Aria has almost the same looking as KXXS or Starfield! You may also wonder why MOONDROP uses the same naming as its predecessor, is it the same tuning and just different looking? Absolutely not! Not only the looking but the tuning are absolutely different! Generally, we don't recommend customers to purchase blindly, but Aria, with such excellent workmanship and at this price tag of US$79.99, can be blindly owned! Of course, the reviews would come out soon.

SMSL updated two new ones into their catalog, the above-mentioned DA-9, and this flagship priced US$659.99, A1! A1 adopts a classical FET Class A amplifier circuit to provide better high frequency and feedback loop stability. It makes the transistor always work in the linear region, so the Class A power amplifier has almost no distortion, other than these advantages, the Class A amplifier is easy to construct with a single-device component and minimum parts count. This means then that the Class A Amplifier configuration is the ideal operating mode, which can provide a very smooth sound quality, a soft and warm tone, and ethereal treble. The users who have used their flagship P1 amplifier and D1 DAC know that SMSL's flagships perform beyond our imagination, so let's take a look at how unexpected A1 will bring us!

As always, read some parameters of A1:
Use high- quality components:
1.The front stage adopts parallel stabilized power supply
2.Low distortion, high precision, Volume control chip PGA2311
3.Imported Porcupine Power Transformer
4. High-quality audio socket imported from Japan
Powerful driving force:
Adapt to most speakers on the market, Powerful driving force, proper magnification and precise volume control make A1 can match most of the desktop small bookshelf boxes and most of the earphones and earplugs on the market, and adjust (for specific gameplay, please scan the code and refer to the official account article to Satisfactory timbre.

I'd challenge that.

They've listed a power rating at 32ohm so I suspect they anticipate some users using it to drive the likes of an Abyss TC or Susvara.

I also think the rear headphone output is a poor design choice. Its a pitty it doesn't have balanced XLR inputs.

DA-9 is an interesting amp. Plenty powerful and clean. As you'd expect a chip amp to be it is also a bit flat/sharp. Not warm or 'full of life' but it is a perfectly reliable (I'd assume) power amp for HTPC purposes. Very good for gaming, where I prefer less warmth.

Now on to the most important part.. the old DA-8 is a LOT warmer (Not s, I didn't like the s) in operating temp.The DA-9 runs STONE COLD in operation and still has an internal supply which is fantastic. There is one glaring feature missing though, sub out volume level adjustment. I'd have loved this feature.

I plan to give this a go in my main system, however I doubt it'll mesh well as my modded Akitika mitigates the forward nature of LS50 nicely. We'll see, maybe I'll be surprised. For the money and those hunting for neutral, the DA-9 is a slammer.

I'm also looking at the SMSL DA-9 to replace/upgrade my DA-8s. On my DA-8s I replaced the factory chip ceramic glue with something that is capable of high processing CPU's that generate much more heat which in turn made my unit run stone cold. I NEVER turn my class-D amplifiers off as they draw little to no current.

The one thing that is keeping me from pulling the trigger is that the DA-9's display cannot be turned all the way off. I hope this is something that S.M.S.L will address through a firmware update as there is no reason for OLED screens to be running unless you want them to fail before the rest of the amplifier does. Also, it's distracting to me to have extra lighting if it's not an Analogue VU meter. I hope they realise that not everyone wants the screen to be simply dimmable, it's only one more step to turn it off entirely.

I'll probably purchase the DA-9 regardless, though no doubt in 6 months to a year, there'll be an even better version by then.

Thanks for your kind feedback, I'll phrase it to SMSL. Thanks again. Of course, we'd love to hear more feedback after you get DA-9.

The 8s never ran warm for me, so I never attempted anything with it.

I posted on SMSL official's twitter account that I just placed my order for the DA-9. I am looking forward to it. I hope you can get SMSL to allow for turning off the screen all the way like the DA-8s could!

Mine never, ever was turned off except for upgrading the thermal paste. Mine runs cooler to the touch than my audio rack made of HDF or room temp. It's not a risky operation, the amplifier and chip is very easily accessible but I wouldn't recommend it as you'd void any warranty. There was zero difference to sound quality/noise. So it was a precautionary measure.

The variable sub-out should be something relatively easy to fix with a firmware update. Let's hope that they do this. Though my powered sub does have front panel controls, it's a little bit out of the way to reach. I'm looking forward to receiving mine as I just placed my order. Maybe there'll be a V2 later on, I'll buy that too. I like the fact that SMSL continues to improve with each generation. As for the amplifier sounding cool, the DA-8 was ICEPower and frankly it's a very, very old design. That amplifier board has been in so many products that i can remember having the same amplifier board in a TEAC amplifier in 2008. I would suggest changing cables to see what that brings to the table. You might find a cable that offers a richer sound. Not so much the speaker cables, but the interconnects. Speaker cable can get very costly. I have original western electric cotton sleeved twisted 16 gauge speaker cable and also NORDOST cable for my speakers. They have their merits. Cables do not all sound the same. Kimber Kable used to use a dye for their wire that really inhibited the sound after a week of use, they acknowledged this and went to a clear PET sleeve/jacket for their wires. The black and brown was a rubber material. The actual wire itself was the same.

I'm using very nice wire. My comparisons are to a well modified Akitika GT-102 with the likes of Pulsar CUii internal wiring, etc. I still prefer the GT-102 to the DA-9, but like the 9 very much for what it is.
