Hello I'm after a decent 2nd hand amp as an upgrade from my Cambridge Audio A5. Pairing it with B&W DM601 S3 speakers. I had in mind a NAD C320BEE or a Marantz KI series amp such as PM6010 KI. I'll definately consider any others. Thanks! ps I know this is my first post but I do have an eBay account with 200 100% positive feedback.
