If anyone decides to sell their ps100 power supply please PM me.

How's the noise floor of this with the stock opamps + PS100Pro ?
I'm considering buying it to use with my Hiby R6 Pro II (if anyone ever tested this combination I would apreciate some insight too).
Although I don't particulary intent on using the A100TB with my very sensitive SoundRhyme SR8, as I would likely use the unit with some earbuds and more high impedance IEMs I plan to get in near future, I would wish to see the performance on my SR8. Has anyone here tested the stock opamps with super sensitives IEMs like the SR8 or even the Andromeda ?
What about earbuds ? I have a TGXEar Sunniva and although I love the sound of them, I find it very lacklustering on just the R6 Pro II alone, especially in comparison to my YULONG Aurora. Is the A100TB able to drive Earbuds (180omh+ impedance ones) with ease ?
I was looking for PA10 from A&K too, but I found some postings stating that this would be much better, and as I don't plan to buying a new DAP anytime soon, I want to get an amp that is on the same level as the R6P2. I wouldn't be missing the Class-A amp from the PA10 I assume, right ? And this has the same black background as PA10 ?

Sorry for so many questions, but as that would be my first portable amp, I really would like to know more before making any decisions.

There is no background noise, absolute black.
I can't give you any indications with headphones, but with IEMs the performances that the A100TB + PS100pro can give are of an incredible level, and therefore your DAP will also benefit greatly

Great combo.

Great combo.

Is that SS3602 ? What you use for input gain ?
I also use SS3602 for voltage gain

Well, it's there in the photo, but you can't see it, it's inside and I use it for input gain.

What you see in the photo is the Sonic Imagery Labs 994. It is used for voltage gain.

And this is only one of the possible options, but I don't use this combination very often.

Mostly I use SS3602 for input gain. Options are also possible - OPA2111km + SS3602, if you need something compact. Also SS3602 + SS2590 Pro or SS3602 + Staccato OSH for desktop use. Both combinations are great.

I also sometimes pair the SS3602 with an Alfa AS402 or occasionally a Burson V6 Vivid. However, I prefer the combination with the Alfa AS402 in the input gain and the mentioned Staccato or SS2590 Pro in the voltage gain.

Although I doubt it, can I use this adapter to connect Hugo 2 audio output as a source to the A100TB "true balanced" amplifier input (4.4mm)?

Thanks.

Get you! I think I will try the Ss2590 pro for the output gain and Alfra AS402 and the sonice image. Have you tried to remove the battery from A100TB? It seems mine stuck inside. Can't be removed. I want to make more room for the op amps

I did not try to remove the battery from the amp. For the A100, there is enough space to accommodate two amplifiers, if you take into account the possibility of placement at different heights, etc.

Is the Burson V5i in the input stage, more appropriate consideing resolution, stage and dynamic?

BTW, should it be the V5i or the V5i-d?

Thanks

Managed to connect Hugo2 SE output to A100TB balanced input with very good results, see following connections with the cables I had at hand:
- Hugo2 SE 3.5mm output
- 3.5mm male to 3.5mm male interconnect cable by Audioquest
- 3.5mm female to 3.5mm female adapter
- 3.5mm male to 4.4mm female interconnect short cable by Nicehk
- 4.4mm male to 4.4mm male 5pole interconnect short cable by iFi
- A100TB balanced input

Sounds great, no issue.

Want to enhance the A100TB.
I want to swap the preliminary stage OPAMPS to Burson V5i.

1. Should I buy two V5i or one or two V5di?

2. Which are the two preliminary opamps? Those close to the dip swithes or those close to the output four transistors?

Please advice.

Thanks

As an upgrade for my A100TB, I decided to try the opamps too, and I ordered a pair of Burson V5i Dual and a pair of Burson V6 Vivid.
I'm curious to hear what change will be in the already fantastic sound that my A100TB can give me
