SuperLine Loading Thread.

DEfiniely get the big counterweight!

Its entirley right and proper that Tikitoki will need a different loading to xv1s

Do you have to Jon?!! Makes me feel all inferior when you use that term - Corgi or Dinkey version of the real thing!!

Peter

how about Kiri Te Kanawa? Is that better? :-)

According to the specs, a Rua weighs in at 8.8g and XV1s at whooping 12.6g.

At what weight, the factory recommend to use a heavier counter weight on ARO?

Is this a cartridge dependent thing?
I would thought that you can get away with a normal counter weight with a Rua.

Just put the system back together after saturdays Massive meeting

and had the 453ohm plug ready, courtesy of Dr Superline and Dr Peter

Oh

My

Gawd

it all came back -- the huge depth, the vast imaging, the clean sound, the music making.

sorry guys, but The Massive was massively shortchanged on saturday by the 470 plug...

you know where to visit... :-)

FYI the 453R is working better than any other loading on Geoff's system using XV1-s SME V and Raven Gorby Orbe plus!

Other loadings tried: 500R, 470R, 442R and 430R.

Kind regards,

Peter

How fascinating -- its almost as if the XV1S has a "resonance peak" at 453ohms loading.

Is Peter there with a SuperLine ?
Do I detect a future change in the making ?

I picked mine up on Saturday afternoon - listened to one song - and then had to go out for the evening.
Brief listening on Sunday and then an extended session last night.
Words cannot explain what I am hearing.

Have fun.

Gregg

.....Ah we will have to wait and see....still in testing

Speaking of loading details:

453R No capacitor ..... sounds excellent on my Orbe / SME V / XV-1s

Finally got back to looking at the loading for my Koetsu Onyx after trying the Airtight PC-1 which proved to have too high an output (0.6mV spec) for Superline.

Long story short - 153R gave me a flavor of what all the Graham/Continuum etc guys presumably like which is the lush midrange but for me everything else is wrong, timing off, no frequency extension and so slow it makes my head hurt. So I went to 500R and 1nf (Proche/approssimazione/Entspricht ungefähr/approximates to Naim 'K') and everything is right with the world again - boogies, waltzes, swings, sparkles, resonates, sings etc. So as a generic MC starting point I believe this is it. I'm convinced that whoever came up with the 560R/1nF load in the first place got it about right. If Steve Sells is reading - thanks for a wonderful phono stage and please update the entry in your spreadsheet. Also Helikon Mono is now a "no plugs" 10k/100pF.

I'm still on the 220R/No cap.

The one thing I've learned with the Superline is that the system no longer worked well with my beloved Nait 3R. Or even with a NAP 140.
The Superline is so open in that now I hear the shortcoming of the amp too much.

Hi Kuma,

Which cartridge?

Gee, could you actually hear it overloading, with distortion and/or flattened dynamics? In the overall MC scheme of things, that's not such a high output level...

Jeremy,

On the Miyabi/47.

I find the same little blighters but in another "load plugs".

In my 500R plug I find 1,1K ± 1% resistor (according color codes) and in my 5,6nF plug I find 4,7nF capacitor!

The right resistor is in my 1K plug - 1K ± 0,5%!

The label shows the value of the component inside the plug - the truth or not the truth ...

I wonder it's because to compensate for the Superline's internal loadings?

Yes Kuma, but in the rest of plugs the label shows the value just as the component inside - 100R,220R,1nF and 10nF.

ah..

Well, it might be a screw up then. ( which I suppose can happen )

But then all of the cartridges used in this thread so far have less than .3mV. ( or right around there )

So comparatively, output of .6mV is double.

True enough Kuma, the general discussion has been about lower output cartridges. However, there is a general trend among even very expensive, highly-regarded cartridges for higher output than before. You can see this in many Lyra, Clearaudio, and Benz expensive cartridges, for example, and among the mid-price offerings of Allaerts and Koetsu. And certainly the Air Tight is regarded as state-of-the-art by some.

To me, the interesting question is, what is it about the Superline--and Naim phono stages in general--that makes them work only in a narrow range of cartridge output level? This is not the norm in the genre of expensive phono stages.

aht,

There might be something else going on besides the output voltage.

Transfiguration's Orpheus also worked well with the Superline and this cartridge has a similar output voltage to the PC1. (0.67mV @ 5cm/sec. 1kHz )

So, the argument of the Superline only works with a narrow range of output voltage is somewhat out of window there.

I think we need more data to conclude.

p.s. I just looked the specs for the Akiva.
It's at .56mV @ 5cm/sec. ( the written spec is given at 3.45 cm ( probably a typo there ), so I did the conversion to match the rest )

I also assumed that original PC-1's .6mV is figured at 5 cm groove velocity, but if it is measured at 3.54 cm, its output voltage is now 0.42mV.

Kuma,

That's pretty interesting data; you're right, there may be something other than simple output level at play here. But I'd still like to hear JeremyB's report on what he heard with the Air Tight/Superline combination.

FWIW, for the first two days my Superline, hooked up to a XVI-s, sounded like it was overloading. That effect has subsequently disappeared.

aht,

What's the rest of your system?
And what loading are you using?
