Poor BASS with Dynavector XX2 +Sunilda + AudioNote

Thans for your comments Raul .. I feel so bad!!!

I can always add a VTA system on the arm. It exists and do not cost much ..... This will solve partially the problem.

I can also change the arm (the DPS is engineered to put other tonearms like the wilson B .... It will cost me additional 1500 $ but it will imprve).

But what makes me feeling bad is the subsonic filter on the Sunilda. If Bass starts ay 80 hz, I'm dead ...

My system is very well balanced with my AudioNote CDplayer + Dac + Preamp + Amplifier.... So I reamize my biggest problem is the prephono.

What can I do to tweak the subsonic filter (I do not know what it means ...)? If I put some NOS, will it change ??

Thanks

Dear Stelma: Maybe you can by-pass, why don't you call to the manufacturer to they can give you information how a technician can do it.

Regards and enjoy the music.

Patrick,

you should be able to change VTA on the DPS: The Rega arm should be secured with a set-screw from the side; you can loosen the set screw and lift the arm a little bit; then tighten the set screw. I use business cards to measure the distance between arm and plinth to achieve repeatable and accurate VTA adjustments on the DPS.

The XX-2 is very sensitive to VTA changes from my own experience with setting up my friends turntable. How far is the tonearm tube from parallel to record?

My friend uses a loading of around 100 Ohm into his Pass XOno.

Just curious - where are you located?

Best wishes,

Rene

Thanks again ...

Sorry, I do not know how far is the tonearm tube from parallel to record ... I have not chechek.

What I will do is the following:

1/ To check my prephono Sunilda with my friend's turntable (which is well adjusted as he own very good arm). If I have strong basses, it will mean my Sunilda is OK. Otherwise, I will contact AudioValve and s what i can do.

2/ If Sunilda is OK (this is what I would prefer), I will purchase a VAT adjustment system (available for Reaga arms ..) and I will change it.

My feeling is that this is a VAT issue, as the rest of the sound is really nice ....

Curious? I am fom France .. in Grenoble.

Regards to all

Stelma - the DPS already is designed so that VTA can be adjusted (just simply via set-screw).

Most VTA adjustment system (e.g. Riggle, Incognito) would not work if the arm is correctly mounted on the DPS (i.e. set screw from the side rather than the counter nut usually used on the Rega arm).
