Thank you for your message. We 100% make sure that the SU-9 you received is the one with the latest firmware. You may also find that most previous firmware versions were based on S.M.S.L DAC+ numbers, and SMSL also updated a brand-new serial number recenly with the new firmware to make it easy for us to distinguish it from the previous version, and we don't need to verify when the SU-9 was purchased. Please rest assured.
Dear Shenzhenaudio [hereafter SZA], thanks again for recent and kind reply.
This might be my last question for updated-or-not SU-9 to rest assured as you said.
StevYu and I bought SU-9 from SZA.com almost same time, and asked same question here to SZA.
- Ask SZA to confirm shipping 3rd harmonic patched one before purchase : Jul 12 vs Jul 12
- Order date : Jul 12 vs Jul 13
- Order No : #SZAW13757 vs #SZAW13790
- Serial No : 3200010200428 vs 3200010200420
1) He (StevYu) asked first how to find out updated-one (Jul 19), and SZA answered that check side sticker S/N (Jul 20).
2) He said that his S/N is 32000102004**(Jul 20), and SZA replied that "THAT'S WEIRD. PLS DM to SZA" (Jul 20)
Anyone can know that this SZA's comment (weired..) clearly states that SU-9 with S/N 32000102004** has not been updated.
3) I (bauerctu) asked almost same question as StevYu's Jul 20 post (Jul 23).
4) SZA now answered that with or without side sticker, bauer's SU-9 is latest firmware SU-9 (Jul 24)
You know, 3rd harmonic patched update version and previous firmware version has same firmware Number. It hasn't been changed. In this situation, buyers only confirm updated version by side sticker with S/N DAC6*****. SZA already posted that updated one has side sticker (Jul 20), and if there is no side sticker at recently purchased SU-9, that is wired and should directly contact to SZA (Jul 20).
And four days later, SZA suddenly and totally changed, answering that with or without side sticker, all recently shipped from SZA (StevYu's and Bauerctu's) SU-9 has latest firmware.
Honestly, I can't believe SZA's Jul 24 answer. "It's weired (Jul 20)" vs "rest assured (Jul 23)". Since SZA is a large seller, not a small one, I think SZA should exchange my and StevYu's products to one with side sticker DAC6**** S/N.
Because both of them inquired about the update-or-not before purchasing, and received SZA's confirmation that SZA will ship 3rd harmonic issue patched SU-9. Exchanging would be a one and only reasonable solution to this situation.
PS. dear StevYu, did SZA already exchange your SU-9? let me know, thanks
