Paul Speltz Zero-Box Autoformer With Tenor OTL

Hello everyone,

is there anyone using Paul Speltz Zero-Box Autoformer with Tenor OTL and can give a full user experience please? My concern is whether the PS Zero Autoformer will degrade the extreme frequency of what the tenor the best for.

The speaker by now with the Tenor is Rockport Antares.

Thanks in advance for all the input.
