You don't even need to read past the OP's opening statements to see what coming.
I focused listening to three instruments in SRV's tune.Tone/dynamics of the guitar, the crack of the drumstick against the snare rim and bass. Umm... nothing. Maybe the vocals were noticeable, but the song is cut before SRV starts singing.
If there is any change in presentation, I still should be able to hear it the Ipad speaker. Whetever difference there is, very subtle.
I put my on my guitar player ears for the comparison.
Heard no difference in the depth of reverb or decay in the crack of the drumstick, guitar and bass sound the same.
I then played my own period LP copy on my table. Thanks to the Ipad, my under 20k retail system sounds superior to that obvious nice/pricey rig. My system does have ridiculous cabling and PS Audio regen.
Let the OP hear what he hears and report his findings and everyone else can buy SR products.
