    Atma-Sphere S-30 MkII Stereo OTL Amplifier

    I have a diy Nelson Pass designed BOSOZ balanced pre-amp. The S-30 was measured at 2.83v input by soundstage.com It does a shining job and I'm pretty certain i'll have that pre forever. That being said, I wouldn't recommend a passive pre for this amp. I've had it going with a lower voltage output pre before and it sounded great, just didn't get the full 30-45 watts of OTL POWAH. http://www.soundstage.com/revequip/atmasphere_s30mkiii.htm

    I think they updated them since they originally came out.

    DSP options for your Pro Klipsch Audio

    I use Dirac for everything except the subs. I then REW the subs separate and input EQ into the Inuke dsp software.

    To my knowledge the Analog Devices AD5791 is a 20 bit R2R ladder structure. http://www.analog.com/en/analog-dialogue/articles/20-bit-dac-and-accurate-precision-voltage-source.html

    DSP options for your Pro Klipsch Audio

    Previously i used the hypex on a passive xo for the low and highs. They handle themselves very well and crystal clear. I like what the OTL's do to the mid range for 2ch music however. When i do my theater i will have the HF as Ncores, their dynamics are amazing and super silent. Zero background noise

    I bought the S-30 Atma-spheres used, they are the Mk II model not the updated versions. Cost me $1400, which was comparable to some of the Transcendent Sound options. I went with the Atma-Spheres because I had balanced connections all the way through and didn't want to change. Probably didn't matter in the end but I'm a little OCD on weird stuff like that.
