If a key requirement for your enjoyment is "dead silence" from the electronics, the Io will likely never satisfy your need. It is generating 80db of gain all from tubes. There are tradeoffs in doing this as compared to a solid state phono stage or a tube phono stage that uses a transformer gain step up device.
To my ear, the Io's all active tube gain sonics are consistently superior in naturalness, timbre and micro-dynamics - a sense of "life" to the music.
The downside to this all active tube gain is that a certain amount of tube rush is going to show through if you are using a very low output cartridge or if you are consistently playing at very high volume levels. The demand on the first gain stage tubes for low noise is significant and not to be underestimated. Even with "perfect" tubes, some people will continue to complain that the unit is noisy. For me, this is NOT the case. But, I've listened to vinyl and tubes for 40 years and am somewhat less concerned about dead silence in the background than others may be.
As to expressed reservations about soundstaging and precise imaging, I find no fault and only praise for the Io in these areas. I listen primarily to classical (orchestral and chamber) and small ensemble jazz. The ability to precisely and accurately reproduce the players and their instruments in space (horizontal, vertical and in depth) are high priorities for my listening enjoyment. And the Io is able to meet my very high expectations in these areas.
