yep, thats what i have been trying to say but I guess i coudn't describe it well...
I'm glad to hear i'm not just imagining it...

probably true with the USB. I first realized it when I had it hooked on my ipod>LOD when I was playing around with the gain switch.

x2 Is this the method for biasing OpAmps to Class A? I'm a little confused because on my PPAv2 this is achieved with trimmers. Can you comment Ron, I wouldn't want to be missing out on anything

To appreciate the subtle nuances revealed by using Class A bias, it does, of course, require the use of high-quality upstream components and good phones. High bitrate or lossless recordings are also a must.
To date, I am using output bypassed AD744s running Class A, AD743 Class A, and OPA27 Class A for use as a P3 buffer.
And the rolling continues!!!!!!
WOW
class A in the D10
(how does the AD743 classA sound in comparison to your topkit?)
once more
you are pushing the envelope,
attacking my wallet, Ron

Thanks for the reply!
Never thought it that way. I always think that headfiers are one of the most generous people in the world. Cheers.
I prefer optical to USB by far when driving D10 or D10->lisa from my Mac-> RME Fireface 400, but I prefer Coax over both of them. (cryo 7N UP-OCC silver double shielded (5N silver foil and SPC braid) with silver bullets.
just use a plain USB cable (remedying that shortly after some more research) but I just find that both optical and coax have considerably more air and dynamism, with added resolution. USB to me sounds like its trying too hard and is a little congested IMO, while spdif produces effortless detail.
Do you get Coax digital from your Mac? Have I missed something?
I always prefered digital coax to digital optical, too.
I would describe it in the way that with digital out from the Mac to the iBasso d10 the sound becomes more detailed (so far natural), while over USB it is "harder", some micro resolution missing.
(On the iBasso D3 this effect is compensated by a smoother amp part.)
Connected to an USB Monica (which has a reclocking unit - Does any portable have such a feature?) this effect is less obvious .... I can not recognize it.
edu, I have had information from iBasso that they "are using another brand's jack now".
That is all they said in relation to my request that they use better quality components in my similarly afflicted D10. Let's hope that deals with the issue.

when I put on high gain, I don't get much difference in sound volume (overall except for the mids) but I am hearing the mids becoming more forward and louder, where the sound is quite nice but without much depth.
In some opamp configurations, I don't notice ANY difference when going hi gain from low, in terms of SQ, and sometimes there is no difference in volume either.

Yes, this is the method for modifying a 744 or 5534 for Class A operation.
One must remove the #6 pin, connect the #5 pin to the #6 solder pad, then use a 2.2k resistor to bridge #6 to #7 pin.
There isn't much room on an adapter for using 1/4 or 1/8 watt resistors, so I use SMD resistors. They are so tiny that they don't interfere with mounting 2 modules onto a 2>1 adapter.
I haven't yet found a good (easy) way to modify a dual-channel opamp to Class A operation. Maybe down the road when I get more hacking time.

The D10 gain switch actually only results in a 3db difference in gain. This is about the lowest volume change one can detect by listening.
