DIN or BNC

Posted by: Julian H on 07 January 2004

Hello all,

I use a Supercapped Prefix for my phono stage with the Naim supplied DIN to DIN interconnect into socket 2a on the 52

Is having a DIN to BNC interconnect into input 1 supposed to be better, worse or is there no difference?

Cheers, Julian

Why do you want to use input1? If you have a prefix, then it is advisable to remove the onboard phono cards from the 52....(better sound on ALL inputs) and replace them with "straight through" boards, ie converting input 1 to "line"level. I replaced the BNC sockets on my 52 with phonos (RCAs) and now use input 1 for my (non-Naim)CDP, using phono-phono interconect

My prefix/hicap uses input 2...I cannot really see any advantage in getting a DIN/BNC lead and using input 1 as you imply

Patrick.....it is fairly easy to move the labels on the 52 source select buttons...ask Naim for details.

On the "old" 52 remote (do you mean the chunky metal one with the green plastic fascia) it is quite easy to interchange the buttons

Chaps

My 52 is a late one with straight thru. boards fitted at works.

I do not have a need for a sixth input.

All I wanted to know is if there are any benefits (with respect to sound quality) using the BNC sockets over the DIN's

Cheers, Julian

BNCs have a characteristic impedance of 50 or 75 ohms and were considered to be a better match for the arm cable than phonos (cable/termination impedance matching maximizes power transfer and reduces reflections, if I remember those 15 year old lectures correctly). As your DIN terminated cable is presumably not the same as phono cable, I doubt there would be any improvements to fitting BNCs. Personally I don't recall being able to hear the difference between BNCs and phono plugs. Is that heresy?

I believe (I may be wrong here) that input 1 has the "best" power supply and sound quality may benefit on these grounds

Thats very helpful, Laurie

Thanks, Julian
