I have to agree with Sherod, the MAS Sig IC is truly a high end interconnect. A couple of years back I was co-owner of Richmond Audio & Video and was an MAS authorized dealer. At that time our reference system consisted of Duntech Black Knights(originals with Dynoaudio drivers) driven by Klimo Linnet 100 watt tube, class A amps. Both ICs and speaker cable were MAS (gray) silver which produced some of the most realistic music I've encountered. I am still using the MAS gray on my Rel sub. I received my 1mm balanced set of MAS sig ICs 5/15/04 and it's currently breaking in. My first impressions after listening is not suprising, Stu always gave you great performance for a reasonable price. First without going into great detail my system is SS Krell amp/pre, ML Dac, DCS Purcell, CEC transport driving Piega speakers. Digital ICs are all Goldmund Lineal and Jena Labs Sinewave 7 IC from Dac to preamp. From the preamp to amp is a Purist Audio Max. The Purist Audio was removed and the MAS sig inserted. The MAS unbroken in, went head to head with Purist Audio ICs and in my opinion the MAS on cymbals and piano bested the Purist, however; it appears the Purist was much better in layering the soundstage, although the depth of the soundstage was equal. It appears I will have to wait until the MAS fully breaks in to see if this changes. At any rate, I know ultimately the MAS will probably be used as a source IC as in my Esoteric DV-50 and the pre to amp will be another Jena Lab IC. However this does not discount the great value and performance the MAS Sig gives the music listener. Once again, Stu Kudos, great IC.
