You may want to email Paul at TRL and see what he thinks about your upgrade or mod path with the 555ES.
I am sure a place like TRL or SACD mods could improve the stock player. The question is whether the technology used on the 555ES has been passed up by a newer (and maybe cheaper unit).
Something like the Sony ES2000 unit may have more upside after a mod than a 555ES. I know it sounds kind of odd, but the Sony CE595 (a $150 unit) that I had modded by TRL was a monster. The best digital I have had in my system. The ES2000 is a believed to be notch above the 595 by those that have heard both modded and it is about $150 more stock.
Now certainly initial build quality has a co-relation to the outcome of a modded unit, but maybe not quite as much as one might think.
I guess all I am saying is that the newer technology may offer some other alternatives for you.
Good Luck.
