A lot of sketchy reviews online about the software on this unit, but as of late 2022 it seems like Arcam ironed out a lot of the bugs. There is an Arcam SA30 forum on Discourse that is very helpful if you run into any issues.. fortunately i didnt have any. You need a computer or laptop to get the latest firmware updated, which you will want to do as soon as you pull it out of the box. The unit may be a little plain looking but i feel it is of solid quality..well made and heavy. It does have plenty of power, my speakers get down a little below 4ohms at times and this amp has no issues pushing them at loud volumes. My speakers have a sensitivity rating of around 86db and i have yet to go past vol-40 out of max vol-99. Remote is decent, can be programmed to control just about any type of home audio/TV equipment. Hdmi E-arc works perfect, i can control the Arcam's volume with my Firestick remote if i wish. The internal streamer sounds good, ive had or have a Node, Cambridge CXN2, Ifi Zen Stream, and a WiiM mini. On Sound quality alone I'd say the Zen is the best of those mentioned..the Arcam is just as good or better. The Arcam Musiclife streaming app is worthless in my opinion, I'd keep the SA30 wired with the Lan/Ethernet port and use Tidal connect app or Quboz or whatever your choice thru Mconnect, Upnp, or whichever app you like. Although a great feature with this amp is Chromecast built in and AirPlay. You can basically stream whatever you want to it. I have yet to use the Phono input but ive read other user reviews that had nothing negative to say about it, all positive. So how does it sound? Initially i was not impressed, but after about 5 days of this i decided to reboot the Firmware. I told myself there is no way this amp sounds like this and gets all these great reviews for sound. I was right, i basically reset the amp and forced it to reboot the latest firmware and the amp came alive. I would say it is very clean, clear, transparent, neutral. Not overly warm or rounded like a tube but not cold and thin either. Its nice sounding, the amp is in control of the woofer, quick with nice bass and a soft but detailed treble range. I feel this amp could push most speakers, it does have a preout if you needed more power for some reason but i use the preouts for a subwoofer. No tone controls or Bass management like you find on most AVR's but it has Dirac Live. Take your time setting it up, look at youtube video's..get yourself a microphone boom stand, take your time and you will be rewarded. With Dirac you can basically set the tone to your liking while smoothing everything out..less resonance and tighter bass. If you are in the market for an all in one music box with Dirac this unit is worth a try. Its a little pricey but atleast Arcam has fixed most of the issues it once had. Its a very neutral amp, what you put in is what it puts out. When i compared the Arcam's internal dac to my $1k RME dac i couldnt hear much of a difference. So one is getting a better than average dac, better than average streamer, phono input, Hdmi, and a very good amplifier with good power and able to handle low ohm/sensitivity speakers. Pre-out for sub and Dirac to smooth it all out. This unit checks a lot of boxes, but you need to be able to update firmware if necessary, navigate Dirac on a separate computer to load it up initially, and see if Arcam produces the type of sound you are looking for. Good luck on your journey.
