Poor BASS with Dynavector XX2 +Sunilda + AudioNote


I recently bought a complete analogue set: Dynavector XX2 + DPS table with Reha RB300 arm + Prephono MM/MC Sunila (from Audio Valve). All of that connected to my Audio Note.
Tje results is fine (open, smooth, clear, depth ..) but lack of bass!! No sure if it is the prephono (I will change the 12AX7 by some NOS) or if is a mismatch between the cartridge and the arm ..

Any suggestion ?? Many thanks

I will continue playing aroud with cards ... but when I read the paper from Geoff, I do not understand why a single Business Card can make so much difference !!!!!

I think the single card analogy, "making so much difference", is a little extreme :)
I don't. I have an XX-1 and found it to be very sensitive to VTA. A single card is about the difference in thickness between a regular album and an 180g album. I can now see why some people adjust VTA depending on the thickness of the vinyl being played. You need on-the-fly VTA adjustability on the tonearm to do this though.
