I owned the Pass Aleph Ono and upgraded it to the Xono. The latter is quieter (seperate power supply) with deeper, tighter bass and can resolve details slightly better. It is very neutral and has huge gain and very adjustable loading. It is also less tall than the Ono. Maybe 4 inches. It can be found for about $2000 used and is an excellent value.
Perhaps Audiofeil can tell you about the new Pass XP15 which will be less expensive than the now discontinued Xono was when new and perhaps even better.
