    But maybe not as much to answer for as the dickhead who collected up most of the known info on Blumlein, interviewed his widow and colleagues, made pleas in the electronics press for people to send him anything they had on Blumlein... and then did now't about it in spite of public shaming over the affair for 20+ years. He died without publishing anything. Thankfully someone else then managed to get hold of all his notes etc and wrote the book the world of electronics had been waiting for

    Are audiophile mains leads designed? If anything, they are carefully chosen cables available "off the drum" and fitted with good quality connectors.

    I'm sure if there had been hitherto unknown properties to a mains cable then one of the luminaries on the list (especially Blumlein!) would have found it.... not to mention all the other geniuses working for the likes of Hewlett Packard, Marconi, EMI, NASA, Philips, Sony, Fermi Lab, M.I.T etc Maybe audiophiles discovered gravity waves years ago but were too busy cleaning "Jazz at the pawnshop" to tell anyone?

    But we're getting off topic now

    I still have a couple of his hybrid jfet/valve line stages and his re-working of Hafler's Dynaco ST 70. I built it more than 20 years ago from his article in one of the first issues of Glass Audio.



    One of these days I'll bring it to NEBO.

    Hi Gordon. I'm sure plenty of us will take you up on that one!

    As you touch on, it is impossible to make a real list of great amp designers because the majority were/are back room technical people who never saw the limelight... But, a few do deserve mention and I will also mention that a few you named definitely don't! Antony Michealson is no amp designer for a start and Julian Vereker can hardly be called an amp designer for copying an application note.... good business men yes.

    Here's some of the real greats in no particular order:

    Alan Blumlein
    James Bongiorno
    Peter Walker
    Mike Albinson
    Aubrey Sandman
    Susumu Tanaka
    Tim de Paravicini
    Doug Self
    Arthur Bailey
    Peter Baxandall
    David Hafler
    Nelson Pass
    John Curl
    Joe Curcio
    John Linsley Hood
    Erno Borbely
    Malcolm Hawksford

    Apologies to the ones I've inadvertently omitted and some big names deliberately not there as they were primarily business men not designers.
    No mention (yet) of Colin Wonfor nor Bob (Robert) Stuart? Had the original interview taken place when I became reconnected with CW I'd have certainly included him in the designer heroes-I-have-met.
    Well, hello.

    I was going to mention Bob Stuart, but didn't as I thought you had already included him in you interview. The same for Stan Curtis.

    I think Siegfried Linkwitz should perhaps be on your list, Jez.

    I wonder how many speakers use his crossovers (developed with Russ Riley) and his work on acoustic theory is up there with the best.

    Indeed, which is precisely what I've done with my 'French specials'!
