SMSL PA-X Gallium Nitride Power Amplifier - Now on Apos

[Apos Audio]

Hi all,

We are big fans of the new SMSL PA-X—a no-frills, high-performance power amp with Gallium Nitride transistors that deliver cleaner, faster, and more detailed sound than your average silicon-based gear. It’s compact, dead quiet, and ridiculously efficient, with up to 500W of output in mono mode. It’s a great daily driving for a living room setup or as a pair of mono blocks in a serious 2-channel rig. Balanced and unbalanced inputs, a remote, and a front volume knob—$699.

Really looking forward to some impressions/reviews on this !

Thinking of replacing my Denon PMA-800NE with this to use it with a true balanced DAC, since the Denon only has RCA inputs...

Same here, looking forward to reviews, I'd also like to know if these will have swappable op-amps?

@Apos Audio
Again, why are there no reviews to find anywhere on the SMSL GaNFET amps?

And don't send them to ASR or other measurement freaks. They will only break your samples with torture tests and have no idea about actual sound quality.

Hi there,

There are reviews coming out. However, most reviewers are currently facing a packed review pipeline due to the numerous launches happening this time of the year, so they may not have gotten to the product yet. - John
