Denon 103R or 304?

When both in stock form, the DL304 is a better cartridge but when the 103R is installed in an aluminium body with a heavy arm, then the 103R will become the winner.

what Kcc123 said. but with just minimal mods the 103 starts to overtake the 304. put the same amount of money into the 103 as you would pay for the 304 and you have a much better cartridge in the 103.

The Denon 300 series does have a decidedly different sound than the 103 series. Personally I prefer my SS retipped DL-103D to any of the 300 series but that is my preference.

Compliance wise both cartridges will work with the RB300. I have run a DL-103R in my modded RB-300 without any issues.

The issue I don't see anyone addressing is that the DL-304 is a very low output MC cartridge (0.18mv). The Parasound ZPhono is supposedly OK with cartridges down to 0.15mv but I would be asking what the S/N would be with the DL-304.

It could be perfectly OK but if you end up with too much background noise it will kind of spoil the party.

The medium mass Linn Basik tonearm on my Linn Axis is a surprisingly good match for the 103R. I go with the 103R assuming your tonearm is similar mass.

I'd go for the 304. I've owned both in a modified RB250 and the 304 is CLEARLY far superior in every aspect, BUT the real consideration is this...

DL -103R = 0.25mV
DL -304 = 0.18mV

Unless you have a REALLY quiet phonostage with bags of gain forget the 304...seriously

I use my 304 with the whestTWO and it is great, ultra quiet with PLENTY of gain with a great soundstage and great musical resolution.
