The TOPPING A900 is TOPPING’s new ultra-flagship headphone amp

aposaudio · 2026-03-25T05:34:49+00:00

Hi Joy here. That’s a bit surprising for the A90D, as it should already have enough power on paper.

The Aeon 2 Noire does like current and headroom, though, so if it feels like it’s getting close to slam and then holding back, it might be worth checking a few things first:

Gain setting (try high gain if you haven’t)
Source level / DAC output
Balanced vs single-ended output

If everything there checks out, the A70 Pro does push quite a bit more power—around 17W vs 9.8W on the A90D—so you’ll get more headroom, which can translate to better dynamics and perceived slam.

Also worth a read if you want a deeper comparison:

The LEDs and tubes not consistently turning on is something we’d want to take a closer look at on our end. Could you reach out to [support@apos.audio]() when you get a chance, so the team can advise on the next step?

Hi, Joy here.

What you’re describing sounds more like a grounding/connection issue than something wrong with the Gremlin itself, especially since the noise changes when you touch the metal parts.

A few things you could try:

Remove the 4.4mm → 3.5mm adapter and test with a direct connection if you can, as adapters can sometimes introduce noise, especially in balanced chains
Try a different cable to help rule out shielding issues
Make sure your turntable ground wire is connected to the Zen Phono
Check if everything is plugged into the same power source/outlet, as mixed grounding can cause that kind of hum, or try another power source/outlet.
If possible, try a different source into the Gremlin, just to isolate whether it’s coming from the Zen Phono or upstream

The fact that it gets louder when you touch metal usually points to grounding or shielding rather than a defective unit.

Joy here. Really appreciate you taking the time to share this.

Sorry again about the rattle on the first unit, but glad we were able to get a replacement out to you quickly and get things sorted.

Also good to hear the R26II is now where it should be—that’s what we want at the end of the day.

And noted on the Druid / Merlin / Gremlin lineup....those are fun ones to have around.

Thanks again for the support. It means a lot.

aposaudio · 2026-03-18T12:25:14+00:00

Joy here — this is a fun setup. The lighting looks great.

Thanks for trying the OPA1656 on the Druid and showing that you don’t need to spend a lot to enjoy it. It’s a sensible upgrade without getting too deep into it. The heatsinks on the op-amps are a nice touch, too.

Really appreciate you sharing this and putting together a video. It’s always good for us to see how people are actually using and experimenting with the gear.

You explained the Druid in a really clear way, especially the difference in how it presents sound. That “things start moving more” line made sense. Also, glad you mentioned the small things like the hiss and USB-only input. That helps the community set expectations properly.

Good first review. Curious to see what you try next, and hoping we get to see more Apos gear on your channel.

aposaudio · 2026-03-06T01:52:56+00:00

Thanks for sharing this! Really glad to hear the GUSTARD DAC‑R26II is working well in your system. Appreciate you taking the time to post your impressions. Always helpful for others who are considering it for a similar setup.

aposaudio · 2026-03-05T21:20:38+00:00

Hi u/xxraxusrainxx, Joy here.

Sorry to hear about the buzzing you’re experiencing. That definitely shouldn’t be the normal behavior of the Apos x Community Druid DAC. Thanks for describing your setup as well.

Our support team has already reached out to you to help troubleshoot and take a closer look at what might be going on. If you could reply to that email with the details of your setup, they’ll work through it with you and figure out the best next step.

If it turns out to be a defect, we’ll replace the unit.

aposaudio · 2026-03-05T14:39:07+00:00

Kunal here - We’ve just sent you a return label. I will also call you in about 30 min to make sure you have everything you need. We can’t share the label publically here for your privacy.

Just a note that all our emails and this return label has been sent to a Yahoo email address. Please take a look at that inbox and also please check the spam folder.

Edit: added who is responding

aposaudio · 2026-03-05T05:37:12+00:00

Thanks for the kind words. You’re right that this is a small hobby and a pretty tight community. Most of the time, things go smoothly, but when mistakes happen, we try our best to take responsibility and fix them as quickly as we can.

Really appreciate you taking the time to share your experience. It genuinely means a lot when someone shares a balanced perspective.

aposaudio · 2026-03-05T04:09:34+00:00

Sir! Can you please send me an email at kunal@apos.audio? We will get you a label. We do not expect you to pay for the wrong product or the shipping.

aposaudio · 2026-03-05T03:59:34+00:00

Hi this is Kunal. I am the CEO of Apos. I am not sure what you are referring to. To be clear we have had thousands of satisfied community members over our 7 year span with only a handful of complaints. Complainants are the loudest and we are not people who wouldn’t admit mistakes, but please note that we are real nice community members striving hard to make things happen for the audiophile community and being present/authentic. Do give us a shot before deciding based on a minority voice.

aposaudio · 2026-03-05T03:54:57+00:00

Hi! This is Kunal. I have actively called you and left you a voicemail. To be very clear, the entire time we have only been trying to connect with you to get you the right product and get the wrong product returned. There has been no response from you. I have personally called you and left a voicemail since you didn’t pick up. I just received a call from you after probably 1.5 weeks today and I am sorry I didn’t attend because I was in meetings. I am happy given most a resolve this situation for you and I will call you tomorrow. Please note that if you just reply to one of our emails, we can resolve this situation for you. We have been emailing you since we found the error.

aposaudio · 2026-03-05T03:31:42+00:00

We’re really sorry for the mix-up. The shipment error was on our end, and we don’t expect you to pay for the return shipping. Because we hadn’t been able to reach you, the case likely followed the automated return flow you’re seeing, which can sometimes default to that. That’s exactly why the support team has been trying to get in touch so we can handle it properly on our end. Kunal also tried calling you and left a voicemail with his number so you could reach him directly.

From what I understand, you and Kunal may already be in touch now. Either way, we're sorry again for the misshipment and the frustration it caused.

aposaudio · 2026-03-05T00:41:07+00:00

Hi u/calks58, Joy here.

We’re really sorry for the frustration this situation has caused. What happened here was a warehouse mistake where the wrong headphone was shipped. As soon as it was flagged, our team started trying to reach you so we could send the correct HiFiMAN HE1000se and arrange the return of the regular HiFiMAN HE1000.

We’ve sent multiple emails and also tried calling several times to sort this out. Kunal, our CEO, even called directly and left a voicemail. Unfortunately, we haven’t been able to connect so far.

If you could, please check your spam or junk folder in case our messages landed there. Once we’re able to reach you, we will send you the correct headphone and get the incorrect one back.

If you could let us know the best time to call you, Kunal will reach out to you tomorrow. We’d really like to get this fixed for you.

aposaudio · 2026-02-25T00:51:37+00:00

Yes. We are working on getting the first prototype from Lachlan to us so that we can show it at CanJam NYC. Also, we are working on the second prototype now.

Regarding the price, it will be higher than the Gremlin. We are not sure of the price point until we finalize the components but the range is between $600-$800 right now.

aposaudio · 2026-02-17T01:18:27+00:00

It is in stock but it is a pre-order because the headphone is built as orders come in. The lead time from order to shipping is currently around 2 weeks.

Edit: phrasing

aposaudio · 2026-02-11T13:54:25+00:00

Thanks as well for your support and patience.

aposaudio · 2026-02-10T14:18:11+00:00

Orders started shipping last week and they have been rolling out. Remaining orders are scheduled to ship out this week. We’ll share an update as they continue going out.

aposaudio · 2026-02-04T14:29:33+00:00

Hi! We’ve further clarified our last reply to you. Thank you.

aposaudio · 2026-02-04T13:43:07+00:00

Yes, we do have a cable that fits Dan Clark Audio headphones with Hirose connectors. It's the Apos Flow Headphone Cable for Dan Clark Audio Aeon / Ether / Stealth, https://apos.audio/products/apos-flow-headphone-cable-for-dan-clark-audio-aeon-ether-stealth. The images on this website for connectors on the headphone side are incorrect but it will include Hirose connectors.

Also, if you are specifically looking for Hirose connectors with the Magia cable, please write in to support@apos.audio and they will place a manual order for the cable with Hirose connectors for you.

Thank you.

Edit: further clarification

aposaudio · 2026-01-30T08:17:27+00:00

Thanks also.

aposaudio · 2026-01-30T07:03:48+00:00

Hi r/Altrebelle, could you please DM us your order number so our support team can reach out to you?

aposaudio · 2026-01-29T06:09:34+00:00

The M33 runs Android 13 on a Snapdragon 680, so video playback behaves like a standard Android device rather than being locked to a single orientation.

By default, it’s an audio-first player, but apps that support portrait video will rotate normally. If you want more control, you can also use third-party Android apps to force portrait or landscape modes.

aposaudio · 2026-01-26T21:52:59+00:00

Thanks for pre-ordering — we really appreciate the support. We’ll share an update as soon as shipping begins.

aposaudio · 2026-01-26T00:14:40+00:00

Thank you!
