7.49 set's mqnplay to realtime priority, improves another unmeasurable aspect of the sq

the exe is back up to 140kb, so the next thing is to trim that down to 2kb and that'll be that.
7.49 1644 Normal is stunning. Def my best yet and my new reference.
Everything about it is a step up from 7.41 V93PA which was itself very good.
A proverbial veil lifted. Dynamic and detailed but also no hint of harshness.

One thing I noticed in Task Manager which I haven't seen before was that MQnPlay.exe when a single track was played took 2GB of RAM and CPU % a steady 30.5%. Both readings somewhat surprised and concerned me.

Is that to be expected, Gordon?
Same for me gone from 0-1%cpu to circa 26% on 7.49, 7.48 has disappeared from the google drive.
Will give a longer listen but initial impressions is it is a little soft sounding but very pleasant.

Gone back to the last PAV93 and 7.41normal. Can't test the subsequent PAless versions

9% on haswell i5

anyway, a bit of investigation found there was a major flaw in the loop, now fixed in 5.75

cpu down to 0.1 % and storage as per track length.

if you thought 7.49 was good wait until you hear 7.55 etc

Yes 7.55 working fine here and down to 0%. Maybe reporting too quickly but seems very dynamic, excellent. Veil lifted here now.Using first track on Agartha tonight for testing a bit of squeaking Miles always useful for treble ache.

Good news. What is strange, is that a render loop with such a major flaw could sound so good!

7.52 24/96 and 7.50 16/44 work both with my Teac Dac and my M2Tech Dac (Xmos). Beautiful sound.

Unfortunately, 7.55 is not working:
-Teac Dac: no sound at all
-M2Tech Dac (Xmos): crackles.

Tested it with two computers, same result. I use MQNLoad.

I think it has something to do with MQNLoad. When I first choose 7.49 and after that I choose 7.55 then it's working. Not tried hirez.
