Marantz 8001 SACD Player mods?

I guess what I'm asking is for the same total amount of dollars, would the modified 8001 trounce a used SA-15 or SA-11? Or would the stock SA-15 or SA-11 sound better than a modded 8001? I know the resale value always suffer. Sometimes mods are of the "I can't believe the improvement" to "can I hear a difference and do I like it better after the mod"? Would love to hear opinions from people that owned modded Marantz 8260's or 8001's. The cost for the mods start at about $750.

I have a Marantz 8001 SACD/CD player modded by Paul and Brian Weitzel of Tube Research Labs about a year ago (I bought it new for about $650 and had it modded for about $700). I formerly owned a Marantz SA-11, which I sold. I think that the modded 8011 has more detail than the SA-11, has better highs, and is more analog-like.

Just happened to browse the threads here, and saw this one, although it's nearly two months old. I have a couple of reengineered SA-8260's, essentially the same machine as 8001, and they are fantastic.
If you like the looks and feel of the 8001, and want to keep it, it can be made into something that's as good as anything out there. But you have to go for a complete reengineering of the player - new clock and psu, and a new output stage. Parts swapping modifications and other minor tweaks really don't get you much, performance-wise.
VSE and RAM are good modifiers who will get the most out of the player.
FWIW, at RMAF2006, RAM was showing a fully reengineered 8001 that had sound nearly identical to the top Esoteric player that they had for comparison.
As for resale value of a modded player, well that's somewhat irrelevant as you will want to never part with a fully reengineered player.
