Dagostino hd momentum, is lack of rubes a problem?

How much is lost if one chooses DAG vs what a tube pre has to offer?

Can anyone speak to this potential DAG shortcoming?

Your asking a question, then answering by asking/stating the answer with another one???

My answer to you is, "if" the DAG preamp was bettered by a tube one, it’s because the tube one was coloring/masking something else in the system (source/s) that wasn't to your liking, and the dag pre showed them/it up like a microscope, it would probably been even similar or more also if a passive pre was used.
I suggest it could be your source/s as you use a lot of HT processing and movie stuff which let’s face it🤢

like a high altitude with lower air resistance, ie. why jets fly high in air.

By jove, me thinks he’s got it👍

Imagine 4 lanes of traffic now going into 40 lanes, yahoo time to put the foot down!!

So why do ohms ratios increase from source to pre and then to amp and then to speaker.

thanks

Output should be low, so they can drive unimpeded into high impedance.

Imagine a traffic jam caused by 10 lanes coming into 1, that’s like a high output impedance looking at a lower input impedance, 10:1 not good.
You want the opposite. 1:10

Cheers George

Is that output imp on preamp side and input on amp side?

never have understood impedance

Source output impedance to pre input impedance, and pre output impedance to amp input impedance (and to a degree, amp to speaker as well)
All need the 1:10 or higher ratio

(1000ohm = 1kohm)

So a source with 100ohm output impedance is good into pre input impedance with 10 x that, which is 1000ohms. (1000ohm is referred to as 1kohm).

Cheers George

So confusing
is impedance matching meaningful? How does it work?

It said but undocumented and I agree, to use a minimum of 1:10 min ratio. (output impedance into input impedance) 1:20 even better

Cheers George

then spend the farm on a nice ss pre.

Why spend the farm on a pre.
Like I said if you need to color the sound to your liking with a tube pre, you don’t get off on the sound of your source.
Better to change the source to one you like.

If you don’t change your source get a $49 Schiit Sys passive pre after it.

Then the Sys into the $299 Schiit 6 band Lokius EQ, and it to your amp

jumia OP
Is lack of tubes in their hd momentum preamp cause for concern when paired with a ss amp?

It’s the designer’s choice! Tubes or transistors - either can make sonically excellent circuits! The disadvantage tubes have is that they age and need replacement.

It’s simple and should be.
One has more distortion and colorations, the other has minimal.
The one that will be "truer to the sound of the source", will be the Dan.

And if you don’t like it, "you don’t like the sound of of your source".
So change the source and get off the merry go round, otherwise all your trying to do is re-mix tonally the music yourself.
If that’s what you want to do (re-mix), save your bucks and get the new Schiit 6 band Lokius EQ
