Graham Phantom DV XV-1s setup question


I took the plunge and moved from a DV XX2 MkII to the DV XV-1s :-) My TT is the TW Raven One. I have been playing around with the setup and currently have the loading at 100ohms, VTF 1.87gram, no anti-skate and no damping fluid.

After doing some searches read about the 2.5 tracking force option. I tried it at 2.20 grams for a couple of days and briefly at 2.50grams and it seemed to kill the dynamics. What I am experiencing now is slight thin/bright sound on some recordings, not what most people report as the character of this cartridge. Moving the VTF seems to kill the dynamics.

I've only had it now for 3 weeks, 20-30 hours. Is this the breakin character of the cartridge? is anyone using the damping fluid with this cartridge? how much if you are? Ideas? my phono stage can do 30,100,500,1000,47K.

Thanks!

Doug,

Thanks for the info., I'm new to vinyl so I'm relying on others to do the set-up. Info. like what's in this thread greatly assists me in learning.

My friend spent some time last night setting it up, in the end he seemed to be having issues with anti-skating and the arm wanting to move outwards when dropping the needle. Didn't really get to spin any vinyl just too late and not properly set-up, he did put on a pce that I had not heard before that he uses to test and at that point made reference to saying you will need to hook-up the Audia Flight because there isn't enought gain in the VAC phono. At this point I did not question him because he wasn't done and I had no reference to base such on, he is coming back tomorrow and once set-up and if he feels the same way I'll ask, hopefuly get to hook-up the Audia Flight and hear what he is talking about.

I have plenty of SPL's with my RedBook line stage, most recordings I listen to the volume at set slightly before 9 and slightly above 10 o'clock.

My speakers are MBL 101E, amps are Bryston 28 Squared mono blocks.

I called VAC today and spoke to Brian, apparently I have it hooked up correctly otherwise I would not hear any music. Two dials on the back for phono section, one for switching to either MC or MM and the other for load. Brian said if I need more gain 6db is available by changing some jumpers and wires inside which of course involves sodering etc.,my preference would be not to do this.

I asked Brian which carts he feels are ideal for the VAC and he mentioned any which are 0.7mv, big difference from what I have at 0.3mv.

I await to see what happens tomorrow and will post the results.
Too early to draw any conclusions. lets finish setting up the arm first. We're only 1/2 way through only.
I'm not gonna argue w VAC but I will also tell you that my VAC Ren Mk2 phono stage has more than sufficient gain for a 0.3 mV LOMC. I'll also tell you that the KAB phono pre-amp calculator shows 62 dB (which is in fact the spec for gain for the MC input for a Ren mk2) to be optimal for 0.3 mV cart. Leaving theory aside, I've heard it w my own ears in my system and in doug's. However, my Ren Mk2 had two phono inputs, one for MM and one for MC. Are you SURE you have the phono plugged in to the proper input. I also note from VAC's website that the newer Ren MK3 can apparently be configured for 2 MMs; is it possible that yours is a late model Mk2 that is set up for MM only despite there being an MM/MC switch (their picture of the back panel of the Mk3 shows the MM/MC switch or dial and a loading dial). My Mk2 did not have externally adjustable loading but yours apparently does so its not a stretch to think it is set up similar to the MK3 on the website. If you got it new, check w your dealer; if not ask VAC to check their records using the s/n of your exact unit. If it was purchased used, its possible that the gain was customin=zed for the initial purchaser who might have had a v high gain amp or v sensitive speakers. I'd be very hesitant to lay this on the VAC's phono stage (gain or otherwise). The VAC h
My VAC is the latest Sig. MK2a, it's only a couple of months old purchased "NEW".

My friend "Rickmak" was nice enough to come by earlier today and completed the initial set-up which was really appreciated. Everything is brand new, Stealth Hyperphono cable, cart, arm with no hours including the phono stage of the VAC unit so it's now time to just chil and put some hours in and then Rick will come back to re-ajust.

There was a bit of an issue with antiskating but that has now been taken care of, Rick can tell you what the culprit was.

I'm looking forward to doing some listening.

THX Rick.

Doug: Centering the coils is why Immedia suggests letting the cartridge sit on the LP while using the Audio Physics fluxbuster.
