Hi Gregm I have the orginal yba2 not the 2a so I presume that there is a BIG difference in sound in the 1a versus what I have now and yes I can upgrade for about 2500 and my pre is a Linn Karin about 93yr.Haven't listened to anything else as yet,I live in a very remote area makes things diffucult to audition..My main concern is muscality then detail resolution and then sound staging .I listen to classial folk and voice..thanks for replying ken
