Okay, how do you guys play music ordinarily then?

I used to play music with mqn by just pressing a hot key command. You use older mqn versions for casual listening?

Normal listening is done here using 4.25/9.12 started via batch after Ctrl-C from explorer window.

The tri-split versions are only used for testing and occasionally a single track that is just over 50MB full size.

As an alternative you might use Taggarts tool MQnLoad with the old versions as well. It gives you additional possibilities like easily changing MQn versions or playing flac with MQn. It has been introduced earlier in this thread.

Take care

uploaded v25 uses different low level instructions, not sure which I prefer, this one seems to have more detail, less thumping bass.

v26 back to previous instructions, bit better all round for detail, but still has good bass. Right, must get onto the device name

v27 alignment fix after all these changes, if you only listen to one this is the one to try.

whats the buffer/period size these days?

briefly tried v24 earlier seems a good improvement on the last ks i tested

Nigel can you fire over the folders when you get a chance. Not sure if it is my room or MQn but the 63's are a completely different beast tonight.
Wonder was Pearse using Ultrasteam even at Scalford? Maybe hibernate might have helped but I think judging by comments from lots of other people bass boom issues abounded in Scalford.

Gordon did you make it to the show??

So JPlay dac link is just using the device driver interrupt to time the swapping of buffers.

With MQn there is no swapping of buffers because there is no copying of data or streaming and it has always used the driver interrupt to time the next buffer.

I tried JPlay 6, but found the 0.5 ms system timer setting to be too digital (why not make this configurable ?), so it is my impression that they equate increased resolution with increased digital noise which is the opposite direction MQn took. If you decrease the buffers then you are just increasing the digital noise because the same instructions are being run more often than with larger buffers, there is no reason for lower latencies, it's not a musical instrument that needs to play sound as soon as a key is pressed.

Too many compromises with JPlay.

dont think jplay is a good benchmarker for sq maybe more for usability
but can we not lower the latency even just to 5-10 ms just to see what the guys here think of it
