Simao-I heard the 11S2 at the 2010 Akfest driving a Paradigm S8v3 and was impressed. The midrange on the S8v3 was excellent and I do believe the Marantz(pair)PM-11S2/SA-11S2 were responsible, living up to the reputation of having a near SOTA midrange. Some say the Marantz treble is a little truncated but I didn't notice it on the Paradigm. Build quality is 1st class and the power rating is conservative with the 11S2. I've read the phono section is top notch for an int. amp. I have no reason to dispute this after hearing/seeing the 11S2. FWIW-With my own system it came down to the 11S2 and a Valve Audio-Predator. I went with the Predator only due to the versatility(tubes)and more power.
