Denon DP 300F DL-A100

[neaman]

Hi,
I am new to vinyl world, but not to music. Here is my setup for vinyl:

DP-300F with DL-A100 cartridge
AU-300 CL Step-up Transformer.
Onkyo A9000R Amp. (it also has built in phono stage)

I have these problems:
1.Rumble while playing.
2.I want to use SUT and DP-300 d'ont come with GRND, but my amp has GRND post.

3. Should I buy dedicated Phono Stage, I am considering Parasound Z Phono USB and Pro-ject Phone S (the new one).

4. Sould I consider buying Otrofon blue / bronze Cartridge , with Dedicated Phono Stage.
5.What is Record Clamp , should I use it ?

You need better turntable and tonearm to make the Denon DL-A 100 perform to full potential.

Thanks for reply, can you suggest any turntable.

[KentT]

Ortofon is OK. A high output Denon MC like the DL-110 would be just fine in a DP-300.

Kent, when I post for help first, you suggest ,better turntable and tonearm to make the Denon DL-A 100 perform to full potential. When I ask you to suggest for Turntable , you reply with suggestions for Cartridges.

Here is my current update, bought Pro-ject Phono box S and Ortofon Red.
You were right Orfoton is OK.
But when I setup with Denon DL A100 - AU-300 CL Step-up Transformer and Pro-ject Phono box S, what level of clarity and sound stage I am experience is now I never experienced before. The rumble is gone after I used Pro-ject Phono box S subsonic filter feature.
