I can report that the SQ on the latest 0.9y-5 on Win7 64 into my Berkeley Alpha DAC is a nice improvement over 0.9y-4.  As to the engines I find a slight preference for engine 4.  Engine 3 to my ears is a tad more smooth, but less live sounding.

There's Nothing So Dated As Yesterdays Future

If latency does nothing but changing SQ
OK,

When you want a TRUE compare of for eg. upsampling vs no upsampling you should adjust latency accordingly.
Why ?

When you double the samplerate you half the latency as your using the buffer up twice as fast

So should there be bigger buffers when using QAP or oct-AP,
to keep smooth sound ??
 Happy

So, QAP can only be better then DAP (@ 2048) if Latency goes above 2048 to lets say 4096
or WOW how low can we go right now, without SQ changes.
if TRUE compare upsampling: DAP set @1024 vs QAP set @2048
Right ?

I can imagine this is not a nice thing for the volume control and overall speed (it will take longer again)

Yes, true. But so many more things are involved that I wouldn't bother about it. Theoretically true though.

The volume change taking longer will hardly be noticeable because it takes "relatively way long" already. Notice that if 48 samples incurs for 1ms, 2048 will be 42ms. You won't notice that (you will when playing a keyboard though).
