[please forgive my poor English]
To sum up what I've read in various threads and on the Dutch HiFi-advice website's
Comments section, in which Aries Cerat's designer Stavros Danos himself replied and brought clarification:
- the manual says: "it is advised to avoid frequent on-off switching of the unit to preserve tube life" (
even if there are three chokes in the Incito (S), one for each tube).
- nevertheless, "2-3 on-off power cycles a day" is not considered as
frequent [says Stavros].
- for instance, turning
on the gear before a listening session and
off after the last listening session, is fine. (During the weekends, this could go up to 12 hours
on, but it is still much better than 24/7.)
You can find
DETAILS and Stavros Danos' answer here (on that site, each reply has its own link, so you have to start with my question first; then scroll down to Stavros' reply then to the Dutch AC distributor's reply afterwards;
his name is Ron too):
