Hifiman : Susvara vs Shangri-La Senior
Today I am going to share with you my listening of two top notch systems, among the very best... Please, note that These two Hifiman headphones (Susvara / Shangri-La Senior) and two Viva amplifiers (Egoista 845 / STX) have already been reviewed into dedicated videos. 
For this review, I have been using two Viva amps :- Viva Egoista 845 powering the Hifiman Susvara (orthodynamic)
- Viva STX powering the Hifiman Shangri-La Sr. (electrostatic) 
Beneath the headphones, we have the Meitner MA5. 
This one network player / dac is very convenient for me, for it's got a variable output level, so I was able to hook up the Viva 845 to the RCA outputs of the dac and the Viva STX to its XLR outputs. Was easy then, to set up the volume of both amps independently for the output volume of both headphones to be the same. the overall level was adjusted with the MA5's volume control.
The flutes are masking the violins’s accuracy.
The Susvara’s upper mid-range, acts as a slight filter on the treble. Comparative listening allows me to meet this point that I did not noticed until now. Which shows up that it is not so embarrassing actually. But as soon as I take back to the Shangri-La, it's much easier for me to distinguish the instruments from one another. I also have a more airy stage, with the Shangri-La. Its obvious.
Space between each of the three violins is slightly larger. I have very often praised the qualities of softness, silkiness, delicacy of the Susvara. I confirm here.
This headphone and it is true for my ears, is really splendid. So as I have often also said since May 2017,
it is still today and in my opinion, the best orthodynamic available so far, but I cannot do otherwise
since I hear it, than to note how the electrostatic technology takes the reproduction of this music beyond the limits of Susvara itself.
The silkiness of the violins is transcribed with more acuity with the Shangri-La which goes higher at the treble but mind it, its treble is always very soft, it is consistent, it is full.
It rises up very high but it is absolutely neither cold nor ethereal.
To make myself clear : I don't know any headphones so far, none, which would be able to reproduce such a pleasurable and open treble.
It radiates way beyond the note, I mean all high notes diffuse widely in space like none headphone I know of ever has.
Yet god knows how many times I have praised the splendid quality of the Susvara's treble. The Shangri-La is taking it up a notch.
The harpsichord is a bit eclipsed in the background with the Susvara while the Shangri-La highlights
it better, by offering me the richness of its pinched notes.
Here, we have from Imany, a very interesting cover of "ne me quitte pas" (french original) or “if you go away”.
It's a very nice album. One voice and 8 cellos.
When listening to the Shangri-La Sr, the strings are plucked with more vigor. Archers, who rub cello strings do so with a little more firmness of force as well. The pace is better marked.
The Susvara is a little more nonchalant but in return, it offers a slightly more voluptuous, sensual listening that I also like a lot.
The voice stands out better from the instruments, it is a little rougher with the Shangri-La, but on the other hand, it takes a very felted timbre at the low notes, with the Susvara.
So I have two cellos right and left which go completely outside the frame of the headphones from time to time, and that gives me the impression of playing outside the frame of the sound-stage meanwhile the other performers are operating in.
Although the Susvara also gives me this surprising sound-stage, it does so with a little less openness.
The transparency and exceptional speed of Shangri-La better support the performance of artists breathing a multitude of sounds, colors and contrasts into their instruments.
With the Shangri-La, the timbre of the trumpets stands rougher than it is with the Susvara which actually erases slightly from their copper tone. Once again, the sound of the trumpets at the "forte"
is more open with the Shangri-La.
Both headphone goes deap down same, but the Susvara is a bit slower and a bit rounder.
The Shangri-La hits faster, it is more energetic. Aeration between the performers is superior as well with the Shangri-La, which hits with more punch actually, with more tension.
We've all had, at one time or another with our systems, that feeling… You know… Of being in the middle of the orchestra. It has often been written, and has often been said. Well we have to listen to the Shangri-La to measure how much we can still go further than what we thought to be the best by listening to our systems !
It's amazing, frankly. At 5.33mn the orchestra rises up loud and I hear rather smooth brass with the Susvara, once again.
They regain their bite with the Shangri-La. Here again and as with the previous music, the overall openness is greater with the Shangri-La. The drumbeats are also more straightforward.
"Forte" goes with more dynamic, punch, with the Shangri-La on large groups. The Shangri-La stands out even more clearly by the fact that it gives me the impression, by its incredible acuity, that the orchestra is playing with more musicians.
So to put an end to these listenings and overall : I have with the Susvara, a very nice presentation all in finesse, velvety. A relaxing and voluptuous listening
And yes today, but this only on me of course, none ortho gives me so much music and so much pleasure. The Shangri-la is the rigor at all points. It gives me a little less softness and smoothness than the Susvara, yes, but on the other hand, it is more accurate, it is more dynamic, a little more open. It produces a little more information and a treble that goes higher, treble absolutely remarkable in terms of openness, elegance and smoothness.
I often have been telling myself that I'm very lucky to do this job. In our case, note that these two systems are served by a fantastic dac, the world class MA3
These are a slightly different, that's normal, knowing that we have here two very particular technologies, brought to their highest level.
Retail prices are very high, I think we are all well aware and we agree that it is irrelevant to speak here of any relationship between musicality and price, or quality and price, especially as taking pleasure listening to recorded music, does not, of course, require spending such a fortune.
These systems are aimed, I think, to experienced listeners, those who over time have been ableto acquire the necessary perspective to be able to measure their unique reproduction quality and fidelity.
Kindly forgive my poor English !
Thank you !
