-   -   cartridge for RB251? (http://www.diyaudio.com/forums/analogue-source/165862-cartridge-rb251.html)

Why no DL-103
 
Am listening to Bill Evans thru a RB-250 and DL-103 as i type this.Added two - 2.5g weights plus a bit of BlueTac between cart and headshell. 2.5 grams VTF leaves the standard small counterweight at the far end of the arm ,anti-skate is set at about 1/2 gram. Plays everything on the HiFi News test disc.Most of my records are warped and this combo doesn't seem to have any particular problem tracking them.
I will admit it probably took a good 50 hours before my ears were used to this arm/cart. My experience with this cart is it does sound a lot better thru a SUT @40ohms compared to just feeding it into a 133 ohm MC gain stage.Initially had the arm set high - needed to bring it down dramatically to where the top of the cart was roughly parallel with the record surface (lined 3X5 " index card was helpful here) -KK was right.
My only real gripe is that it does seem to have a magic ability to pick up a nice matt of fuzz off of used records ( more time with the RCM).

OK I start to understand the issues of arm mass in combination of the cart compliance. That was helpful.
Still, not having any cartridge currently it seems better to go for a good combination at the outset.
I'm picking up my TecnoDec with the RB251 this weekend. I'll see what cartridge the guy uses, but he won't sell it.

I'm interested in trying the Doric on my P3 with the RB300 arm. Joachim, amongst your prolific number of circuits posted elsewhere there must be a suitable pre_pre amp for my tube preamp along with a solidstate version to compare to the tube using a line level input all of course with the powersupply. Sorry for being lazy i was trying to find them on the other thread but you are too busy!! :D

Ps used Doric low hours on audiogon approx USD$600

I've ordered an Ortofon MC Salsa, from the data I've seen it should be a good match for the RB251. Any comments anybody?

I think that is a good choice. In the old days i was a happy owner of an MC20.
I like that your new Cartridge has a fine line needle. Needs really good adjustment though.
The parameters ( 0.35mV, 7 Ohm) are not much different from my Lyras so my phonostages will work well. Compliance is ok too for the Rega.

Yes fine line needle. VDH would probably kill me if he knew ;)

In fact Dr.Weinz from Idar-Oberstein made the first "fine-line" needle. It was called the "Paroc". Long before Van Den Hul.

Figures, living in the middle of (semi) precious stone country.

Yes, sadly he died much to young. Idar - Oberstein is still the center of precious stone grinding in Germany.

These carts I have found decent enough with an RB300 (so they should work just as well with a 251):

* Goldring 1042 - very sensitive to phono amp capacitance, I had best results with 120p (+ cable capacitance). Nice round and full sound, lots of "slam", wide soundstage.
* Ortofon VM Silver - same league as the 1042, but different sound. Fritz Gyger 70 stylus, needs careful setup. Hardly any audible inner groove distortion, very well-defined (if somewhat small) sound stage with pin-point imaging. Slightly bright.
* Denon DL160 - budget cracker. Good stylus with little inner groove distortion. Extremely large sound stage with good tonal colours. Not the most "musically agile" cart, but also never completely disappoints. Low output MC, works with standard MM stages. Input impedance should be lower than the normal 47K, in my system 3K worked great.

I did not like the 440MLa (seemed to trigger arm resonances) or the Benz Micro Gold (dito).

Best,
Oliver
