I just bought one to replace an ARC PH-1. The PH-1 was available at the time I found a used ARC LS-22 and needed a phono stage. Just before the end of the year, I came across a deal from A/V Logic in Des Moines, IA. They claim to be the largest Pass dealer in the country and got the following deal.
When Pass recently upgraded the cosmetics of the units, they had some of the old power supply boxes left over. They let A/V Logic sell these units with the cosmetically upgraded control box (silver sides). All electronics I'm told are identical. The Xono is reviewed by Anthony Cordesman in Issue 128 (Feb/Mar 2001). It's listed as a Class A unit in Stereophile's Oct 2002 issue.
A/V Logic's deal was $2400 (vs $4200 for the new cosmetics). It was shipped just as described directly from the factory in California. I just checked their site and the offer is still open. (http://www.audiovideologic.com/)
What a spectacular difference, even with only a Benz Glider. The Glider is in a Graham 1.5 on a VPI MkIV and is on the way out in favor of something better suited to the rest of my analog chain. It's one of the quietest phono units available, both reviews say so and I can attest. It has practically infinite adjustment possibilities for cartridge matching via dip switches accessable through the top. GO FOR IT.
