Is balanced necessarily better?


Assuming fully balanced equipment that also offers single ended connections, and no RFI problems, is the use of balanced interconnects necessarily the better way to go? My forum search indicates some who say balanced is better because the connectors are inherently better and because of noise cancelling properties associated with the signal flowing in both directions; and others who say for reasonably short runs and no interference problems that rca/single-ended connections sound better in many cases, maybe because the signal has less circuitry to traverse. This has come up for me because I am considering different preamp alternatives, and if I decide not to stay with a fully balanced system, I have more choices. To give things a try I substituted some old AudioTruth rca cables for my Luminous Sychestra Sig balanced cables. Except for the 6db loss in output, I have initially found the rca cables to sound a little smoother, with more rounded images, a little plumper bass, and what initially sounds like a more "musical" presentation. The system is a Muse Model 10 source/Muse Model 3 Sig pre/McCormack DNA 500/Aerial 9's. BTW, Steve McCormack told me the DNA 500 sees the signal the same way whether balanced or single-ended, and didn't seem to think the amp would sound significantly different either way. Therefore, even though many manufacturers are now offering more balanced equipment, especially at the upper end, others such as CJ continue to make only single-ended equipment. What are do you guys think, is balanced necessarily better?

Thanks guys, this is the type of interesting discussion from experienced folks I was hoping this thread would generate. I am in the process of moving equipment around which prompted getting some 3m ics so I can shorten speaker cable runs. I am going to try some sonoran single-ended ics, which Robert at Star Sound assures me will not have RF of EMI problems. I am still considering different equipment, which may include a single ended preamp, so I was encouraged with how good the single ended connections sounded on my Muse front end, since the flexibility of not going balanced opens up more preamp possibilities. From what I have researched and heard so far, balanced connectors have their roots in pro audio and are not necessarily better for home audio, and my listening so far has shown that to be true in some ways.
Another thought I have heard regards phase effects, and the inability of some balanced cable makers to appropriately design cables to resist phase shift, which might be one reason some believe single-ended sounds better for home audio. I heard one of the successes of using bybees is to correct phase shift problems. Any truth to any of that?
