It looks like the SMSL DA-8S but with better THD+N/SNR, a better screen and a subwoofer out. The amp power looks to be the same though
What's the DAC in this - it receives BT? (I'm assuming it must have a DAC?)
If you read the page it will actually tell you so you do not have to assume!
The DAC function is built into the BT receiver module. However, the type of receiving module used has not been announced.What's the DAC in this - it receives BT? (I'm assuming it must have a DAC?)
BT is normally output as an analog signal from the receiving module, but it can also be output as an I2S digital signal and can be input to the DAC chip of the ESS9038Pro.Thanks, I read it but it's confusing or I don't understand what they're saying..... That BT has its own circuitry?
I have an SMSL su9 - it has BT but it also has an ess dac..,.. So does that mean my su9 doesn't use the ess dac when it's receiving bt??
I received word from their technician. The graph on the website is indeed the 8 ohm graph. The THD at max power into 8 ohm is 0.002% and can be done with RCA at 2v or XLR at 4v so there's isn't a direct need to use a DAC with higher voltage like some other amps to get fully rated power. I think I will go ahead and take the plunge since I already have the SU-9 and SH-9. I will measure the voltage out myself once I get it though I won't be able to prove THD or anything.
Edit: Bought it from ShenZhen instead of Apos since I couldn't get them to reply to me for over a week which was a stark difference from when I bought the SMSL stack and a pair of Ananda from them.
One thing to keep in mind is that it was measured with one chip into two channels. From what I understand, they are essentially bridging each channel so it is similar to having a bridged stereo amplifier per channel. On some products like the NAD C328 Amir measured, I think that went from 80w to 260W. There are similar trends in other speaker amplifiers. I don't think it is too much of a stretch to think they got a little over double the power when doubling the amplifiers and bridging them. Plus they did publish a power graph. The only thing I would worry too much about would be the voltage in. Mine comes in Friday so we will measure the voltage then.So the 90w into 4 ohm / 50w into 8 ohm power rating is likely close to being real/legitimate? The addition of a second chip (and the MEAN WELL power supply) has that big of an impact on power compared to the DA-8S or the Loxjie A-30, which Amir measured here as 40w into 4 ohm and 18w into 8 ohm?
It stacks very nicely with my other SMSL-9 series so it seems a worthwhile buy, especially if you have the SU-9 and SH-9 already. I might go with a spread instead of a stack. I need to get another balanced DAC though because I want my EQ set on a per device thing and having two SU-9 would make controls awkward.
It depends what you mean by compete. The Hypex would no doubt measure better and have more power. It also costs more though. If I could choose either for free, I'd choose the Hypex. Your speakers aren't very sensitive, but if you are in a small room, I'd guess the SMSL would be fine. It'd be more powerful than the A30. I use the (similar to A30) SMSL DA-8S with 89db speakers (6 ohm) and don't feel any need to upgrade, but I don't play at rock concert levels.
I wonder about this as well, hopefully someone here could get the unit and measure its actual power.Thanks for your response, RikB. If I’m understanding correctly, then if the DA-9 measures close to spec (and it appears as if it would), then the DA-9 is providing 90w into 4 ohm and 50w into 8 ohm, while the Hypex provides 103w into 4 ohm and 55w into 8 ohm, per Amir’s measurements? Is that a fair power comparison or is the Hypex actually more powerful than that in comparison? Not sure if the DA-9 power spec is at a higher distortion level and so to get a fairer comparison to the Hypex would have to allow for a higher level of distortion? I understand that the Hypex is more powerful, just trying to better understand by how much (and I’m a bit new to this).
