Optimal loading for the Orpheus

"In my rig, there is really no easy way to change loading"

There is no such thing as not having an easy way to change loading. Anyone can have infinite ability to load a phono cartridge any value below 1000 ohms. All you have to do is modify the interconnect from tonearm to phonostage. I soldered in a female RCA using jumper wires at each cable male RCA connector. Into this I plug in a male RCA with the resistor of choice soldered from positive to negative.

After experimenting, you could simply solder the high quality resistor of choice right across the RCA connector (from Positive to negative) on the cable.

Again, all you have to do is set your phonostage to a know value and consult the chart for the parallel value. Or if your good at math, use the formula.

If you consult a resistor parallel chart, you'd learn that a phonostage set at 47K + a resistor of 1K equals a loading value of 979 ohms. 47k + 250 ohms equals 249 ohms.

As asked,the internal impedence of the Orpheus is 2.5 ohms.This is an astonishing figure,that only(as of now) the Air Tight PC-1 matches,though the Air Tight may actually be better,in this measured parameter.I am not so sure about the PC-1 vs "O" on an overall comparison though.In truth the "O" is just SO good that I am currently in the "could care less" state of mind.

AMAZING in virtually every way!Sorry for this sort of over the top post,but it SO outclasses my beloved "V" that I literally "need" to post this!...As to the "V",I had previously owned the Temper and Temper Supreme,and the "V" absolutely was the best of the lot!I loved it,in every way.Yes,it was/is sensitive to set-up,but before I upgraded to the "O" I was just SO happy,that I sincerely questioned why I should spend the extra money.Though I know the "O" is far superior,the "V" is still an amazing cartridge!Speed/detail/and much more authority than some will let on.

Yet,the "O" just put my jaw on the floor,it is totally astounding!!This absolutely "needs" to be heard to make any sensae at all!The "O" wipes the floor with the "V",in dynamic terms,and has far better tonal qualities.
Please don't take this as any negative "shot" against the "V",which was amazing in resolution,detail,balance and had fabulous stage depth and presence.To get all it has to offer though,one really MUST experiment ALOT with set-up variables as well as having a group of reliable audio friends to reinforce these impressions.

I am ONLY talking in the frame of Transfiguration designs,as I have heard almost all competitive designs and love them all...Almost! -:)
Good luck.

Reb1208,

You are right, I could make different loading plugs to experiment. That is a very good idea. I think I will get some high quality low wattage resistors for this purpose. Still, once I selected the permanent resistor and hardwired my unit, I would have to go into my unit and disconnect one leg of that resistor to then do further experiments (I have hardwired a resistor in parallel to the back of the RCA jack). This is not quite as easy as spinning a knob on something like the Manley Steelhead.

Sirspeedy said about the V:

IMO, more so than any cartridge I've ever owned. To the point of it being a real PIA to deal with cause you really have to keep after the darn thing. And I'm not sure really why this is.

For parallel resistors you need not be that good at math:

1/R1 + 1/R2 = 1/Rsum

1/47000 + 1/1000 = 1/979
