Hi ! Massdrop informed me my SAP2 was shipped yesterday. Should arrive before 8th May I hope. 42 € that’s a bargain I believe. BTY this is my first purchase on Massdrop, seems worth the wait as it is 69€ in Europe on Amazon.
Hi, I'm trying to understand. Is this SAP II the same as the SAP II Pro? I'm not sure if there is a difference, but I sometimes see it with a 'Pro', and sometimes, as with this case, without. Cheers.

I think it‘s the same. If you go to the SMSL website, they only list one "SAP II" head amp.

Mmm true, thanks
Good for HE-400i?

Would the Fulla 2 be good? or should I just get a standalone amp.

For $100, the Fulla 2 isn't bad. It's just not great compared to what a little more money will get you.

You'll probably be happier with an amp that uses external power rather than USB power. The HE400i is not exactly sensitive.

The O2 paired with a good, inexpensive DAC like the Topping D10 will run you a bit under $200 and be well matched to your cans. Or request the O2+SDAC drop again and hope it comes soon.
When are these getting delivered to California?
This looks interesting to me, but I can't pull the trigger without knowing its output impedance. Anyone got a clue?

Yeah, looks like a pain in the butt to find info on output impedance but I might have found it: http://reference-audio-analyzer.pro/en/report/amp/smsl-sap-II.php (orange line on first graph). So 10 ohm output impedance? I've merely heard about some of SMSL's amps having high output impedance, so that might be on the mark.

It uses a TPA6120A2 as the output buffer. This opamp requires a minimum output impedance of 10 ohms to prevent oscillation. The same chip is used in the Fiio E09K, Topping A30, etc.
I own the SAP-VI - mean little amp, though with a somewhat unaccomodating 10ohm output impedance. Any word on the output impedance on this one? I definitely like the minimalist look of this one with the blacked out text, centered headphone out, plus the 2 inputs are a boon.

just got in the drop, I have been waiting for this amp. Amp specs look better than my schiit fulla 2 that I use at office. So I will use the SMSL at office and bring the fulla home. I'm currently under utilizing the fulla - fulla features!.
BTY - I preamp the fulla by raising the volume of my pc to 90% and I can run most headphones up to 300 ohms. So the SMSL should not be a problem, so I hope. for $50, looks like a good deal.
Any word on if these are shipping today?

Got the message of it going out yesterday.
Hi,

I am new to Massdrop, was wondering if this item will ship to Australia, and if so, how much it would cost? Is there a way to find out? Thanks.

Sorry this reply is late, but since the drop is active again: Just click on 'Join Drop' which will open a checkout page where you can see options and shipping costs before committing to anything. Shipping to Australia is $3.75.

Don't forget the import tax, that may cost a lot.
Hi, I own a Fiio X3 First Gen and drive AKG K553 Pro (Thanks Massdrop). Do you think this amp will make a huge difference?
Also, does any one knows what is the shipment cost for Mexico?

Thanks
