Hi Alex .. Thanks for your informative review on dh1000 , need ur view on below 2 ques.
1.) My current source is Xduoo x3ii (AK4490 DAC) and if add dh1000 in this chain to drive low impedance iem's (16 to 32 ohm) what is SQ improvement i can expect ? .. No cans only iem's
2.) if you have to choose only 1 iem to pair with dh1000 which one will it be ? Preferably under 150usd

1. Can't really answer your question cause I don't have Xduoo to compare with. But I can tell you that there might be improvement in channel separation and driving ability with DH1000 due to it's double DAC & AMP design
2. I don't have lots of different IEMs but from those that I have - I prefer 2.5mm balanced Hidizs Seeds due to gentle and detailed feel of the sound.

Hi,

Tempotec Sonata iDSD Plus is in my opinion the same product and it is available on Aliexpress for only 99$.

I just ordered one and will report once it is landed.

Hi von .. do you have the dh1000 amp as well ? To make a A2B comparison with idsd plus .. i understand both share the same internal chipset .. but don know about their tuning and choice of materials of PCB and connectors

The seller has confirmed that the devices are 100% identical.
It is apparently a coorperation.
Tempotec has done the engineering of the board, hidizs the case.

I am actually reviewing Tempotec Serenate iDSD, which is the desktop thingy, and it is also marketed and sold by HIDIZS, on their site, so indeed, they are good friends with Tempotec

Is this mfi certified?

Is the battery easy to replace with a little soldering without deconstructing the whole thing? It lives and dies by it's battery so important fact I think.

Not very easy but doable. You would have to heat up the glue, remove the glass and replace the battery. it is on JST plug. No soldering. Picture is taken from FB (by Muises Cardona)

I haven't replaced the battery, because I don't want to damage the board or the battery itself, since it's glued, but I've been able to use a 3.7V 2000mAh battery from Sparkfun. I don't charge that battery with the DH1000 because it may damage it since that one is 3.8V and the one I got is 3.7V. Also, because my unit charges the battery very slow, at a rate of just 0.06A-0.08A, I also got a basic LiPo/Li-Ion charger which does works with the 3.8V battery.

Unfortunately, my unit is bad regarding the charging circuit and suddenly stops working at about 400mAh of battery usage, but the sound circuit works and that's the most important part for me. It can be turned on without the charging cable and then it can be attached so that it uses power from both USB + Battery (USB is capped at 0.12A in my unit).

Some more pictures of it:

I can't seem to connect my V20 / iPhone through the USB-A Port, it charge my phone's battery for a second then shut it off immidiately.

Do you have the blue LED problem? Mine does the same. Defective circuit, unfortunately. However, I can still use it via the Micro USB port.

My micro USB port works fine, when i connect to the USB-A the Led turn red then shut off. One time it work is when i fully charged both devices.

That USB-A port lso acts as a battery bank, so it may be related to the DH1000 charge as it will discharge faster with that port. It is also stated in the manual. If the battery is not fully charged then it may turn off. That explains why it works if it is charged.
