marantz 11s2 sacd player modifications

The Marantz SA11S2 is a fantastic player. Why make modifications on it? If you want it better buy the SA7S1.

the changes i want will not be achieved by owning a 7s1. i am interested in achieving a tube like presentation, by softening the sound and shifting the spectral balance.

the 7s1 is more resolving than the 11s2. i am not interested in resolution.

Mr Tennis, your search for the player that is "just right" is well documented and always interesting. I cannot resist asking you since "the marantz is not a warm sounding player," and if you want a warm sounding player, then why did you purchase the Marantz? Why not purchase a Lector CDP 7T, which is a wonderful sounding player with very natural bass and treble, and the full, warm midrange you are looking for? I know you have tried the CDP6 but that is not the same as trying Lector's best player. If this warm, rich sounding player is still not warm enough for you, you could always adjust the sound further by your choice of NOS tubes.

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.
