True, I was an early member of the PS Audio Forum’s Matrix Owners Club. But, as Groucho Marx wrote in his letter of resignation to the Friars’ Club, "I don’t want to belong to any club that would accept me as one of its members.” 
In all seriousness, the Matrix is tremendous and I found it to be essential for getting the most out of the DS Sr. DAC in my system. But with my plan to sell the DS Sr., the Matrix and UpTone PSU became expendable. I wanted them to go to someone who would put them to good use rather than have them collecting dust at Chez Bootzilla.
Thanks very much for the lead on a possible Aries G2 purchaser. I will PM you if I decide to sell it.
