Hi Shiggins

I loved the 18 bit 5ks when I had them. A really superb upgrade is to do as Chris suggests... add a 518 'processor'. It offers a very organic and fluid sounding upgrade and is a must with 18 bit 5ks IMO.

Back in the day I had two 518s to cover L,R & C duties from a Meridian 561 AV processor. I ran Meridian 602 and 500 transports directly through them too; a cracking system.

If no one here has a 518 for grabs, there's one over on pfm at the moment. I should add that I have no connection with the seller.

Cheers

George
