Project X part III-making a noise!

That took time! I was just combining the contents of two older micro sd cards to a newer Samsung 64gb one as the originals were smaller in capacity than those you can get today and as it was works by the same artists were split between them which made no real sense anymore.
Cards of  that capacity now can be had for around GBP £18  easily so I think in so far as anything in lossless full cd quality that'll be my minimum size.
Meanwhile on Project X, we've wired it up to the speakers it'll be used on in my rest room for when I'm feeling rough which is fairly smallish.
I've had these for a while being the bigger and more general purpose base model to my regular Wharfedale Diamond IV, which are a ported mini monitor come bookshelf speaker designed more for absolute accuracy than efficiency .
The Delta 30's go a bit lower at the bass end and are 2db more efficient which is as well as although the SMSL SA 36 Pro is quoted as delivering 20 watts per channel, when you look at the integrated circuit manufacturers website, that figure is quoted at 10% thd+n distortion where most regular amplifiers quote the output relative to 0.1% or less and so in reality it's more like 8 watts.
In practical terms, in a smallish room with these speakers you can fill the room with relatively loud music sounding clean with the volume control no further forward than '11 o' clock'  leaving some capacity for sudden peaks.
With the other speakers you'd need an output rated more like 20 or more watts at 0.1 thd+n distortion or less to achieve a similar volume in the same sized room.
