NAC32.5 Boards

Can anyone advise what the purpose of NA328/1 boards is in the phono stage?
Regards Bob

See the FAQ here:

NA328 boards are pretty much obsolete these days as CD replay has improved markedly since they were available. Naim recommend they are replaced by NA326 link boards.

As mentioned these were naims good idea in the early cd days. If you are using the input for cd or another line level either replace with 326 boards ( near impossible to find,) or link out/ replace the original link. Or, you can add 322 or 323 boards for an extra phono input.

The 328 boards were also know as ‘V’ boards - for variable. My 1st 72 had 2 sets of BNC inputs - one had Phono boards (323 K, I think), the other had 328 V CD boards. Adjusting the pots on the V boards gave a near match in level between CD & LP.

328 V’s are probably quite a rare board now. Do not throw away…!!

I think the 326 Link boards are the only variant of the 3xx series that I have not owned - ever…!

Not owned naim 326 either. Although i do have a pair of err, third party versions. A bit pointless really. Darran makes up short removal links now ( if asked) when 32s and 72s go for service.
My older 72 ( in service with a HC and 250) has these removable links. My son’s 72 has the wire links refitted and my daughter’s p72 has a 323e fitted to handle her Rega P6 and DV10x5. Forgotten id bought 3 72s.

Thanks all for replies but not sure why " don’t throw away " ?

I guess because these days anything Naim that’s getting on for vintage is deemed “collectible” by many.

@BOB59 - Or - might be useful to others… That’s what I meant.
