CD player - release years & prices

[beelzebomb]

There's various timelines out there, but the ones I can find all stop at year 2000. I'm looking at (champagne) players from early to mid 2000s. Here's what I've found so far (based in UK):

MODEL - Cd5000
YEAR - 2000
APPROX PRICE
EBAY GOING RATE - £40 upwards (rare Phillips DAC)

MODEL - cd6000
YEAR - 2000?
APPROX PRICE

EBAY GOING RATE - £100+

MODEL - Cd7300
YEAR - 2002
APPROX PRICE - £300
EBAY GOING RATE - £90 (midrange)

MODEL - Cd5400
YEAR - 2003
APPROX PRICE
EBAY GOING RATE - £40-100 (cheaper version of cd7300)

MODEL - Cd5400OSE
YEAR
APPROX PRICE - £180
EBAY GOING RATE

MODEL - Cd5001
YEAR - 2005
APPROX PRICE - £160
EBAY GOING RATE -£40-80

MODEL - Cd5001OSE
YEAR
APPROX PRICE - £250
EBAY GOING RATE

If anyone can fill the gaps, great!

2nd hand values are curious. The 5400 is currently going for the same price (or more!) as the 7300, yet I believe the 5400 was the cheaper version of the 7300 when released. All it takes is one person to advertise it at a higher value, and the next seller takes that lead, inflating the price.

I have the 5000 (with the rare Philips DAC that gets praised in certain quarters) and the 5001 (silver, no champagne version) with a brighter, actually usable display. I can't detect any difference in sound quality.

My plan is to hunt down a 7300 and sell the two I already have. Good plan? Any thoughts or comments appreciated.
