marantz 11s2 sacd player modifications

Mitch2 has a good point. I have a SA-7s1 it slightly errs on the warm side of neutral. My friend has the Lector CDP 7T player and it is much warmer and the highs are a little rolled off. I think that would be more to your liking.
Try to get an older model,they are much warmer then the updated ones. You can even roll tubes of your liking.

The CDP 7TL MkI and MkII used the BB PCM-63 DAC chip, which is now obsolete and which also doesn't support the higher upsampling rates. Lector went to the BB PCM-1704 chipset in the MkIII when they couldn't get the 63's, and the upgrade resulted in better resolution with only a minor loss of richness and warmth, a good trade IMO, but those preferring the ultimate in a liquid, warm, rich sound (like Tennis) may want to go for one of the older models. I belive the MkII addressed several upgrades over the MkI including upgrades to the transport mechanism so the MkII would be the sweet spot, if that is what you are looking for. Brian Ackerman with AAudio Imports, the importer at the time of the model change from MkII to MkIII, told me only about 10 or so MkII's were sold in the USA before the change. I owned a MkII and was able to compare the MkII to the MkIII when I had both in the house. IMO the MkIII is the better player because of the improved resolution and bass definition, but both sound very nice.

My Marantz SA-11S2 has the Underwood Level 2 Mod.

I have what I "Dreamed" of, a SACD player that
sounds like a "Master Tape Player" , except it's a Disc.

Every positive attribute, can be heard after the Mod.

Better resolution,tighter, quicker response,
Better imaging,focus, etc..

IMHO, this player will hold it's own with the Best.

We ALL hear differently, but my ears have never been
more happy.

I am so very thankful!

Love Your Music!

I sure am!

As a SA11-S2 owner, I can add that you will be very disappointed when expecting a tube sound from the SA11-S2. For a tube sound you test the Raysonic of MF's.

Welbourne Labs sells hybrid modules for players. They come with an outboard power supply, which is a very good idea. This way you can use a power cord optimized for the analog stage, and another for the digital. Same for PLCs.
The modules have a tube input, and mosfet output, no coupling capacitors, so they should give a nice full, somewhat more 3D sound.
