Dear @lewm @neonknight : Appreciated your concern about me. I just decided left the analog Agon forum for a while due that seems t me that almost everything that we as MUSIC lovers and audiophile need to learn already done and as my posts in this forum I found out only repetition of other gentlemans posts ( exactly as mines. ), A few years I had the necessity to " invent " new " threads " that I posted looking to follow leraning and it happens that way.
I'm posting, time to time, in other Agon forums ( out og Agon othernet forums are only more of the same, nothing attractive. ).
Suddenly I read the title of this thread that has interest for me but was a little disappointnted for several reasons.
one of my reflexions on the thread came from what the OP posted because seems to me that he is more interested in hardware/tech than in the MUSIC reproduction.
For what he showed in the forum he is an almost analog roockie and even his experiences with cartridges comes from two MM cartridges one of them not only a vintage but ceratinly not a truly superior vintage quality performer with that Shure Type 3 and the other an almost entry level AT cartridge. Ok anyway those are his experinces. He posted:
" I’ve never even owned a Moving Coil type. " but even all those just at the start of second page of his thread decided for the DS Audio optical cartridge.
Why? because:
" My reasons for going DS Audio, and the DS003 in particular, include:
3 -The very low effective tip mass should enable better tracking than other cartridge types "........................."
With respect to him I tink no one of his reasons can be proved by him, example:
the tip effective mass for the Technics EPC100CMK4 is 0.005 mgs and for the Micro Acoustic 630 only 0.0015mg even the Empire 4000 D# is even lower and tracks at 0.25 grsms in VTF as the ADC 26 and the OP is nt taking in count the cartridge compliance that between other things almost defines the cartridge tracking abilities and in this parameter the ADC is 50 Cu
@richardbrand could you tell us if your DS Audio outperforms the cartridge FR Technics ( I named it ) specification? :
" It is a moving magnet one-point suspension with “ all HPF core, precision ground finish “, the cantilever is pure boron tapered pipe with a TTDD ( Technics Temperature Defense Damper ), the magnet is a Disc-shaped samarium-cpbalt with (BH) max=30 MG . Oe, the stylus tip is a especial linear elliptical stylus, with an effective moving mass of 0.055 mg. ( please don't ask what means these Technics propietary " cartridge design/build " characteristics: I don't have idea yet. )
Frequency response: 5 Hz- 120,000 Hz "
In the other side @dover forgot the Victor L1000 ( similar to the AT 1000X ) that I owned and at least other two " innovative " cartridges: The Nagatron ribbon cartridge:
" is a true ribbon cartridge, quite similar in operation to the transducing principle of the ribbon microphone. However, the less-than-full-turn metallic ribbon "coil" acts in a magnetic field not unlike the standard multi-turn coil commonly used in moving-coil cartridges. Its frequency response is not affected by wide variations in resistive and capacitive loading. An important feature is that its output is inherently phase linear.
he ribbon design concept does not rely upon varying the magnetic field in order to induce a voltage. Instead, the mag net is fixed, and the two flat strands of metallic ribbon (one per channel) move in direct proportion to the stylus-tip motion within the constant magnetic field. In this way, magnetic flux density is always constant and directly proportional to actual stylus-tip velocity. "
The other one are the Micro Acoustics electrostatic cartridges. He re you can read about:
Micro-Acoustics System II Product Catalogue | Vinyl Engine
click on " brochure " and in " the System II phono cartridge ".
I owned or still own all those cartridges but the ribbon one ( but I own the Nagatron 9600 and the 350 VDH. Btw, Dr. van DenHul reference cartridge is nothing less than the Technics MK4 and a gentleman in this forum with a top analof front end posted here that that Technics outperformed his Lyra Atlas: Go figure! what I'm talking about ) and you can get in the second hand maret in Japan and you can be sure that any of them outperform the DS Audio and are a challenge for any today very top LOMC cartridges.
I wonder other than real MUSIC against which cartridges you will make comparisons with the DS Audio other than the Shure/AT mediocrity level.
Obviously that's only my opinion than several times just do not like the gentlemans in this forum.
Regards and enjoy the MUSIC NOT DISTORTIONS,
R.
