Naked pictures of Pass

Pass Picture(s)

The Stereophile article was the first introduction to Nelson Pass (I think). I became a fan there and then because he talked about being a topologist. He studied, thought about, designed circuits with the goal of simple topology. This made sense to me, and I have followed his work and enjoyed his wit and wisdom along the way. That he would share his work with people like us is remarkable. God Bless Nelson!

The Stereophile review was inspiring as well. Here's the best part. I never seen anything like that regarding Gaincard.

aleph article

I have saved this issue because of the article. Forgive my ignorance, but what is a gaincard? Also, I wonder what the differences (sound wise) are between the Aleph 0, and the Aleph 4 that is nearly completed. I am hoping for great sound. I will drive Dynaudio Gemini's from 250 Hz up with it. Any opinions out there?

Gaincard is an IC based amp which started the gainclone frenzy http://home.student.utwente.nl/f.s.bouwman/audio/thor-amp.html

Aleph 0 supposedly has better control into difficult loads, but subsequent Alephs sound even better, because having less stages they should be cleaner .

 

[nobody special]

"With an apparently huge damping factor and upward of 50 amps of peak current waiting in reserve, the Aleph dished out bass lines with an iron fist."

I wonder what Aleph this reviewer was listening to...
Isn't the Aleph limited to twice it's bias current?
Reviewers... you gotta love 'em.

 

[Peter Daniel]

It was Aleph 0, of course.

That review sold me on Mr. Pass and his amps.

Just this month i got my first Pass product, an
Aleph 3. worth the wait!

Now i'm collecting parts for a ~5watt SOZ.
And will finish the Zen V1 that i started 5 years
a go, now that i've found this Forum and the
proper heat sinks!!!!

I came into this thread thinking about
"pictures of naked Pass"

I was wrong

 

[jacco vermeulen]

JH,

you're not looking right.
Pass is lying underneith the X600.5, all naked.

Was just browsing through this thread when I finally discovered the provenance of the 2 huge hestsinks I’ve been hoarding since I found them halfway to the door while cleaning up after the first Burning Amp! Clearly someone got them at the parts raffle, then rethought carrying them blocks and blocks to their car. They are heavy!

Mystery solved.

This X250 review, I posted some time ago, also contains a few cute pics

Here is what I looked like during the pandemic.

The meaning of "topless" after the pandemic will be "without mask".

 

[wirewiggler]

Need to find mask with Santa Claus beard attached for Mr Pass. He will be Santa Paus for Burning amp 2021 ( with bag of Vfet amp designs).

My humble bench awaits, and I have tried to be good but these stupid Roon endpoints keep sneaking up on my bench.

We had him wear a santa hat at the first BAF while he gave out the free parts he brought. He may still have it!

OK now about me me me! what are suggestions for what Pass amp to build with those monster heatsinks there is the link to in Post 32.

I have a couple of F-5's so I don't think I need an F-5 Turbo. Thinking on something more single ended based. But whatever..
Then I'll post a naked photo of the insides here when it's done.
