5.0 out of 5 stars Pretty good headphone amp
Reviewed in the United States on 1 November 2023

This is a recommended buy from me. I'm talking about the SMSL HO200. Basically everything on this amp functions well and provides clean, clear and detailed sound. The break-in period was about 24-48 hours of power-on time. The sound improved substantially over the break-in period. Solid state amps are great for people who are busy or are doing multiple things at a time during the day. I was always of the opinion that when it comes to hi-fi gear you don't need to spend a lot of money on a amp to get good sound. This amp proves my opinion another time. I purchased this because I had a headphone amp completely break on me which was a tube amp. Tube amps, by comparison, can't be left on all the time and require maintenance and replacement tubes. When that tube amp broke I just threw it away rather than have it repaired and looked for a solid state solution. This SMSL HO200 makes the music listening experience really laid back and enjoyable. I am using the XLR inputs from my Eversolo A6. Sounds great to me with this combination. The only thing this unit needs is for the manufacturer so spend some more money getting the toggle switches and volume potentiometer to feel a little bit more rugged and solid. Otherwise it's a great amp I intend to keep for the long haul. Thanks for SMSL for making a great amp. My headphones are the DCA Aeon RT CB. This amp can drive them no problem. I prefer the low gain setting around 11-12 o'clock.

I bought the HO200 to drive my new HIFIman Arya in combo with my smsl DO200 MKii. That I already use with my KALI lp-6v2(powered studio monitor). When I receive it, I was absolutely blown by the sound it gives to my Arya (and my friends who own some expensive European gear too!!). But it is not finished. After a couple of days, I've try to pass my speaker true the full balanced preamp function of the HO200 and it finally eliminate the annoying tiny white noise I 'got on my speaker from my pc. The other thing I think is really really nice, is the quality of the switch with their "no-impact sound design". It is completely got rid of the pop you can get when switching input or output. So, you can stop worrying damaging your precious gear by inattention.
So, yes i strongly recommend this product (and the pairing with the smsl DO200 MKii)

All the input and output options you could want. Amp has ample power to drive Abyss 1266 and a set of Hifiman Egg's with ease. I've even tried a set of 600ohm headphones on non-balanced output and it has enough bang to send your ear drums into orbit. No static hiss, lovely switch gear and finish. At this price range, you couldn't ask for more really!
