Zorkee,
In my mind, Philips never replaced the 1000. Marantz designed the 1000 when Philips still owned Marantz, while Philips did the 962 and 963 itself. The 963 does not have the discrete output stage, or two power supplies, like the 1000 does. However, I never heard a 963, so do not know how it stands up to a 1000.
ETR, congrats. I think you will be happy with the sound of the SW modded 1000. I am happy with my player.
However, I am worried now about it's durability. Friday, I had it playing because I had just made some mods to the power supply (above and beyond what Stan does). Well it was sitting there, I accidentally bumped it, when I was moving my amp around. After this, it would not read any CD

. Cycled power a couple time, and it was OK

. However, later on, found it would not read most hybrid SACDs

. Thought I was going to have to buy a new player. But, after leaving it off all night, it worked ok on Saturday

.
So, I am very relieved, but from now on, I am going to tweat it with kit gloves. Like I was thinking about taking it to Reference Audio mods one of these days, and comparing it to their modded 1000, but not anymore. It's not going to leave my house anymore, I am going to try to move it as little as possible, and hope the problem does not come back.
I was planning on making a few other changes to it, will have to think about it, and see if I think it is worth it. I am very happy with it's sound, and am so relieved it is working now.
