That is not what happened when I clicked on it.
Is it possible to power the Tone2 completely by the USB 5Vbus?
Thx
Matt
Yep.
We will release the technical specs also the schematic of Tone2 on the launch date.
The USB Vbus powering is very nice 
I appreciate also that the Tone2 seems to have neither MQA support nor a HP amp.
Hoping very much that it sounds even more musical than the Tone1.

Yep, Tone2 is a upgrade for Tone1 with Balanced RCA support 
And also similar performance with his brother the Tone2 Pro.
Good day!

Thank you.
Thank you! Have you measured the 2000 MHz for the A35 cores after all that Amlogic cheating or are you trusting in some sysfs number?
Since you’re using the fake 1.5 GHz clockspeed in your comparison this is a serious question. S905X on your VIM 1 is clocked with ~1415 MHz and not 1512 MHz as the cpufreq driver claims.
‘Linux 5.4’ is really bad since it is an indication for S4 family (S805X2 / S905Y4) suffering from the same problem as T7 (A311D2 on your VIM4): no mainline Linux support in sight anytime soon or at all.
Edit: just realized that AV1 decoding is also missing in your comparison PDF. I thought all the time that at least this would justify calling VIM1S an upgrade over VIM1

Nope, it’s more crippled since only 2 PCIe Gen2 lanes and both are pinmuxed.

Your script is saying the VIM1S/S905Y4 does support the frequency up to 2.0GHz.

Thank you! So I guess VIM1S gets a ~434300 AES score when benchmarking with openssl speed -elapsed -evp aes-256-cbc, correct?
But sbc-bench results will fly in soon anyway…
@tkaiser You can expect data and performance to be released gradually 
Well, quad-core A35 at 2.0 GHz already tells almost the full picture. The unknowns are ARMv8 Crypto Extensions present or not and memory performance which I would expect to be rather poor so hoping for a surprise
And for those interested in media capabilities lacking AV1 decoding according to your comparison might be a bummer…

Actually, VIM1S/S905Y4 supports the AV1 hardware decoding:
We will update the specs & comparisons table soon, and thanks for point out thus information that the audience might interest.
BTW, we will also release the S905Y4 datasheet to Khadas Download soon.

The S905Y4 has been available for a long time and datasheet is freel available on internet. Yes it has Crypto!.

Yes it was, like many other free hosting sites it offer slow download free or pay for high speed subscription. As stated file is small, lower download speed was no issue. You just knee jerk assumed with no reading comprehension. Khadas had/ has the link and can/could check for themseleves or should i post a screenshot which you no doubt will scream different ! You decide, be dim or own up.

Do you mean technical upgrade or also sounding superior to Tone1?
FYI, I do not use the balanced RCA.
Is there a SQ uplift also with unbalanced RCA?
Thx
Matt
I think so, but you can still refer more feedbacks from the reviewers.
The balanced RCA is compatible with the standard unbalanced RCA.
