Superline load plugs

Posted by: Neil H on 12 March 2018

Hi to you all,

This is my first post on this forum, so here goes.........

I have recently purchased a Superline and like most of us out there I read many threads on the subject of load plug selection for the best performance of the phono stage. I narrowed the selection of plugs down to two resistive and one capacitance 500/560R and 1pf

The results were impressive but could not decide on the better resistive plug however I started reading the threads again and learnt that Peter Swain of Cymbiosis had carried out many tests with various loadings in particular 576R and 740pf 

I spoke to Peter on several occasions regarding the listening tests and results of the two plugs he had conducted in the past. A little while later I now have the Air plug 576R and the standard metal bodied plug 470pf and have to say Im thrilled with the difference they have made on my system it was well worth the purchase. There is a further upgrade too but will leave this for a while and just enjoy listening to what I have.

To finish off my ditto I have to thank Peter for his advice, time and efforts and ultimately  acquiring the plugs for me to purchase, from the first phone call Peters advice and contribution has been phenomenal to which I thank you greatly. 

A very happy superline user

Yeah Peter fixed me up with the right plug.   Sounds great.

Ditto with the Cryo Air plugs 453R and 1nF for my XX2Mk2.  Thanks again Peter!

Air plugs for me too but care if Julian at Audio T in Brighton

Out of curiosity what cartridge are you loading? I've been playing around with different loadings on my Superline with a Linn Krystal on a 560R and 1pf vs. 576R and 1pf. I personally preffered the 560R and 1pf. I thought it had a little bit more weight now I'm thinking perhaps I should I be trying a 576R and 470pf?

When I bought my Superline, a very nice nearly new one, it came with a deep cryo AV options Z foil 100R Air-plug. Does anyone know if AV options offer part x deals against 560R version of the same plug?

Another happy user.

The loading will all depend on yoru catridge.
There is no universal loading for the SuperLine.


For the SuperLine Naim generally recommend X10 the output impedance.  That’s how I use mine, with Rega’s Aphelion.

hmm, I use 100 times the output impedenceon a T Proteus, still only 100Ω, and I’ve recently added 470pF following an arm change.

According to the Superline manual a 560R and 1pf is the equivalent of Naim's 'K' boards and I believe if you substitute the 560R with a 460R this is the 'S' loading?

Maybe some linn cartridge owners could suggest what they find as the best Superline loadings?

For my Kandid I use 576R and 1nf Airpligs with the 576 deploying cyro treated Z foil from AV Options (U.S.A.).

in the passed I could not really decide between the 560R and 576R as both had their own merits and I kept switching between the two. I finally settled on the 576R and have never looked back.

I have toyed with experimenting with and without the capacitance plug or trying a different value such as 476pf which I have heard some people have tried but I have not gone there.

Also, worth looking at this old thread:

FF, all,

I was about to post something along these lines myself. I had a look at the link there and the thread was closed March 2010. I don't know why or if it ran our of steam but I'm sure there a lots of cartridges out there still needing fettling.

I had a good look around here and on the web. There seems to be lots of electrical explanations which I don't understand. I was looking for some rules of thumb over the 10x rule.

I am trying to load an Apheta on a RP8 with Supercapped Superline. Right now I am on 100R and 4.7 nF. This after much faffing and it works for some records but not all.

My own rules so far are:

Faffing is ok and you are not likely to break anything.

Let your ears decide. I can thank another pair of ears for my setting at the mo.

Too little R and bass can get flabby. Too much and it can get screechy. Yop end that is.

If screechy, a bit more capacitance load can help but it can all get a bit muddled.

I was wondering if anybody had found the sweeet spot for the Apheta?

Sorry to hi-jack the thread but it seems the OP had found his settings already.

I use my RP 10 with an Aphelion  (same settings apply for the Apheta). I have the Superline set up with 100 ohm load and 1nF cap. 

This matches the settings from my Rega Aria and follows the 10x output logic.

Load plug value may depend on turntable and arm combination. I found that i prefer  100R  on Superline for my WTL/Dyna XX2 than universally recommended 453R.

Hi Adam How do you power your Superline? Looks as though you may do it from the 252. Do you use SL IC and if so does it also carry the power? Sorry for so many questions. What difference from the Aria did you notice? Thanks in anticipation.

I recently settled on 220R/470pF for an Ortofon SPU Royal GM II.

Am also using 470R/470pF for an EMT JSD6.

In the past, used 453R/no cap for a DV XX2.

Currently off the back of my 282 (252 is hooked up to an LP12). Once a dedicated Burndy cable arrives, it will be powered by a SuperCapDR, and connected by a 4-pin DIN > 5-pin DIN HiLine.

Find a load you like but avoid the capacitance plugs if you can.   They muffle the sound at my house.  

Posted on: 14 March 2018 by Richard Dane

On my own RP10 and Apheta 2 I have the Superline running with 100R and 1nF.  Admittedly I started out that way on the basis of other recommendations, it sounded really good, so I haven't messed about with alternatives yet.  However, I have been advised to try 220R and see how that goes.  And also to try without any capacitance.

I will try for myself but in the meantime any other observations and findings out there on not using a capacitance plug?

Hi Richard -

I prefer the sound with no cap plug (internal only). 

Am only adding capacitance when RF is present. This seems to come and go in my location. Had Radio Moscow many years ago, followed by a long stretch of silence. Then, last year, noticed a bit of RF hum, but it was easily silenced with 470pF.

Anything above 1nF sounds a bit dumbed down to my ears, but I realize that every setup and location differs.

ATB.

Will do some trials this week and report back.
