Pani ... New ART-9 up and running ...
Chakster, Thanks for the response.  The circuit looks very simple, which is good. I have no idea why they call it a "Diamond" transistor, but that's marketing-speak anyway.I wonder a little bit how they achieve two different gain profiles (one for... 
Pani ... New ART-9 up and running ...
Dear Pani, My apologies. I knew full well that it is Chakster using the JLTi.  That was just a bit of brain fade.  Perhaps Chakster will respond to my question: What happens if you don't plug anything into the load jacks on the JLTi?  Does it pres... 
Adding mass to a tonearm
I tend to agree with Pryso.  Look at the Technics EPA250 tonearm: The optional arm wands with lowest effective mass are all straight pipes with a tiny fixed headshell.  The arm wand with high-ish effective mass is an S-shaped pipe with provision f... 
Pani ... New ART-9 up and running ...
There are many, many other phono stages (besides the JLTi) that also allow the user to tweak the resistive loading by one method or another.  In my opinion, this is an essential feature of any "high end" phono. If one only wants to convert from a ... 
Adding mass to a tonearm
As someone else wrote, adding mass to the headshell most certainly DOES increase the effective mass of the tonearm, by a factor roughly equal to the added mass, in grams. (As you move down the tonearm toward the pivot, the effect of adding mass at... 
Phono preamp power cable not long enough. New wall wart or use an extension cord?
rhljazz, If what you say is true, have you had any second thoughts about the Shunyata?  There's no technical reason why the Shunyata would not work well with a wall wart power supply or at least AS well as it works with any other component you plu... 
Who needs a MM cartridge type when we have MC?
As someone who had his Grace Ruby rebuilt by SS with their OCL tip, I can attest that indeed the new stylus shape (or something else attendant to the rebuild) has made for a very noticeable improvement in the performance of the cartridge.  For a "... 
6922 Tubes!
Wiki says that cryo treatment of "metals" occurs at temperatures less than -190 degrees C or -320 degrees F.  N liquifies at -195 C/-320F.  At temps below -210 C/-346 F, LN freezes.So, it does appear that the benefits of cryo treatment can be achi... 
6922 Tubes!
Geoff, Is your information about the putative benefits of refrigerator and home freezer temperatures based on real world direct experience or on what you have read elsewhere?  Back when I did some reading on the physical effects of cryo treatment,... 
Who needs a MM cartridge type when we have MC?
Dear Chakster, Your dissection of the lineage of Grace cartridges is very informative.  Thank you for that.  But you imply strongly that one can know how a cartridge will sound based on knowledge of its stylus shape.  One would only wish this were... 
The Palladian-A step beyond
Flieb, I wish I knew what you were trying to say in your comment on males v females.  And then the attribution to Neobop.  Is this something once written by Neobop?Dare I respond?  No one said or says that males and females are precisely equal bio... 
Pani ... New ART-9 up and running ...
I don't think my throwing one more set of subjective opinions into this mix would do anyone any good, least of all the OP.  However, Chakster, because you've got a ZYX 4D, do not assume you know how a UNIverse sounds.  I don't own and have not hea... 
Audio Note SUTs - Are they worth the money ?
I am not sure that ALL Audio Note SUTs use silver-wired transformers.  For those, you pay even bigger big bucks.A SUT or any other transformer, has no inherent impedance at all. Transformers merely reflect the impedances of whatever is attached to... 
Audio Note SUTs - Are they worth the money ?
With the ART9, you don't need much additional voltage gain from the SUT in order to drive an MM phono stage, maybe 10X would be overkill, in fact. So, if you're interested in doing this in a scientific and cost-effective manner, so far as that is ... 
Fidelity Research FR-64 vs. FR-54
Raul, You just couldn't resist the dig about distortion-lovers, could you? Some day you may wake up and realize that your consciousness is not the only one in the universe.  I hope that happens for you, soon. We are not all figments of your imagin...
