Balanced or Unbalanced?


Hi-end should be about as few compromises as one's budget will allow.

It's a shame (or a conspiracy) that hi-end mags do not educate us on the basics, such as unbalanced circuit designs vs differentially balanced designs and XLR connectors/connections vs XLR connectors/connections and their relative impact on music playback. Why do I mention "conspiracy"? Magazines seem reluctant to bite the hand that feeds them- the majority of manufacturers are still in the dark ages selling unbalanced gear. Why? It seems you can't teach an old dog new tricks.

Hi-end roots are based in unbalanced designs. When the few differentially balanced designs (XLR) first appeared on the market, they were too expensive for most of us. Today, several manufacturers offer XLR designs that are competitively priced with unbalanced designs.

Think about it, sharing the L/R signal on circuit boards and through parts cannot be a good thing. Adding insult to injury is the RCA connector. A system is only as good as it's weakest link and this is the RCA connection. In response, several manufacturers have improved the RCA connector, but to what ultimate result? You can put lipstick on a pig, but it's still a pig.

Reviewers (and I blame this on editors) typically allow balanced components to be reviewed within the confines of an unbalanced system. See The Absolute Sound August issue review of the Raysonic 168. Consequently, we are not informed on the components' ultimate sonic value.

If you are on a quest for best sound, begin to replace your RCA based components with differentially balanced. Most will accommodate RCAs or just buy RCA/XLR adapters until you fully transition.

My CDP, pre -amp and amp are all bal units, I recently switched from all S/E to all bal in the same cable. The improvement was impressive, more than I expected it would be. Inserting bal from CDP to PRE first the sound expanded, became airier, the sound stage increased and the sound seemed "less dense" more alive cleaner and clearer!! I used a SLM to keep the volume at 74 db with S/E and bal. When the second bal cable was inserted from pre-amp to amp there was a substantial increase in bass. I was told each unit sounded better using bal I/C but the amount of change was a surprise!! It was as if the S/E had been choking the system down!!
Hi Shadorne I don't know enough to disagree with you I only know what I heard, also there was an experienced audiophile with me at the time and he was more than a little surprised at the changes in fact he was bummed he had to run S/E from his Ref 3 to his VS-110 after hearing the improvement in my system. The biggest change was from the CD3 MKll to Calypso. I just bought the CDP from Audphile1 he strongly advised using bal I/C saying the unit sounded better bal. I was told the same thing about the Calypso by an audiophile whose experience I respect. Is it possible these two units that are bal designs and individually improve with the use of bal I/C improve even more together? I kept the sound level at 74 db with S/E Sky and Bal Sky so we were very surprised how much better the bal sounded we both looked at each other in disbelief asking are you hearing what I'm hearing!! I'll A-B tomorrow to recheck, I don't have time today as we're off to the USC-OSU game soon!!! Fight On!!!!!

Shadorne you had it right it was a noise problem!!!! There was "glare" with piano in the higher notes, I thought the CD's were poor quality or that was just how "most" CD's were going to sound, depressing!! I used "The Ray Brown Trio Live At The LOA Summer Wind" for the A-B ing.
For an unrelated reason I bought a used set(4) of AQ Sorbogel Big Feet and put them under the Calypso just to hear what would happen. The "fuzz" at the peak of the notes disappeared, the notes were clean/clear!! Today I A-B'ed the Bal and the S/E and they were extremely close, only a very slight difference in what appeared to be warmth.
Next I placed isolation cones under the CD3, they cut-out a tad more "fuzz" and tightened everything up!!! At this point I puy an 1 1/2" maple board under the amp to further reduce vibrations. Now the Bal and S/E were even closer, a great lesson in the degradation of sound by vibrations. Bal cable was left in from the pre to the amp during the elaluation.
The Calypso must be extra sensitive to vibrations the change was so dramatic
UH OH here I go again!!
Vett93 I didn't mean to imply the signal had another 6db of gain just that it became bassier.
Thanks for dealing with something you easily could have blown off, the sharing of everyone's reactions/thoughts kept me thinking about the cables and the importance of dampening vibrations for clearer sound!!!!
