I'd love to say that I would prefer not to hear all this flattering stuff, but that would not be true. However, ahem, all those genuinely committed should merely send money to my Rosanna address, listed on my website.

I promise I shall spend it all on high living, none of this R&D stuff, much too difficult, and I know it all anyway......

My Toyota engine has AGAIN blown its head gasket, second time in six months. This time, the motor is trash, it will have to be replaced. I'm mulling over whether I should be a complete lunatic and put in a Lexus V8 - I know it fits just fine - but it's a lot of work.

Maybe just the 2JZ, a very good in line six. Hmmm, what to do......
Gaetan, please go ahead and post! There is no such thing as bad publicity, and who knows, in a year I could be utterly irrelevant!
Could I posit a pet belief about amp design? I think it is merely detective work, this is the inspiration, and the engineering comes after the vision. And I think the engineering is pretty straightforward; it's obscured with high falutin' maths over and over on some forums by highly educated people, but all this debate doesn't seem to produce a better amp, although some are good, like Edmond Stuart and Syn08's latest Error Correction amp, which I suspect is very good indeed. You can design a good amp with a good understanding of Ohms and Kirschoff's laws, the reactance formulae, a good CRO and meter, and a lot of careful iteration and listening.
When you read NP's articles on amp design, it is clear he sees characteristics and phenomena first, not maths. His explanations are fairly simple, he cuts straight to the chase, he makes subjective comments from time to time about the sound, and he never gets carried away with how clever he is. The answer lies in the topology, not the math, and they are very different, and he really has it sorted out in his mind. I know this because I've followed his work closely for years, now I've met him, and I see someone who goes straight to the nub of the problem without being sidetracked by peripheral, highly academic issues which are more about showing off than producing better amps.
I honestly think that amps could improve a long way yet. There's much more sonic quality to be extracted, and this is really great because I'm only 56 and I'll see a good deal of it before I get to know John Linsley Hood in the sky......
Some time ago when switching amps came on the scene I bought a Hypex UCD180 and gave it a good listen. I concluded it would be a long time before they rose to the standard of a Class A, conventional design; meanwhile, the Class AB designs are also getting better, and in my opinion the quality of the switching amps, while improving, is not supplanting the analog designs, at least for high end. I like the efficiency of these amps, they are an engineering masterpiece, but they generally don't do music very well as they don't engage with the ear.
Lastly, in this gratuitous audio gossip column, the main threat to high end audio has been, and remains, the very low standards we've all become accustomed to with the digital age. The main culprits are iPods and MP3. After a NYC buying spree (thank you Paul!) my two daughters are now each proud owners of an iPod Nano and one remarked to me, 'Dad, I love it, it's changed my life!' - I was deeply shocked to hear this

MP3 and crappy sound cards and switching amps in auto radios and cheap handset players have really dumbed down audio; we've all forgotten how good it can sound. I will never forget the sound of our neighbour Fred Bryant's Williamson amp which I first heard in 1958, it was wonderful. Fred was a wonderful man, a farmer intellectual who loved classical music, but he died young of leukaemia. Then my Pa had built a very nice Mullard EL84 PP player for my Mom, and I spent a lot of time listening to it over the years. That was when an OC44N germanium transistor cost an arm and a leg, and a kidney, eye and pancreas thrown in....
One thing RMAF showed me conclusively is that when listening to a system, 95% of people think the sound quality comes from the speaker, not the amp. The truth is, in my view, that about 60% comes from the amp, with the source and speaker making up the difference. The distortions of an amp can sound truly horrible, no question. I've always been able to pick a great amp with even a lousy, el cheapo speaker. It really stands out.
Pardon my rave, it's about to pour with rain and I'm feeling chirpy.......

Cheers,
Hugh
