Was is Nelson Pass who designed the Soundstream car
amplifiers when the company first formed back in 1980's?
I remember a small amp that was 18w/ch that was class A.
I'm trying to recall old memories ...................

I did some contract work for Nakamichi which resulted in the
initial Soundstream amplifiers, but as I am stilled owed some
money, I tend not to highlight it. For the record, I also did some
autosound work for Adcom. They do not still owe me money.

I have the 4x30W and 4x40W models.
It's a shame this just didn't work out for Adcom.
I thought, and still think they sound incredible for car amplification... if you have the space.

I still they they are the best looking amps out there.

I have a Soundstream single rack space power amp that has a switching supply in it. Runs quite warm after a while and doesn't sound worthy of being a Pass Design.

Well, I hate to bump such an old thread but I had recently read about Mr. Pass's car audio dealings in his interview in Stereophile back in '91 I believe.

Does anyone know and specific models of Adcom or Soundstream amplifiers he had a hand in? I kind of collect old mobile amplifiers and would like to know what ones to be on the look out for ;)

....and I kind of know thylantyr lol. :D

The soundstream versions you are looking for are the A40 (class a - 20wpc) the D100 and the D200 (50wpc & 100wpc)

I can say they are all very fine amps and still have an A40 and a D200. They use Darlington pairs and are all discreet components (easy to repair)

Ah, thank you very much for the info!

Now to find one and compare it to my Carver amp :)
