Aesthetix Io-Reliability Problems???

I have heard recently from several sources that the Aesthetix Io phono stage has reliability problems and that it runs through tubes very quickly. What has been the experience of Aesthetix Io owners? What types of failures have occured? Are there any non-owners who know the details of the problems? Since I am interested in the Aesthetix Callisto linestage, which is much simpler and carries fewer tubes, I would like to know if the problems with the Io extend to the Callisto as well. Thanks in advance very much for your help.

Albert Porter has immense experience with the IO and Callisto. I know he has experimented with many varieties of glass. Hopefully, he will share his wisdom.

Gerrym5: It is endlessly refreshing to encounter people like you and Albert Porter (and many others on this site) who are not only dedicated and humble audiophiles, but are genuinely sincere and generous with their long-accumulated knowledege. This is an infrequently-acknowleged aspect of the hobby that gives me (and, I surmise, many others) great pride. While I do not have your skills, I certainly try to reciprocate all the pearls. A heartfelt THANK YOU to all of your ilk!

Albert: I'm awed by your generosity re: the above IO post. I do not wish to drain any more of your time, either. One question: I'm curious to know what were the sound benefits in adding the 2nd power supply to the IO and Callisto? Were they very significant? Remember most of us have Mickey-Mouse gear compared to you (no offence to others intended!), so I wonder whether the power modifications would be that significant on lower-priced gear (yeah, I'm aware that bucks do not a great system make).
