Dagostino hd momentum, is lack of rubes a problem?


Kinda disappointing that dagostino doesnt do tubes. Is lack of tubes in their hd momentum preamp cause for concern when paired with a ss amp?

yes, rubes in title sb tubes.  Cant edit descriptions. So rubes appears.

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

Love analogy.  I am not tu smart, pictures make it easy.

so driving uphill toward higher impedance is good. Speakers are on hilltop and source is at bottom of hill

like a high altitude with lower air resistance, ie. why jets fly high in air. Signal path gets alot easier thru all the circuitry and cabling as it flows toward speakers.

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!!

I’ve heard the d’Agostino different times with the Sonus Faber speakers : not my stuff: there’s no emotion in the music , very “flat’. ( sorry for the lovers…) detail  and placement are okay, but very expansive for what it is : much beter are Ear Yoshino , VAC , Wavac. , …here you can find emotion : you are “one”  with the music ( you experience ). You don’t have that with d’Agostino…
