Tranfiguration Orpheus description

Dear friends: As the " actors " of this controversial cartridge test post/posted about the situation has more fail and misunderstanding, example: Doug post that the O set up was made with the usually " VTA madness " that he likes and in other post Andrew told us: +++++ " we did not make large enough changes( speaking of VTA ) to evaluate the cartridge with a parallele...." +++++

Between other things that Doug or Andrew mentioned is how they match the volume gain for every time that they change the volume gain with each cartridge this volume gain was exactly for both cartridges due to its different output.
This subject is extreme critical because any small difference in the SPL is detected for our ears/brain and that small SPL difference could give us not small changes in the frequency response that could alter in a very sensitive way the sound perception.
Other issue that is related with the changes in the volume gain setting is that normally almost all the preamps change its frequency response when change the volume pot position and this alter the quality sound reproduction for both cartridges but in different way. Here the designer could explain us about in the Doug's unit.

I think that Doug don't read yet what I aked him: the inverse RIAA eq. deviation from 20 to 20kHz in his unit, this is extremly critical especially with top cartridges like the O and U. Here again I ask to the designer for he can give us his unit info: important!! ( It's curious that Mr. Doshi don't comes yet to this thread when we need very important information about his unit and for understand better what happen with this controversial cartridge test. I'm saying this because I read posts of Mr. Doshi in other lesser threads. )

All these subjects ( including others that I posted here ) are important and are related with what Larryi posted: +++++ " I really can't see how any phono component can be evaluated other than as part of an evaluation of the complete system " +++++ and Larryi if you don't mind: not only a phono component but any audio device.

Regards and enjoy the music.

Friends: Sorry for sentence mistake: " Between other things that Doug or Andrew mentioned ", it should be: not mentioned.
" yet what I aked him: ", will be: asked him.

Hi Raul,

I am responding to you because part of me does believe that you are genuinely interested in helping to sort out the missing pieces to this puzzle.

I have conversed with Nick recently regarding other things completely removed from this thread. He is pretty busy these days with his main line of work. I don't happen to have the specs you are asking for either. But I don't think it is anymore "curious" that Nick hasn't responded than it is that Jim White, or Mr. Hagerman or any builder has ever responded to any thread as full of speculation as this thread is.

Be safe and happy,

Dan

I think it unlikely that Nick would post on a thread as pointlessly contentious as this one. Unlike many of us, he actually has a life! ;-)

Neither Andrew nor I have anything to apologize for, and it's a waste of time responding to people who don't read what we wrote before posting criticisms. For example, I've stated at least three times that we played the O with slightly positive SRA, but I'm still being told that we should have done what we did, or how to do what we did. Has everyone gone blind?

Nsgarch launched this thread to discuss the Orpheus. I have nothing more to add unless I hear one again, and I'm unlikely to share it here if I do.

Doug

Dear Doug: Sorry to disturb again. My last post was only to state that there are differences in what Andrew think was the O set up and in what you state about. This Andrew post confirm it: +++++ " We did not evaluate a broad range of VTA in Doug's system . Paul tried several setting within a small range but I beleive all of the settings put the arm lower than parallel. Although, I preferred one of these settings, we did not make large enough changes to evaluate the cartridge with a parallele or slightly elevated arm. " +++++, I can tell you I'm not blind and I'm not doing criticisms only for doing that but for trying to help to understand the results of that cartridge test: that's all !!!!

Btw, those three subjects: precise volume gain, frequency response with changes in volume gain and RIAA accuracy, are crucial in any two cartridge test and are very important to understand the results and if you can it will be nice that you share the info with us.

Doug, it is normal the reaction of all the people ( including me ) in this thread when the test's results are controversial like this ones, be patience.

Regards and enjoy the music.
Raul.
