Ian>> Beyer DT531 - I believe they are 250 ohms but not sure.
Yes they are.
>> Eminent Audio Vitale
They have a 4K ohm output impedance.
I am surprised that they drive them ay all!!!
So you will definitely need a headphone amp.
Sorry ...>> Can a simple swap of a volume pot be implemented to
>> any valve pre amp without to much effect on the cuircuit?Volume pot only determines the load given to the source.
It will not increase gain at all ...
Unless you get a transformer volume control which
have the option of 3 & 6dB gain - on some anyways.
Since you're in UK - S&B TX-102 is the best.Other than that I am of no use to you.
I am not a headphone user so I'm out of my element.DanL
