Lots of love here for budget Marantz players. I once had a CD6000 KI Signature, which IIRC cost around £400 back in 2003 or so. Have to say I was rather disappointed, given the glowing reviews it received in e.g. Hi-Fi World. Perhaps my expectations were too high. Most of my listening at the time was via a Naim CD3. On the other hand my sister wanted a cheap CD player, I think around 2006, and I suggested she got a NAD from Richer Sounds for around £200 I think it was. That one really impressed me with a fleet of foot sound with lots of instrumental colour and texture, such as was lacking from my costlier Marantz.
More recently I've used an Onkyo C-7030, which is not a bad machine at all - good dynamics, resolution and separation being particular virtues. Swapping in the Naim CD5x last week did remind me that there are things the Onkyo doesn't do, however, not least in terms of general realism and musicality. Which I guess is what one would expect given the price differential.
