@ditusa The two articles you cited cleared up some significant points of confusion I have had about balanced connections. Turns out I’ve had it all wrong about the signal ground all these years. Thank you for sharing.
recommendations for buying used balanced integrated or power amp 2k range?
any suggestions?
would be used to drive a variety of tower speakers with sensitivity above 89db
source would be rotated for the time being between between bluesound node and Lumin d2
the amps that come up regularly in my area for sale used are Yamaha s2100/2200 and Ayre AX7e
