A good friend owned a Graaf OTL for quite a few years.

It was only sold as they were never quite sure about it, as it run so hot.

I would like to think Graaf and Atma-Sphere have a parity in reputation when it comes to reputation for having a reliability.

'HOT' is the Key Word, and Hot combined with a Domestic Environment is a combination that is for the best, if it comes with a cautionary advisory. I have taken that advice in relation to OTLs in use as Amplifiers in a Home System.

My friend with the Graaf had purchased this as a retirement gift.

After a period of usage, they had made it known, they were not able to fully rest and enjoy the music, as they had with other owned Amp's. There was always a proportion of thought reserved for the concern for the Amplification running quite Hot. I have not been informed of any concerns about the usage of an Amplifier since they separated from the Graaf.

If it led to this degree of concern and angst, then their decision to replace the Graaf was wise. Why own something if you can’t relax with it and trust it?

My sharing an experience around the subject of OTL Amp usage and the sharing of the experience of a friend, has content that is not unfamiliar.

It would be quite easy to discover these are concerns that arise in other discussions that are aired in a thread to be found on other forums about the usage of a OTL Amplifier.

Such concerns can be found within this very forum. 

Has it occured that I am not discussing a power amplifier on this thread? Doh!
