SMSL D1 - ROHM DAC for everyone

I changed all opamps to opa1612 and sound has been improved to next level.

I guess you could say it has been improved immeasurably?

 
Well, then, I finally ordered a SMSL SU-1, let's hope for the best...
From what I’ve read, you’ve made a good choice. My SMSL RAW MDA-1 has been a fine performer for me.

Only through your perceptive biases.

Any change to the actual sound reaching your ears will be so small as to be non-detectable by them. Unless you've actually managed to make the circuit unstable.
 
Oh hell no this guy did not just claim he has special hearing abilities because of his age. Listen, junior, I might not be able to hear over 11kHz, but try putting a 10kHz low pass filter on your music and unless it's an album of Mariah Carey breaking wine glasses with a dog whistle backup orchestra you won't notice a difference. Now go get your shinebox.
 
Looks like the D1 is unavailable to purchase on aliexpress again.

It is simply unavailable for certain locations—unfortunately, a very common problem on AliExpress.
Es ist beispielsweise in den USA erhältlich.

Looks like its US only currently. Quite bummer as i wanted to buy 2 more during the summer sale for experimenting with DSPi. Yeah i can buy it from local stores but the cheapest one is 115€

It would be much easier if we knew which country you are in; then we might be able to offer you many more tips.

Why don't you order from HiFi-Express? They have 8 units in stock, and the price is reasonable. Their summer clearance sale starts tomorrow—it might be even cheaper then—but you'll have to act fast.

What about Amazon? (Again, the location issue comes up for anyone trying to help you.)

Otherwise, why not ask the official store directly whether—and when—shipping to your country will be possible again? Sometimes they simply forget to update their online inventory.

I prefer to use ali since i use it for 12 years now.

Not viable for me.

The SU-2 is looking a better deal after more searching as it have balanced out and mains powered.

For one thing, you would be buying from the same retailer, and paying via PayPal is more secure than using AliExpress (though this does not apply when using PayPal *through* AliExpress, as PayPal will simply refer you back to AliExpress in the event of any issues).

The SU-2 is also not a bad choice, but keep in mind that you would still need a DDC for USB connectivity.
