Parasound's Hint 6's new volume control provides huge sonic advances?


Promotional language for the (relatively) new HINT 6 says this: "New Burr-Brown Volume Control:
The Parasound HINT 6 is packed full of technical advancements. The new, upgraded volume control replaces the original model's motorized potentiometer and sliding mechanical contacts with a Burr-Brown electronically controlled analog resistor ladder volume control. Technical advancements in the new volume control offer a more distinct sound stage by increasing the dynamic range, lowering the noise floor, improving left-right separation and maintaining absolute left-right channel tracking at any volume level."

I'm not a skeptic, but am trying to learn.

QUESTION: How does a volume control affect so many elements important to the sound?

I almost never look to the details of how an amplifier's volume control is designed. Is it this important?

No resistors in the signal path.


Must have something? Unless it uses the constant (high) "output resistance" of the stage before the volume as part of a divider to get shunted to ground.

The Lightspeed Attenuator, made by George, was probably the best volume control I have had in my system.
Thanks for the rap.

 
Im not sure why it isn’t still talked about and used by some of you
Haven't sent one out of Australia since the start of Covid Feb, we shut down with the "Covid thing" very early with imported/exports parts to make them with, and with the export of the final product.
I still won't send one OS as the last one took 4mts to get to the new owner in the US, he was happy in the end but quite upset during the delay.

The 128 step relay switched volume control in my Schiit Freya is great, it preserves an accurate channel balance, and you’re never stuck in the "one click more too much, one less not enough" zone. The pleasant clicking sound it makes reminds you that it’s there.

Hey Wolf, you can get the whole thing 256 step passive in bal or se from this guy.
And if you search eBay you can just get the kit form without chassis as well.

He's got it all, a real player.

I appreciate learning that, and it will be interesting to see whether this feature is really an advance
It’s about as much as a sonic improvement over say, the likes of an Alps Blue Velvet (-80db channel balance) as a Dact series/shunt switched resistor volume control is.

Nothing to write home about Burson Audio been using them for ages.
