Pass Labs Int-25 review in Stereophile

[2 picoDumbs]

The only thing new is the volume control and input selection. no need to rehash xa25 circuit info.

What is used to control volume?
Is it the muses chip, or regular potentiometer?
What relays or switches are used for input selection?

a very enthusiastic review by Herb Reichert. He mentions that he likes it better than the HPA-1 - XA-25 amplifier combination. Smoother sounding or some
thing like that.... I wonder what topology is implemented in the front end to make that happen.

Seems I am blind, I cannot find a review of the INT-25 at Stereophile from Herb.

😱

Here's a little snippet from the INT-25 page on Pass Labs's website:

The XA25 amplifier section is direct coupled requiring no DC servos or frequency compensation

And the Specifications say, Frequency Response: DC to -2dB at 100 kHz.

Let that sink in for a moment. Requiring no frequency compensation.

I see probably one gate stopper for the right puck on this picture from 6moons about XA25 ......

You don’t need gate stoppers at all they connect directly to the leprechauns.

oh, I see someone like this makes the sound in the XA25....

If Nelson or Wayne would just post the official schematic here, it would
put a stop to all the annoying questions....

...they connect directly to the leprechauns.

Some other designers use cats.

Cats are easy to come by; leprechauns are unobtainium. 🙂

The Int-25 looks like an interesting piece. I wonder if the local
dealership here has one.

 

[Zen Mod]

you're addicted

[Dennis Hui]

Nah....just curious. 🙂

Hi Dennis, Which dealer in Toronto has Pass Labs products? When I queried last year I believe I was told there weren’t any authorized dealers here.

You can try this:
Pass Labs | Products that invite you to listen

It seems it traces your location. I got a Danish name and link.....but link was "broken" so probably no dealers in Denmark for the moment.....

Hi JSA, I sent you an email.

It was just a web page error…...to be corrected by PassLabs webmaster:

This link shows up for Denmark.....the first part has to be removed:
Sorry, this page isn’t available | Pass Labs

Herb Reichert writes Wayne made the small 6dB Pre section in the INT-25.

So it could be a half UGS without cascoding.

:--))

 

[Zen Mod]

.... piece of cake.....
