Pass Labs XA25


While reading the 6moons reviews from 2018 and 2023, I noticed in the pictures from the 2023 review the XA25 has what looks like a small transformer (I may be wrong) mounted to a circuit board. I don’t see this transformer in the pictures from 2018. Does anyone know what’s the purpose of this transformer?

I think the First Watt stuff is cool, but the XA-25 (note that like the First Watt stuff it's utterly unique in its design...especially compared to any other Pass amp) and my Had amp cover my bases so well I'm unlikely to spend another 5 grand or so out of curiosity (also, I don't want the other amps to become jealous...they have feelings after all). If I didn't have a Pass already I'd certainly try a First Watt as everything about 'em makes sense. If anybody wants to loan me one I'll pay shipping. Nice of me right?

 

Anybody notice that recently Pass has run full page adds for the XA-25 in major gear magazines? Maybe they have a surplus of 'em or something but the wait for shipping makes that seem unlikely. It's all good as some feel it's the best amp Pass makes (doubtful, but it makes me feel "special"). 

While watching the Absolute Sound tour of Pass Labs they showed an interior shot of the XA25 and I observed a Tamura 3FD-320 transformer mounted to the circuit board. I googled the purpose of the transformer.

 

The Tamura 3FD-320 transformer is typically used in high-end audio applications to provide isolation and improve sound quality by reducing noise and distortion. It helps in converting voltage levels while maintaining audio fidelity, making it suitable for high-performance audio equipment.

My XA25 arrived and after listening to it for almost 2 weeks it’s just not the amp I want in my main system. It’s ok, but to me it doesn’t live up to all the hype. I’ve read where a lot of people love this amp but not me. I’ll keep it but it’ll be in my bedroom system.
