Sony SCD-1 balanced or unbalanced?


hello which sounds better unbalanced or balanced? Also could use some preamp recommendations probably tubes for the Sony SCD-1 source.

Jadem6, you are correct, in your case. No doubt if you're using expensive (and very good sounding, I might add) cables, you are also paying attention to clean power, keeping interconnects away from power cords, etc. You will not hear any differnce between RCA and balanced -- unless you go past 2 meters, in which case balanced will begin to preform better for a variety of reasons. Also balanced MAY be less subject to power problems as Bluefin has noted. To that, I might add that ther may be a synergy between certain types of cables and components and the balanced/unbalanced question will become part of that complex, black art equation. In your case, RCA sounded jsut the same, so it is! Others, with different preamp/amp combos may find exactly the opposite, so I'm sure this debate will never go away. In my case, RCAs from my SCD-1 to my Placette line stage EASILY outperformed a fully balanced set of NBS cables into a Classe PD-60. But it wasn't the cables, it was the preamp that made the differnce -- the Placette was clearly superior -- the cables made the A/B easy because they just got out of the way -- and it didn't matter whether they were balanced or not. However my runs were short (1 meter) so your mileage may differ. --Lorne
I am using singled-ended with my SCD-1. To me I really do
not see why I need to use XLR connections because my SCD-1
and pre-amp are on the same rack. XLR is designed for very
long cable runs, e.g., from microphone to recording console.
For usual high-end equipments I do not see the point of using XLR or fully balanced circuitry. (If your pre-amp is three blocks away, then you should definitely use XLR.)
On the other hand I am using the Transcendent Grounded Grid
pre-amp with SCD-1 and I am very happy about it. I would suggest you give GG a try, and you can even build it yourself for $500! Several months ago when I was looking for a tube pre-amp to match my system, I was thinking about
Audible Illusion Mod 3A, and ARC LS-25, but finally I choosed GG by the very obvious reason: $$. My current system consists of:
Front end: Sony SCD-1
Pre-Amp: Transcendent Sound Grounded Grid
Power Amp: McIntosh MC-275 Gordon Gow
Speakers: Quad 989
I found that with my SCD-1 that running balanced, the unit was very inferior and sounded much better when run with single ended cables.
It seems the SCD-1 doesn't have a true balanced output, instead it is converted from the unbalanced one by some additional circuitry. At least this is what was discussed in AudioAsylum....
I am using the SCD-1 in an all balanced system (ARC LS25 to ARC VT100 MKII). The balanced mode (using Burmeister Silver interconnects with both XLR and RCA terminations for comparison) is clearly superior to the unbalanced mode, in my system. Presumably, the benefits of the balanced mode is dependent on whether or not your preamp and amps are fully balanced designs.
