+1 to Ralph. I switched to Dif/True balanced systems decades ago. That said, I do find differences in mfg XLR cables (including length of identical cables), which could be the XLRs themselves, and/or quality of solder/ joints, as well as the wire, shielding, jacketing...
Balanced versus single ended
From my experience, every situation that had both options, the balanced connection and/or increased gain sounded better, regardless of the bolume knob’s final position. More detail , air, emotional connection etc. The single ended cables used were good, not the bargain or so called high end extreme.
Sometimes using balanced or xlr it involved just the source, but optimally it carried through thd entire chain.
Anyways, my question is: has anyone ever thought that single ended sounded better?given the 2 options. Im only referring to a truly balanced connection.
I ask, because a manufacturer who makes tube amps, recommends single over balanced connection. Is there something else involved in this decision, additional parts or labor complexity? Is the signal path extended?
Thanks in advance

@tweak1 This is why I harp about AES48 and low impedance operation! If your gear is neither (for example any balanced ARC preamp and I'm not picking on them in particular) then you will hear cable differences. That's not supposed to happen. But too much 'high end audio' equipment does not support the balanced standard even though it really is otherwise balanced. |
It is a Peter Madnick design: Audio Alchemy DDP- 1> LSA Voyager 350 GaN amp. I never considered that the DDP-1 might not be True/Dif balanced. This certainly isn’t definitive from TAS review Robert Harley 3/2016: I began by listening to LPs, driving the DDP-1’s balanced analog input, and none of the other reviews say so, but here in an Agon discussion; I was told that the DDP-1 is completely balanced from the DAC chip to XLR jack including a 4-gang Alps potentiometer (one deck per phase per channel). . I recall replacing Silver Surfer XLRs with WireWorld Platinum Eclipse 8 - HUGE difference in quality. Im not inclined to A/B them at this point, though, it might eat at me. However, I used a sample Nano 45 graphene contact enhancer on the WWs, and can’t find the rest, so I assume that would skew the A/B |
FWIW you can have an entirely differential balanced preamp and it may not support the balanced standard. If you hear differences like you describe above it probably doesn't. Back in the 1950s in the Golden Age of Stereo a great number of remarkable recordings were made. They still sound great today- and the better our systems get the better these recordings sound. They have the kind of neutrality that they do largely because the balanced line system is an exotic cable technology- but instead of spending the money on the cables, the money is spent on driving them and handling them correctly so colorations are eliminated. Cable manufacturers hate it when I talk about this! That's because if the standard is supported in your equipment, its very difficult for them to make a sale if you listen to what your ears are telling you. |
Hey ralph, I’d mention a name on the whole balanced vs single ended thing, but he did not throw his hat into the public discussion ring, so I can’t. Not like it would mean much other than making them a participant outside of their knowing or permission. In the conversations with him, I mentioned that, in my mind, for balanced to work at it’s best, it should be designed in layout (from the active transmission end and at the active receive end) with an RF design and build mindset, where the field effects are a major consideration, down to the board mounting points and any local potential of the chassis and circuit boards in having any additional field effect interference. Just for the sake of the last little bits of attainable perfection in actual gear. Also, that these active aspects should be mirror imaged against one another and that includes a localized short run mirrored power supply for said mirrored circuit halves. If one opens up some high end equipment and in especially pro gear, one will not see this attempted, at all. And, this, done out to about a 1mhz level of signal handing capacity in the active circuits. Only then will the active circuitry be able to handle the micro perturbations well enough to damp/control them out to being largely below the complex sensitivities of the human ear, in the best of the listeners out there. Spectral, for one, tends to do things this way. There are others. (the designer I speak of, who agreed with this assessment, is responsible for some high level studio gear as well as home audio) |
