From what I have been able to dig up so far, the differences between the Marantz CD5003 and the CD5001 are:
The 5003 has:
1. A newly designed metal/fiberglass chassis.
2. A slightly different drive mechanism.
3. A detachable power cord.
4. HDAM S2 modules. [The 5001 does NOT use HDAM modules at all].
[It will be interesting to see if the HDAM S2 modules will make the 5003 sound any better than the 5001].
The CD5003 still uses the same Cirrus Logic CS4392 DAC as the 5001, which is sort of a disappointment, considering that the CD6002, [available in Europe], uses the latest Cirrus Logic CS4398 DAC.
I would like to see Marantz design an "all out" CD ONLY player that uses the same technology as the upcoming SA8003 SACD/CD player, such as:
Rigid design with double-layered bottom chassis, Zero impedance copper ground plate, audiophile grade power supply with toroidal transformer, Zylon Loader, and Cirrus Logic CS4398 DAC, and STILL include the HDAM S2 modules...Dream on!
I bought and received another Marantz CD5001 from Crutchfield last week.
Wow, I forgot just how good this little CD player sounds!
For some reason, I think this new 5001 unit sounds better than the one I had last year! It does not sound as bright or as thin as that unit did, and sounds closer to my 8001. The numbers on the display are also a tad bit smaller than the unit I had 14 months ago.
My 8001 still sounds slightly more refined, with slightly better resolution, has a tad more sense of space, and is alittle warmer than the 5001, and maybe has better bass using cd's, but I STILL think the 5001 is slightly more extended on top, and sounds slightly livelier than the 8001.
But overall, I feel that the differences are relatively small, and the 5001 is a much better bargain, especially if you listen almost exclusively to CD's like I do.
The main reason I bought the 5001 again, was so I could compare it head-to-head with the CD5003.
I also preordered a Marantz CD5003 from Onecall last night.
They said they did not know for sure when their first shipment of these players would arrive.
I will post impressions of the CD5003, and how it compares to the CD5001, whenever I do receive it.
I will also compare their headphone jacks with a pair of Sennheiser HD650's, to see if the headphone jack output on the 5003 is worse, the same, or better than the one on the 5001.
