Leaving Class A or "Why our meters don't go to zero".
Good article by Nelson Pass of Pass Labs talking about class A, AB and effects of bias. Nice easy reading. http://passlabs.com/pdf/articles/leaving_class_a.pdf

A very interesting article,. Serge. After that I found several more reviews which also rave about Pass Labs amps. Of course, how often do you ever read a reviewer really pan anything? They are out there to grease the wheels of the audio business. I want to hear some PassLabs amps as well as Lamms! Nelson Pass is able to design more power into a Class A design. I wonder if they sound as good as the Lamms? There is some interesting equipment out there... Ted.

Serge,
Speaking of Lamm, have I asked you if you have ever heard the Lamm M2.2?

You can use this calculator to approximate what kind of SPLs you can get without leaving class A. I get 105dB with my 88dB speakers right now before the amp would ever slip into class A/B. Most of my listening is 85dB with peaks around 95dB. http://myhometheater.homestead.com/splcalculator.html |

Thanks PHC1 for the calculator. I am at 115.9db.

Most reviewers don't "pan" products from legitimate mfrs., because none of them are making junk these days. So much of it is about system synergy, set up, the listening room and software quality, there are too many variables. Being overly negative or gushy on a regular basis doesn't help the reader. As much as you would like to think we are all "greasing the palms of the audio industry," to not describe a product as accurately as possible doesn't help you, me or the mfr. The Lamm amps are a great example. I've always found the Lamm stuff to be way too dark for my taste, yet when I've heard them with Wilson Sophias or Sashas, the sound has always been fantastic. It's never an easy conclusion to draw. Ultimately the best hifi review will lead you to a product demo so you can draw your own conclusion in your own system. Nothing more. |
