Hi there, yes you can use a Supercap to do this. The best way is with two Snaic 5s from the two 5 pin sockets (one above the other) on the SC to the upgrade 1 & 2 on the 152.
Make sure that upgrade 2 connects to the lower 5 pin on the SC.
OK. I finally managed to get the 155XS working with the Supercap. Thank you all for your help.
This was indeed an eye opener for me. The 152XS/SP was much more detailed, better highs and tighter base. It certainly revealed that the age of the 252 was certainly a major limitation in the main system.
The 252 is around 17 years old and I have owned it for 10 years. I don’t believe it has been serviced. It just stopped working yesterday after I dismantled the system to clean it up and put it together again. The naim logo lights up but not sound.
The Supercap is about 8 years old. I need to establish wether it is a DR or not. My notes show it is DR but there is no DR sign on the back.
I think a serviced 252 will bring back the magic and sparkle of the 252. Even in its unserviced state the music separation is better on the 252, it’s just that it has become a bit dull.
I would be interested to hear other peoples experience of the 252 issue and the difference after a service.
You were pretty close on my experience. If I have to choose between the 252 and 152XS in their current form, I will pick the 152XS anytime. But I live in hope that the 252 will bring back the magic after fix and service.
Sorry for the delay. I was going through some evaluations and was going to get back when done.
My 252 will take some to get serviced. So over the holidays I had a loan 252 from the dealer to test what a newly serviced sounds like against a loan 552.
And yes, as expected the new 252 is much better compared to mine. Top end is cleaner and precise and much better low end compared to 152. The sparkle is there. It is much more open, everything is more spaced out.
The problem is I have now heard the 552 in my system.
