If i leave my PC desk very fast the music stops for like 3 seconds, it is very weird. It only happens when i leave very fast and not all the time.

Are you using USB or Coax input?

Hi guys , I have a question about the SMSL RAW-HA1 amplifier, what is the filter section for in the amplifier settings and what does it change in terms of sound ? And if I don't want to use these filters, what option should I set this filter to ? Thanks guys .

Non over sampling is in my opinion the best choice for a more natural less processed sound. It usually allows the better soundstage too.

Ok , thank you very much !!!

Ok , thank you very much !!!

If you have the amp now then over the first couple of months your ears will pick up on the differences between the filters if you have normal hearing. I found filter 2 and 6 somewhat preferred after a couple of weeks but filter 6 almost instantly on my SMSL AO-300, 6 is Non Over Sampling. I also prefer Non Over Sampling (NOS) on Fiio’s products too.

Thank you very much for your reply, I don't have this amplifier yet but I'm going to buy it soon and I wanted to know what this filter was for before buying it, thanks again.

Here is another one, but this time sans DAC.
SMSL PA 40.

The style and dimensions seem to be intended for use with the DO100 pro DAC.

ASR testing and review is up;

Shenzhen/SMSL RAW-HA1 Amplifier Review

This is a review and detailed measurements of the Shenzhenaudio SMSL HAW-RA1 integrated amplifier with DAC and headphone output. It was sent to me by the Shenzhenaudio and is on sale for US $212.49. The user interface is much updated and more elegant than the older SMSL UI. It is easy to use...

Very, very similar to the Loxjie A40

Same Infineon-MA5332MS Integrated Class D Amplifier
Same CS43131 headphone amp
Same NJW1194 electronic volume & tone control
Same XMOS XU-316 USB receiver

Do these designs sprout from one and the same company and simply be rebranded/licensed to different companies ?
Or is it simply copying a lot from each other

SMSL seems to never connect the ground terminal on their amps, which can lead to a tingling sensation when you touch the enclosure while standing on the ground barefooted.

It's probably Class II and it doesn't require chassis to be grounded, mostly because the AC-DC power supply is isolated. More details could be read here: https://en.wikipedia.org/wiki/Appliance_classes.

Someone with the RAW-HA1 can try to use the HDMI(ARC) in? Does it turn on/off with TV, change volume with TV's remote control and have support for CEC?

cec is not working, volume is working but in some sort. the amp volume stay fix but on tv you can low the volume. something like signal volume.

Thanks for the reply. It's a shame because reading on this forum the AO300 also had this problem. I thought they would add these features with this new product.

 

[feromir]

So, look at RAW-HA1 as a mere design variation of the AO200/AO300 amplifier lineup. However, I still do not understand the logic behind phasing out the balanced input option from amplifiers following the SMSL AO200 model while the matching DACs do have balanced output.

I just gotten my Loxjie A40 less than 1 week.......

Was deciding betwen SMSL AO300 or Loxjie A40 and gotten the A40.

Now smsl just released this Raw-HA1. Sure outlook this HA1 look nicer than A40 to me. HA1 LCD also looks better too.

Also just compared spec for spec. Both A40 and HA1 have very very similar spec and parts. Just A40 have the phono input which HA1 dont have.

Anyway SMSL and Loxjie are related and are sister company.
