Is setting VTF on Graham Phantom fussy?
I just checked and the picture on the Graham site now shows the upgraded magnet (flat face). However, if you click on the Stereophile review link, you will see a picture of the older version arm with the pointed magnet. 
Is setting VTF on Graham Phantom fussy?
Hello Sirspeedy:How are you? I just returned from extended trips to AZ and FL, sorry for the delay in responding to your inquiry on my virtual page. Do you know the starting serial number of the Phantom with the upgraded magnet? I spoke to Mr. Gra... 
Tube amp speaker output 4 ohms VS 8 ohms
Robr45 is correct. You should experiment with both sets of connectors. For example, ARC tube amps such as the D76A, the Classic series and the VT series (VT100, etc), in many cases, sound better when driving 4 ohm speakers from the 8 ohm amp conne... 
Biamping with tubes and SS: Input sensitivity key?
If you use an electronic xover for biamping. the issue of input sensitivities of the amps will not be that important since the levels can be adjusted via the xover. 
Shunyata VS Richard Gray
I have both. I use the Shunyata 8 for the front end equipment. I use three (3) RGPC in paralell to power the amps and subwoofers. I think the RGPC may work better with high powered applications. If possible, you should experiment with different co... 
Basis Debut Mk v or Walker or Brinkman ?
Congrats Strapper211:It seems that you were already predisposed to buying the Walker, but you needed some reinforcement: hence the thread.The Walker is indeed an excellent turntable. However, I would be curious to know how it compares with the Bas... 
Oracle Delphi MK IV - Delrin Pillars Anyone?
I own the Delphi MKV SE. I am in a positon to comment on the changes as I made this upgrade on my MKV which came with the steel pillars. As I recall, The improvement in sound was musically significant: quieter and blacker background, which allowed...

Basis Debut Gold Standard Mk V or Sota cosmiii
Hello Steve:Greetings!Have you tried the upgraded Phantom bearing?If not, you would be surprised at the level of improvement resulting from this seemingly minor change.George 
Basis Debut Gold Standard Mk V or Sota cosmiii
Both are very good turntables that will provide top notch performance and reliable service for a long time. With the Benz ruby/Graham, the prices are about comparable. I think the Basis is a fine looking turntable. If I had to choose I would go fo... 
New Phantom Bearing
Yesterday evening, I installed the new bearing. Since then I have spent about 16 hours listening to my system. Before describing the sonic changes, I would like to add a few notes.I had to return the original upgrade bearing to Graham as it was ab... 
ARC VT100MkII
The VT100 MKII is a "classic" amp. It is easily one of the best sounding amps ever made by ARC irrespective of price. I am using it coupled with the LS25 MKI preamp also. Its strengths include: dynamics, huge soundstage, midrange purity and beauty... 
Oracle Delphi vs. ??? fill in the blank.
The Helikon likes to be loaded down quite a bit (47k is too lean sounding). I am using 100 ohms with my ARC PH2 without loss of air and treble response. I am getting a rich (not overly warm) tonal balance in my room. However, I can vary the degree... 
Oracle Delphi vs. ??? fill in the blank.
I am currently using an Oracle Delphi mkV SE (turbo PS and granite base) with a Graham Phantom/Helikon combo. In absolute terms, I cannot rate the Oracle versus all the available turntables currently available. However, in musical terms the Oracle... 
Helikon LOADING
Jeff Jones:The complex impedance is given by:Z = R +iX.Your formula for the real impedance (amplitude, etc) is incorrect. The amplitude is given by the square root of the complex conjugate product, ie:|Z|**2 = ZZ* = R**2 + X**2** denotes exponent,...
