being a Vinyl Enthusiast I prefer older amps with well sounding phono Inputs. Currently I own and enjoy an Arcam Delta 60 with 2x55W form the late 1980ies.
My Sennheiser HD580 sounds very well out of the Arcam´s phones jack. But the AKG K500 sounds thin and bloodless. I know, like many AKG types the K500 is difficult to drive. But in the past it sounded much better connected to a Yamaha C60 preamplifier.
In the Arcam owners Manual there is no Information about the Output impedance of the headphones jack. Does anyone know about it? If it's high, I would try to replace some resistors by lower ohm rated ones, hoping it would increase the phones output power and make it more suitable for low-z headphones.
Is there a way to measure this value?
Thank you in advance for your help!
