who does mods for the Sony SCD XA9000-ES?

Might want to contact this site :

http://www.modwright.com/home/

I checked the link and they do not modify this player. Any other ideas?

You might try calling Modwright and/or RAM; you never know.

Who is RAM? Read the thread, re Modwright.

Why do you think it needs modding, or that the modder could do better than Sony?

Reference Audio Mods, Kyle Takenaga.

Why do you think modder would not?

Well, this is the issue. You know what you have with the stock unit. Can the mod improve it and is the improvement worth the cost? How will you determine it? Unless you pay for the mod and retain a stock unit for comparison with the mod, it's a guess.

I read the thread and it sounded like you had only looked on the site; didn't realize you had actually called them up.

The main challenge modifying that unit is limited real estate to add things like aftermarket clock PCB, discrete dc voltage regulators, or alternative 2-CH output stage. It's really packed inside. But worth a call to Kyle at RAM to see if he has tried.

BTW, if one were thinking about modding this unit, one of the first things would be to remove six silicon wafer AC rectifier bridges at lower left corner of image, and replace with custom Schottky bridges. Those $1 compromises in the critical power supply circuit are just one example of what afflicts consumer electronics independent of circuit design. The benefit/cost ratio of this replacement is much higher than any exotic power cord.
