Hi Guys ..
A few things to point out here please as I've actually owned these models ..
The Denon DVD-3930 was the direct successor and somewhat short lived model to the 3910 !... I had both models and the 3930 Denon definitely stepped up the internal hardware and build quality and it had 2 independent PSU the 3910 did not ..also to note the 3930 had a lot of the tech imported down from it's bigger brother A1XV just half the price take the top of both models and your quite clearly see the big differences between the two.
Moving on again I own both models Denon DVD-A1 in my humble opinion still edges the A1XV especially when it comes down to the Channel Pure Direct mode playback the A1XV is outstanding but the A1 has the famous Burr-Brown 1704 DAC's...in Dual-mono R2R configuration mode for direct Stereo playback their is also a lot more attention to details with the A1 than the A1XV model ..again the A1XV is still an outstanding machine and it was a later model and had far more digital circuitry implemented in comparison to the A1..So Denon was starting to scale some things back budget wise by the time the A1XV came out .
Lastly the DVD-A11 was the direct successor to the A1 ...their is absolutely no comparison whatsoever from the 3910 and 3910 .
The A1 in particular was created and produced as an absolute Denon's Reference model !!! The 3910 and 3930 were flagship grade not reference.
The A11 is also another outstanding model but by this time compared to it's predecessor the A1 Denon had started to make some sacrifices/trade-offs for budget again due to advances one of being SACD more digital circuitry and licensing agreements so side by side again attention to detail internal and external their are significant differences!!!
However both A1 and A11 were designed as Denon Reference Grade models .
So it went Flagship Grade approx £1200-£1500
2800
2900
3910
3930
Reference Grade £2.5k+
A1
A11
A1XV
A1UD
Personally despite the A1XV being Denons last stand and Denons Golden period and a super nice model design and electronics...I still personally believe

the "A1" looking back was Denons "true" finest ever model produced and most expensive and finest ever sounding sonic wise that's just my own view and opinion.
