Best 845 amp?

Hello
Looking for a inexpensive 845 amp.Not familiar with Caztech. Info available is non existant. Manufacturer no longer in business.
It would be a true leap of faith for me to purchase one now for sale in my area.
Could I impose upon you to give your experience and if possible how you would rate it vs other 845 amps you may be familiar with.

Kind regards

Audion Black Shadow mono pair. Right behind that, the Sophia 845 mono pair. Both are SET. I make it a point to seek better 845 amps, having heard and spent time with every alternative discussed here, plus some that aren't mentioned. Nothing so far has matched the speed, tonal integrity, neutrality and dynamic clarity of the Audion monoblocks, with the Sophia approaching closest.

The new Shuguang Psvane 845 PSET monoblocks look promising but haven't heard them yet on speakers sufficient for evaluating them seriously.

Phil, Is the Audion still your favorite amp with the Zu speakers? Scott
