Marantz 8001 SACD Player mods?

IMO, mods would likely make the 8001 sound better than the SA-15 or SA-11.
Would it trounce them? That's really a matter of personal preference.

Some people write of "jaw dropping" experiences that others would
describe as a marginal improvements.

I will say that I have read little discussion on Audiogon regarding modded
Marantz 8001 players, so the pool of owner feedback is extremely small.

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.

I have owned and sold five "reengineered" players (nice euphemism!).

I've now purchased a stock player.

Tvad,
You know all about taking a bath on getting money back on modifications!
That's why you need to be sure you want to keep the player.
BTW, there's not too much Marantz left in my players.
