    @Vtory The Hexfred SS rectifier is partly to blame for a bit of the roughness. I didn’t want to have to purchase rectifiers on top of other tubes but the Apex Teton has shown me that the rectifiers also add to the whole of the sound. I’ll need to ask the other owners who have tube rectifiers if they still perceive that roughness you hear. But yes, what you described has been there since day one with the amp. As much as I love the amp I would of also preferred to go without the stepped attenuators. Never thought that not being able to do very small incremental changes on the dial would be such a pain. Thanks for the review!

    Interesting. I thought hexfred a better and less harsh alternative to diodes -- and I am almost a noob to tube rectifiers lol. If rectifier tubes address gotl's drawbacks to some extent, this amp can be much easier recommendation.

    I am also interested with what would happen if similar gain stages paired with transformer-coupled output stages, as I have been a big fan of OTP in general. Considering Glenn amps' bespoken nature, I bet such configuration possible.
