Difference between Marantz PM-11S1 and S2

Have you googled or searched here? Check out Audio Asylum also.

Good luck. I spent a lot of time and effort trying to find out the differences between the MA9S1 monoblocks and the revised version, the S2. I concluded, with no help from Marantz or my local dealers who were clueless, that therewere in fact almost no differences except some capacity was added to the power supply. Therefore, I chose to buy the older version at a savings of $2500 to $3000 and frankly, the sound is superb. My take is that I would start with the older model and see if you like it.

De plus moi aussi j'ai été très surpris, j'ai acheté à Paris en occasion le complet..SA7S1/SC7S1 et 2 MA9S1.
Par curiosité j'ai enlevé le capot du MA9S1 et je me suis aperçu qu'il était installé à l'interieur l'alimentation du S2
le transformateur est blindé dans sa capsule NOIR, l'importateur Marantz m'a dis de ne pas se fier au photo sur le net, donc en france si vous avez la possibilité d'acheter des S1 n'ésité pas.

You can say that again, Gormgoov.

The 11S1 is now discontinued while the S2 is still available. However I now believe it is on the verge of being replaced with the S3. Check Marantz.com and search the models. Musicdirect.com may be a good place for information as well.

From some of the reviews I have read on the two, the S2 was to have a little more warmth and tube like sound to it's presentation. In my stereo stable I recently purchased a PM8004 integrated. It falls under their reference series where the PM-11S1 and S2 reside. To best the 8004 the above models must be smoking.
