What settings for a Marantz SA-10?

I have not yet tried these, happy with the default settings.

I thought in one of the professional reviews, the reviewer discussed what he heard with each filter and also when using dithering.  I believe the preferences were stated.  I don't remember where I read the review online but I know it is out there.  On my old Sony Sacd player, there were 4 filter options.  I liked the default the best (sharp rolloff) as it sounded the most natural,  Good luck.

Was it this review? I found it yesterday after posting this.

Yes, I believe it was.  

I've had mine for 4 months and it finally broke in thank god that was a long time!. 

Using many types of music, the best I've heard was dither off, Filter 1 and noise shaping 3-1. This gave the most transparent, dynamic and superb balanced sound. I used piano, stand up bass, Trumpets, and Vocals. Some all by themselves. These settings were the ones that made it feel like the players were right in the room with the correct tones, weight, and dynamics, natural. 

Dither 1 rounds things off and warms things up but in a bright system or unnatural like many systems today that would be a good choice for the dither 1 or 2 which might bring the weight and soul back to the music. After break-in, the SA-10 is outstanding in CD and SACD and USB flash drive files. Burning some music for compilations in WAV and even MP3 playback great and musical, WAV outstanding of course. 

Great value and worth looking into grabbing one, my past players have been Esoteric -X1, K-01, Marantz Sa7, Sony SCD1 and others that I had but had nothing but problems, some big boutique names who use OEM parts and some caused issues with other sections of the player, like overheating and shutting down and not reading discs. Stick with the Players that are built and designed from the ground up like Sony's, Marantz, Esoteric and a few others.
