Replace a 0.5 mV Grado Reference Sonata 1 for a Dynavector-DV20X2-H 2.8 mV ???
I'm
using an Oracle Delphi mkII, with a Rega RB-300 arm (modified), wired with
Discovery's lockable interconnects, into a 2 box Audion pre-amp (built in phono
stage) using 4 Siemens E88CC 6922 tubes.
Lets start with the Grado hum (which I may add IMHO the support at Grado was
virtually "Zero").
The hum is faint, but still audible, especially considering that with tax & installation the better part of a grand Canadian went out the window; so lets just say the hum is totally unacceptable. Which is too bad, because outside of the faint hum & gutless gain (more on that to come), it's a flippin nice sounding cartridge.
The other beef is that my set-up guy selected the wrong Grado to pair with my Audion pre-amp. Apparently the Reference Sonata 1 came with either a 4.8 mV gain, or a 0.5 mV gain. His reasoning was that the 0.5 would be quieter, and it is, but the problem is I have to turn up the volume to 3 o'clock to get the gain I want.
Qu #1: Does anyone out there know the specific gain difference in % between a 0.5 moving iron Grado & a 2.8 MC.
Qu #2: Anyone ever experience "HUM" with a Dynavector-DV20X2-H 2.8 mV on a Rega Tonearm?
Qu #3: Does anyone out there have experience using Dynavector-DV20X2-H 2.8 mV with a tube pre-amp? What are your thoughts?
@thehorn The phono input sensitivity spec is listed at 2 mv. You need a mm cartridge with 2 mv or more ! http://www.audion.co.uk/pre-amps/Premier%202-0%20line%20phono.html |
In reply I do own a Grado Reference Sonata wood body (high output MI) I use mainly on a Thornes TD160. I recently sold the 10X5 to my brother along with my Pro-Ject Xtension 10. Now I run a J.A. Michell Gyro SE with the 20X2L mounted on the latest generation Techno Arm ll (Rega based RB202). "You need a mm cartridge " Yogi, A hi output MC will work just as well as a MM and any high output moving Iron also. So the OP has lots of choices. Matt |
