Who needs a MM cartridge type when we have MC?
Nope. I was looking at the spec sheet for the CPP-1.  However, I agree that the CPP-1 does not contain an RIAA correction filter.  125R would be little different from 100R when it comes to loading a phono cartridge. Specifically, I would expect th... 
Vintage DD turntables. Are we living dangerously?
Thanks for your note regarding the special dangers associated with using the MC2000, Raul.  I neglected to mention that the TI Shield contains iron.  After observing the problem with the MC2000, I was able to demonstrate to my own satisfaction tha... 
Who needs a MM cartridge type when we have MC?
I went to the ZYX website, finally, to get more information.  There they do say that the load R = 100 ohms.  But I am confused a bit more, because on the ZYX website they give a spec for accuracy of the RIAA correction, which per se does not make ... 
Who needs a MM cartridge type when we have MC?
Thanks for the info on the ZYX. I was not even aware such a product existed these days. Neither the so-called "review" by Arthur Salvatore, nor the  blurb on the Sorasound website say what is the value of the input resistance on the ZYX.  If it's... 
Who needs a MM cartridge type when we have MC?
Chakster, For a load resistor, I would choose the nude Vishay (best and cost the most), then the Audio Note tantalum type, then the Caddock TF020 (which can be purchased from M Percy and cost the least).  The differences among them are small, but ... 
Who needs a MM cartridge type when we have MC?
I've just read the last few months' worth of posts.  As noted by Fleib, I think, I am one of those who found that my 980LZS sounded best loaded at at least 1000R and above.  It sounded really dull at 100R.  Do not judge it at that load resistance;... 
Hated my Pro-Ject Debut III looking for another budget option. Kind of thinking Thorens
IMO, Cheap cartridge on a good turntable/tonearm will beat an expensive cartridge on a cheap or poorly designed turntable/tonearm, every time.  So, stretch out to get a good turntable first of all, is my advice.  Surprised no one mentioned "vintag... 
Why the lack of Virtual System postings?
And then there's mono.But seriously, Halcro, can you not remove some of your old photos that may no longer depict your system as it is currently, and thereby sneak below the 50-photo limit?  You've reminded me that I am derelict in keeping my syst... 
mc cartridge loading
One of the most commonly used phono input tubes is the 12AX7 which has a very large Miller capacitance, given its high mu factor, albeit nowhere near to 10,000pF!  How did AcousTech manage to "achieve" that? 
Vintage DD turntables. Are we living dangerously?
Geoff, I will have to chew on that mouthful for a bit, but can we agree that EMI has the property of "frequency"?  Assuming you would agree, then in what way would EMI differ from "low frequency magnetic field(s)"?  Permanent magnets per se do not... 
Vintage DD turntables. Are we living dangerously?
Geoff, I would have thought that "EMI absorption" is but a more concise term for "low frequency magnetic field absorption".  Especially since my reading also tells me that the forte of mu metal as a shield is to block or contain EMI, rather than R... 
mc cartridge loading
The 10X Rule is important mostly for achieving a flat frequency response within the audio frequency range (up to 20kHz), when two amplifying elements (e.g., preamplifier and amplifier, CDP and preamplifier line input) are in tandem; the input impe... 
mc cartridge loading
Right now, on two different turntables, I have set up a Koetsu Urushi, in one case, and an Ortofon MC7500, in the other, both looking at a 47K load.  Sounds really good, but not necessarily better than into, say, 1000R or even 100R.  (I do think I... 
Vintage DD turntables. Are we living dangerously?
Aaarrrggghhh. You’ve done it again, DDrive. Stop already with the "motor vibrations going up into the spindle". This is not really a problem with a direct-drive turntable. As I mentioned on the other thread, DDs are subject to bearing noise, just ... 
Best platter mat, especially for DD turntables
Ddrive, I am sorry to hassle you, but you are incorrect in drawing any distinction between the SP10 Mk3 and the Mk2 (each of which I either own [Mk3] or have owned [Mk2]), when it comes to motor "noise".  The distinction you make between the two i...
