Gotta say, the hypsos is one nice unit. My use case is kinda niche but the flexibility is very nice. I use it to provide some clean power to an external ssd where all my music is stored which is then connected to the streamer.
It still boggles my mind how changing the voltage also alters the way my music files sound. Lower voltage is generally more rich and weighty, higher voltage is generally more dynamic and punchy. I settled on 8.4V as it has the best balance of both (accepted range of device is 6.5V - 9V), it’s subtle but it’s there. And you were right @dB_Cooper the sotm hub responded well.
Now the only thing left to do is up the DC cable game going from the Hypsos to the sotm hub. I see brise makes a specific cable for the hypsos so I’ll probably go with that soon.
Oh btw for you Hypsos owners, do you leave the SSM and 4TSD options on out of curiosity (top left of home screen)? Haven’t gotten around to playing with that yet…
The Hypsos has only one voltage output? I know it’s infinitely variable but can you get two separate voltages from that one four pin connector with a dual cable?
But it will be the same voltage, so if you use something like that you’ll need to make sure both devices run the same voltage. If you want 2 full power outputs with separately adjustable voltages, you just need to buy another hypsos
That makes sense. It’s likely a great unit given how much it elevates the sound of the amp from what I’ve read. I’m just done buying single voltage output PS. Shit can get expensive!
So now more details are published. Nothing I’d be totally suprised by new (another) Sabre/ESS9038Pro DAC. 2.8k€ pricing sounds okay, but in this DAC-niche are a lot of competitors.
Not sure why they haven’t integrated some Streaming bridge, than it would be for me a real Lumin killer-peace.
What makes it interesting that he mentioned that they have joined forces with software developers from HQPlayer/Signalyst and provide NOS/Sabre Filtering.
Hey guys, i own the ORR + HYPSOS for almost 2 years now and i actually never really tried to understand the differences in sound that changing the voltage can bring.
I am playing with it now and i have a question. Does lowering the voltage increases the current in the OOR’s output? Or it merely increases the current provided to the OOR?
The reason i ask is i read that, for planar sets, we should set the HYPSOS to a lower voltage, so the OOR can deliver more current. Not sure i am convinced about that though…
That’s not really how current works.
Current is pulled by the load based on the output voltage (read volume) and the load itself.
The input voltage will change when the amp clips, and probably the linearity of the output amplification devices, but unless it significantly changes the output impedance (which I doubt) or the Hypsos can’t deliver the current demand (again doubtful) it wouldn’t affect the output current.
If the Hypsos itself was the limiting factor, and it could deliver more current to the OOR at a lower voltage, but again I doubt that.
I don’t doubt it will sound different, I’m just not sold on the explanation.
In my experience with the OOR/Hypsos I did experiment with the voltage settings early on in my ownership and with the Susvara, at a lower voltage @22 iirc I found it to have a bit more impact and a slightly warmer shift overall but at the expense of some detail and speed. Not a lot but noticeable to my ears. Raising the voltage tightened up the bass and I perceived the amp to be all in all a little more quick and with more detail present, but for me it was not as natural sounding.
I also found those adjustments to produce similar effects across different headphones - though some headphones were more reactive to the changes e.g., My TH909 was really responsive to the positive to voltage adjustments but I bought the Ferrum amp stack specifically to work the Susvara SO in the end I just went back to the nominal 24v setting and have left it ever since. For me its the best sweet spot.
To provide some context - the DAC I use with the Ferrum stack is a Holo Spring 3 KTE and on the OOR itself I leave it in the middle gain setting ( 0 ). At that setting and the Hypsos at 24v the timbre is very much to my liking the dynamics are good and the Susvara sounds to me really good - better to me than it did with the Bliss amp with the same DAC in line. All of that though is subjective and biased towards my preferences.
I’d say give adjusting the voltages a go - but make a change and let it sit with you for a week or 2 to give the subtleties of the changes time to register with your ear. A quick A/B won’t suffice IMO. I like the fact that I can change the voltages to fine tune a bit of the “last mile”, the voltage setting to me are like the dip switch settings for gain on my Violectric amp - nice to have when you need them but not something you fiddle with daily.
Sorry I went way off coarse, but I hope there is some value… What I should have just said was I don’t know if it raising or lowering the voltage is impacting current output I’d assume that lowering the voltage was raising the current output some because of how the Susvara reacted to a degree - but again that’s subjective.
100% agree, i cannot really tell if there is a difference when i A/B, these small changes are only really perceptible to me if i spend a few days before switching back.
Pretty similar experience for me as well. Lowering the voltage equals warmer and smoother presentation. Cranking it up equals dynamism and leanness. Finding the sweet spot is key.
My use case is totally different though, I use the hypsos in the digital side rather than the analog side.
