Phono stage hiss - Measurements

[Greg]

A quick follow up on this thread.  I received an email from Mathieu Pernot today.  Apparently he has analysed the recording from my phono stage, but he is, to quote; "still waiting for similar recordings from the various gentlemen suffering from this issue." 

To further quote; "I'd like to compile results across as many users as possible."

I know that @thumb5 (Ian) has sent in his recording.  Is anyone else able to do this?  It would be great if we could get some more examples sent of to Mathieu.

I must confess, I have not yet sent a hiss recording to Mathieu and really should get it done, particularly as I was the very outspoken guest at the Oxford Audio Consultants day with Mathieu, and I was the one who raised the issue with him. Unfortunately, I don’t know how to make this hiss recording other than it requires the use of the USB socket as an output and a laptop. I don’t own a laptop. I have a friend (he has no time for instruction of others) who I can confirm will record it when he’s next around. Of course, if anyone in the meantime can give me some instruction on how to do it (wife has a laptop I might be able to borrow and I have a Dropbox account) I’ll certainly get on with it. Any instructions will need to facilitate my digital Luddite ignorance, but, if laid out simply, I am able to follow and action on.

Of course, my other reason for being slow here is my own solution of using a Longdog Audio MCJ3 Hybrid Valve Phonostage into my D250 at line level which produces for me the very best sound presentation from vinyl. Unfortunately, Matieu’s view on this is what I have done is a ‘ridiculous’ solution. I don’t doubt his opinion, so probably all the more reason for me to get that recording sent off
