I sure can elaborate from 10 years of discussing this exact topic with new high end gear buyers at Audiogon,much of the new gear buying community is afflicted by the belief that the less in the signal path is better ,and presents a more accurate sound ,the way the musician intended us to hear ,notice the lack of tone controls and a loudness contour circuit on all high end brands ,except McIntosh ,audiophiles who won't buy a preamp due to it having tone controls in the signal path and they will not buy amplifiers with Autoformers,if you don't believe what I'm saying simply log in to Agon & do a search of " Autoformers " ,while most are influenced by the unnecessary circutry in the signal path others have real world issues where autoformer amps aren't a good match for their Electrostatic speakers or other low ohm speaker designs .
