The OPA2107SM were highly recommended for low noise floor, natural yet dynamic sound, but they've long been discontinued and hard to tell if the ones still floating around online are fakes or not.

Are the gold seal version known to have had fakes as well?

Any further insight to rolling? You guys have gone quiet!

Any joy with sparkos @bigbeans ?

N8ii/jewel is now fixed for me so naturally looking to add C9/A100 to see if they bring anything to the party.

@armstrj2 has N8ii+A100TB+PS100 Pro+Aroma Thunder

I don't know. These op amps have been out of production for so long, and there's no way to confirm any provenance. I am quite happy with the Bursons in the A100TB, I know it's noise but it doesn't bother me that much. Hoping that the pair of OPA1612s on the input would quieten it somewhat. Else you'd have to stack the risers like @bigbeans does with the Sparkos, if you want a blacker background.

Hey all, I published my review of the Aroma A100TB on the product page, but maybe it's better/more useful here. I hope you enjoy!

Which accessories comes with the A100TB?

 

[eskamobob1]

But I was looking for confirmation or the opposite, because it is a brand that very few have.

I have owned a 428 for a very long time and will confirm this. The power spec on the site is misleadingly low, but it's by no means a hugh power amp. For example, it doesn't run Diana fully, but will absalutely run d8kp at full tilt 0 issues. I love the amp quite a bit and it's actualy my favorite amp ~1k used regardless of formfactor (prefer it to GSX-mini, v281, phonitor, etc). I haven't heard the a100tb or any a2p stuff, but I've owned basicaly every other portable amp on the market and the mk428 is realy in a legue of its own (in terms of technical ability) from any other portable I've heard

Man, I just got my Aroma Audio A100 combined with the Power Station and with OPA627SM and SS3602 OP Amps and I am really blown away by how good it sounds. I have a few other op amps but for the moment I just want to listen to music. Later I will compare it with my Romi BX2 plus amp and with Cayin C9 amp but as of this minute I like this quite a bit. I wasn't expecting such a great sound from this stack but I am glad I bought it

 

[immortalsoul]

Not to mention that it is the same size with the Cayin N6ii that I am using to feed the music

I am wondering why this stack is not getting more attention because quite frankly it sounds unbelievable

Stack=.....stack.

Any idea what the wattage or milliamp hours are?

Sorry, no idea. I bought the amp used from a fellow head-fi-er. I am new to this changing the op amps but the guy said the op amps are an upgrade from the stock and I believe him because it sounds incredible

 

[weexisttocease]

I'm thinking in getting the A100TB. There's any interconnect cable you would recommend?

This is the one I use. It's a 4 wire cardas clear that I got @doctorjuggles to make for me. Sounds excellent.

Amp is 800mw max output

 

[immortalsoul]

What op amps do you guys have and use? I have the OPA627SM, the OPA637SM , SS3602 and Burson V6 classic. I am smitten with the one that I have right now but definitely I will try the rest to see which one I like the best but I don't know if it can get better than the ones that are on it right now
