Denon DA 307 and DA 309

the DA 401 is an arm dedicated to light cartridges therefore only moving magnet.

No, look at this Denon catalog, this is DA-401 tonearm with MC cartridge DL-303

This tonearm goes with two different counterweights for MM or MC and can be used with both types of cartridges.

Here you will find it with classic DL-103 series (higher compliance version for sure).

better this way

I would like confirmation if your DA 307 also oscillates so little.

Not my case, mine oscillates more than the one in the video, go to my link and watch the video https://www.dropbox.com/sh/m6j01m72nt9v5tl/AADVZPzl_uly7MJldNR_nT9la?dl=0

@luisma31 many thanks ... I will show your video to the lab for them to double check my 307 which does not persuade me a good job is done.

Does it have any movement in the horizontal bearings or is it fixed well?
Has your tonearm ever been overhauled?

Just noticed your response, seems I wasn't following the thread.

There is no horizontal movement, if you engage the antiskate yes it moves outwards as it should, the tonearm hasn't been overhauled.

As a matter of fact I'm a little disappointed, the initial test and sound wasn't anything good, I think the Zupreme headshell with the DL302-II is too heavy for this arm so I will be getting a lighter headshell and MM cart and will try it.
My former Technics SL 1210 mk5 sounded better, but I'm sure it is the lack of experience setting up everything so I'm not quitting.
