either of those, as the system is dead silent until a signal is fed.
OK, yeah, my speakers are rated 4 ohms and around 92db sensitivity.  I'm thinking I'm in pretty good shape with my current situation.  I just didn't know if the rca to XLR adapters would in any way limit the amp's ability to produce bass transients, slam, and impact.  But it appears that should not be the case.  Other factors, such as speaker cables and interconnects, may be the way to get the best out of the amp and to the speakers.
