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.

P.S. I am interested in hearing about good experiences as well as nad re reliability and sonics.

Thanks
I have had only one pilot error problem (my fault) with Aesthetix Io (volume conrols) in two plus years of very continous use. Jim White has been fantastic with responding to my needs. I had the second power supply added to my unit and WOW that makes the music performance even better.
Hi Gerry,

How many times have you had to change tubes in those two years? What is a pilot error problem?

Thanks,

Pilot error problem. Now I get it! . Still, I would like to know about the number of tube changes.
Hi Gerry,
Now I come in with questions too:
1. Tube changes?
2. Did you keep the original brands?
3. What is a "second power supply" ? An upgrade or beefed up version or are you cascading them in a way unsing two supplies, which to me seems unlikely, though.
