A thread should be started for the Pico. It would be easier to know what is going on with it and what the different configurations are as it would be a dedicated thread to the Pico.

I ordered my D1 and should get in in 10 days or so. I plan on burning it in for 400 hours and meeting with HiFlight to compare my stock unit with his modded one. Then based on what I hear I will decide on rolling op-amps or not.
I already asked Ron to build for me the various configurations for which I will gladly pay even if I do not use them. However, having exchanged emails with Ron as well as listened to his rig I am pretty sure he is unto somthing.
Meanwhile, back at my D1, I have just past the 150-hour mark on the burn-in (stock, with the DAC running constantly, fed by lossless files from my MacBook's optical out), and can report that BIG changes are afoot.
Suddenly, the iBasso has dropped a pair of enormous cajones in the bass department; convincing, well-defined depth of genuine authority, without any apparent traces of looseness or flab.
Soundstage has broadened quite noticeably, while attack and decay have become increasingly organic. And I'm just beginning to hear signs of the top-end sparkle I've been enjoying with my CanAmp (which I have not yet compared the iBasso to).
Of course, I am excited to see reports that the D1 continues to refine its presentation well past 300 hours and looking forward to whatever other surprises lay in store.
So perhaps tomorrow will be a good time to roll in a couple of different op-amps to see what they do. But I'll switch back to stock for at least the remainder of the burn-in period, however long that may end up being.
I've been listening exclusively through my 40 ohm Ultrasone PROline 2500s. Can't wait to try my Edition 9s, but first I need to source a longer 6.3mm to 3.5mm plug adapter, as I don't want to stress the D1's headphone jack with the stubby adapter that Ultrasone supplies.
I just got some Proline 750's and they sound very nice with the D1. I am surprised they sound as good as they do fresh out of the box. The bass has very good definition with good hall decay.
Question to D1 owners:
Would you have bought the D1 at the current price if it was a standalone DAC ? With the same specs just without the amp. If not, what price would you pay for it as a standalone DAC?

Probably, a DAC was all I was looking for. The amp is a bonus, and if opamp rolling delivers something stellar I will be quite happy.
On a lot of DIY amps it is possible to adjust the gain by changing one (or several) resistor values. Has anyone tried dropping the gain on the D1? Volume at 10pm is pretty loud with my HP and I'd like a little more latitude with the volume control.

Yes that was exatly why I bought it, to get better sound from my Sony player with my Xin Reference. If however it turns out that the D1 rolled will equal or better the Reference then double bonus and one box less to carry.

No, I wanted an amp and DAC in one, but I woulda paid over $300 for a D1 if it came from the factory with the OPA2111/AD8397 setup with the current reviews of that setup...
Followed your instructions, place the new opamp with the shiny dot on the bottom left (identical orientation compared to your picture), but I did not find the marker on the socket to confirm that. here's a picture of the new setup, does that look good?
Also the 8066 is sitting way lower than the stock opamp which is mounted on plastic holders. Is that a problem according to you?

From my 4th post in this thread:

Naturally, I'm hoping for the best, and if the amplifier section turns out to be fabulous, it will be icing on the cake!
So the D1 has already far exceeded my best expectations as an amplifier. My Go-Vibe has been demoted to back-up status, and I'm looking forward to seeing just how much further the iBasso will evolve.

Cheers,
This isn't John, but I can confirm that your installation looks correct. The square dot on the adapter is always the #1 pin and you have it oriented correctly in the socket. If anything, the shorter distance of the pins to the socket are advantageous, as it can lower resistance and stray capacitance slightly.
