Found it. They’ve made a new one. Just search “DDHifi storage bag” on Amazon and you will find it.

Carful with this as they make several cases that look similar with different configuration. The DD2021 is almost a perfect fit for the C9 but no room for a DAP. The 2020 is larger but I don't have one to try if it can take c9 and a dap.

Posting some impressions of SP2000 and C9. Most of them have been mentioned by fellow C9 users, but just want to add one more data point.
  • SP2000 can benefit from adding a C9 to the chain, even in terms of driving IEMs. Essentially all the aspects of the music improve: The bass is higher, mids with better textures, and trebles further extend. Soundstage and overall clarity improve. Put it simply, with SP2000 alone, IEM still listens like an IEM. With C9, the boundary between IEM and full-size headphones becomes blurry to me.
  • SP2000 is a super convenient source to pair with C9 if you are a Roon user. Tidal/Spotify works very well without saying.
  • N6ii + A02 and SP2000 as the source sound differently. N6ii +A02 seems to have better clarity, and the two offer different sound signatures. Will need more time to be able to talk about the exact differences.
Ah! Now you see what I said about 50 pages back is true, that the SP2000 loses clarity in line out mode. This was clear to see with the N8 comparison and also A02.

I assume the same would be true of the Max? Keep it low gain just to be safe.
I have used the DX220 Max - 4.4mm Line Out on High Gain (I am assuming the High Gain setting impacts the Line Out and the Phone Out, but not sure on this)...and also had the C9 set to High Gain...with no issues. I did have the DAC volume on the DX220 Max set to 135 (of 150), so 90% of the DAC volume.

Guys, anyone has the C9 and the Romi BX-2 Plus that could compare their Class A amps? Other than the difference in power, I haven’t read any comparisons.

The Korg Tubes are a definite plus for the C9, but it’s something to think about when comparing a $700 USD vs a $2000 USD portable amps. :)

I have the BX2 Plus and the C9 on pre-order. Will gladly provide a comparison when it comes.

I covered it in my C9 review, scroll down to comparison section, I have brief notes in there.
