Impedance Loading for SS Hyperion


"470 - 1000Ω" says Peter Ledermann. My phono stage offers 400. 800, 1,200. so I used 400 initially (extremely smooth), decided 800 was better (some edge present) and 1.2k even better still. There is one higher setting allowed for the MC input (along with several lower ones), 47k. So I’m trying it, and I like it. I keep swapping to the London Reference I am comparing the Hyperion to, and it seems the higher the impedance loading, the closer they sound. I am not experiencing the "peaked high end" I was warned of if loading is increased over 1000Ω.

Maybe my half a remaining ear (thanks, streptomycin!) simply can’t hear the cartridge screeching. Might work for others with high frequency loss? I think the issue is that I have a powered sub that is making sure I hear some bass whatever the loading is set to. If I turn it off the Quad 2905 speakers alone don't sound as if I'm listening to the full range of sound. Perhaps I should set the loading without the sub, and then do my usual procedure of setting the sub volume so I cannot tell that it is switched on, but all the same things sound better?

ChatGPT, others, and listening to the different settings, all point to 47k ohms.  Set yours to your preference.  I do not tell other people how to drink their whiskey.

But you just did.

The designer and manufacturer of the Soundsmith cartridges recommends the following

Hyperion ( early ) 470-1000 homs

Hyperion ES greater than or equal to 470 ohms.

Chat GP is great for finding out how men can have babies, not so much for audio.

Of course you are correct in that folk can do whatever they want. high end audiophiles have a proclivity for knowing more than the designer. I recall a customer who insisted on driving Apogees with Luxman flee power valve mono amplifiers.

It ended up with an early Guy Fawkes celebration, but , hey , he reckoned it sounded great for the short period it ran.

 

 

Six hours of driving tomorrow, but at the end of it I should have my right channel back. I've ended up preferring listening to one tube amp and one speaker rather than the old YBA-1ɑ. And no hum that I can hear!

@dover. You can set yours at 470 ohms.  I will set mine at 47k ohms based on how it sounds to me on my system in my house.  You vastly underestimate how useful ChatGPT can be in this area.
