Marantz CD6007 DAC question

[kramer2020]

Hi, I'm thinking about getting a Marantz 6007, however it would be located approx. 5 metres/16 feet from my Marantz PM7000N.

The simple solution would be to connect it to the amp using optical toslink and use the CD6007 as a transport, but I'm not sure if they both have the same DACs or if they are different and one is better than the other.

Alternatively I could just make the CD6007 work for its money using its onboard DAC and invest in a 5 metre pair of analogue phono cable, but would this be a bad idea?

A quick google suggest the amp has AKM4490EQ while the CD has AKM4490. Also thanks to Google, they are use the same technology but the EQ is an updated and improved version.

I have no experience of long RCA cables but believe the consensus is around three meters is the max you should go. It looks like optical is your best bet.

Following on from the above, the What Hi-Fi review pages advise:

- The PM7000N uses an Asahi-kasei AK4490EQ DAC

- Our initial sample of the CD6007 was equipped with AKM's 4490 DAC chip, but a fire at AKM's factory in 2021 limited supply to the point where Marantz was forced to find an alternative. That alternative turned out to be ESS Technology's well-regarded ES9010K2M DAC chip, and from May 2021 all CD6007 players produced use this.

I’ve used RCA over 5 meters before and it was fine. Personally I would try both options and, if you can hear a difference, stick with which one you prefer. (Also remember the CD6007 DAC has 2 different filters you can choose between).

Both types can be picked up for not much outlay (just examples):

I have a NAD CD player connected to a DAC that is sited under my tv. From the DAC I have a 5 meter run phono lead connecting to my amp. When I compare the sound to another cd player(Marantz CD6007) that is connected to the same amp with 50cm phono leads there is zero difference in sound/volume/clarity.
