I lost the remote, I am not sure what you mean, when I put in a cd is defaults to 2 channel, that's about all I care about, surround is definitely not for me. No way, no way.
I followed his suggestion back in 2001/02 on my Sony XA-777ES and it did improve the sound marginally. I haven't adjusted the settings since then.
BTW good to see Jerome in this board again.
it sounds the same to me, perhaps because this is CDs?
or are there?
Just like cables, this type of tweak may be system dependent.
This actually isn't a tweak.
It's more a remedy for a design problem which their engineers hadn't had a clue about.
I reported it to the design team in japan. At first they revert back saying such issue shouldn't be happening. 6 months later they admitted they were wrong. By then it wss too late to do anything with the successor model, the scd-9000es.
But when it came to the time to create the scd-xa5400es, they took my recommendation into consideration, and replaced the software-based mch/2ch toggle function with a physical switch. That helped to resolve the issue - they never did explained why, but somehow putting the player in mch mode using software based control settings creates an extra load on the power supply that could have subsequently affected either the dac or analogue section.
The problem is inherent in all their mch players.
But some audio systems might not be able to reveal the full extend of the sonic differences. Their owners ough to revisit the setup to check what could be causing the bottleneck.
Great story and helpful too- jeromelang.
I repeated asked that they make it a true balanced output, and not the pseudo balanced type found on the 1st gen player the scd-1
I think they really didn't had a clue what constitute true-balanced...
as compared to RCA?
i suspect they padded it down internally so that the balanced terminals maintain the same output voltage as the unbalanced terminals.
I bet they felt that it is paramount not to inconvenience the end user to have to change the volume control on their amplifiers when they switch from balanced to the other unbalanced inputs and vice versa.
I tell you a joke -
When we were testing the balanced vs the unbalanced connections used between the Yamaha CD-S3000 CD player and the Yamaha A-S3000 integrated amplifier, we were flabbergasted that the balanced connections sounded softer by as much as 6dB.
A look behind the amp's rear panel soon clear the mystery.
There is an attenuator switch for the sole balanced inputs, which pads incoming balanced signal by 6dB, so that the playback levels are in parity with the other unbalanced inputs.
But, the balanced output from the CD-S3000 are also padded so that their output level is the same as its unbalanced outputs.
The nett result is - level is down by 6dB when using balanced connections with the attenuation switch engaged on the amp.
Stupid, isn't it?
I much prefer a physical or "toggle" switch to make listening changes to any CD/SACD player. It is a sound (no pun) function.
One cannot go wrong w/ Sony or Sony ES spinners for SACD playback.
Unless you do the setting change manually via the menu
