Which Mono Cartridge at around $1,300.00?


I'm in the process of upgrading my well cared for Thorens TD145. I started by soldering in WireWorld phono cable along with getting a basic tune up. I want to replace my Grado ME+ mono cartridge with a substantially better mono cartridge. Currently, the tone arm is stock. My records are classical (orchestral, chamber, vocal, etc...) dating from the 1940's and 1950's so I've been cogitating on the Ortofon SPU Mono GM MKII or a low output Grado (i.e. the sonata reference 1). My phono stage is the ASR Mini Basis Exclusive. All or any suggestions would be greatly appreciated.
Thanks!

Thanks Jonathan and everyone else for that matter. The $1,600.00 price tag for the Dorion Mono comes from a search engine entry and could be due to the fact that it's out of production. I wish not to cite the name of the website out of discretion. Also, I'm sorry Lewm for not clarifying better but my cost comparisons were within competing mono cartridges, those which clearly state that they are 'true' mono cartridges (i.e. the Lyra) and those who do not. This I realize, is still very vague since I am not giving the names nor the technical specifications of those cartridges that I am cross referencing. I want to say however that coming from a pragmatic and aesthetic description of qualities that I've read from the various competing mono cartridges, the Lyra mono cartridges are the most appealing. All of my records are from the mid 1940's through to the late 1950's. Many of these platters, for example my ARCHIVE PRODUCTIONS vinyl, weighs in at 180 grams and many have never been played. Those that I own with the seals broken, were most likely played only a few times. The rest of the vinyl that I own which I'm willing to put on the turntable, might have a few surface marks but will not effect the sound. I'm very fortunate to have come across classical mono vinyl obtained in estate sales and then sold to a friend of mine who in turn sells them to me for a song.
Goofyfoot: Before you pay big bucks for any mono cartridge, you may want to try a real mono cartridge for low(er) cost, such as Audio-Technica's AT33MONO. IOW, dip your toes in the water for a nominal fee.

You can see that it has a horizontal coil, which means no sensitivity to vertical modulations ("real mono"). The connection diagram in the data sheet suggests that there are two identical coils, which IMO is the best choice for a mono cartridge that will be used in the context of a stereo audio system. Part of the data sheet mentions an "elliptical stylus tip), while the specifications section mentions that the stylus is round. Hmmm. The Japanese data sheet specifies a nude spherical stylus, so that is probably what it has. Vertical tracking force is a bit on the high side (2.3~2.7g), but at least it isn't obscene. The datasheet mentions static compliance, which to me suggests that there is vertical compliance.

The 0.35mV output of the AT33Mono may be a challenge if you don't have a phono stage that is comfortable with low-output cartridges, and the price may still be higher than what you would prefer, in which case you could look at the AT-MONO3/LP (not the SP version, which is designed for 78rpm shellac discs).

I haven't been able to find the data sheet, but according to LP Gear, the stylus is conical, output voltage is an easy-to-use 1.2mV (@5cm/sec.). Again there is mention of static compliance, which implies that there is vertical compliance, and the vertical tracking force range is 1.25g~2.5g, which should be no problem to accommodate.

For a decidedly more vintage approach, you could consider Denon's DL-102.

This clearly has only a single mono coil, and you may run into hum issues if you connect this to a stereo phono stage in the same way that you could do for a stereo cartridge. I suggest connecting this to only one channel of the phono stage.

OTOH, the output is a generous 3mV (@5cm/sec.), which should be enough for nearly any phono stage.

The vertical tracking force range is 2-4g, so it is getting a mite heavy, and AFAIK the DL-102 has no vertical compliance, so you should not play stereo LPs with it. Actually I wouldn't play any of my mono LPs with it either, but I wouldn't mind listening to someone else's irreplaceable mono LPs with it - grin.

I have a Benz LP-S MC stereo cartridge on a Graham Phantom Supreme. My second tonearm is a Schick 12" tonearm with a Miyajima Premium Mono BE cartridge (special low output version). I run it it through Bob's Devices Cinemag 1131. Use both old 1950s mono albums as well as new reissued mono vinyl. I love the Miyajima. Big, bold, meaty sound, with extension and transparency (not dark sounding at all). I love both my cartridges...both excel. The LP-S is incredible, especially for capturing everything and put it out there in a 3d organic manner. But, the Miyajima, while not as spacious as the Benz, excels in drive and sheer heft of musical impact. I'm glad I have both. If looking for mono, the Miyajima Premium Mono BE coupled with Cinemag 1131 is the bomb. And Robin Wyatt the distributor is A+++++++ in my book -- I speak from experience. He has gone above and beyond to make sure I'm taken care of both on cartridge and SUT. He is white glove treatment all the way. Order direct from him and you won't be disappointed.
My skepticism lies in the idea of purchasing a MC cartridge below a standard price point. I'm not skeptical of the Miyajima Premium Mono however but nevertheless am entertaining the idea of a slight upgrade within a MM mono cartridge until I'm capable of breaking the bank. Podeschi, would you mind giving me that distributers contact info and URL?
Jonathan, re: the Denon 102. This quote comes from an on-line information article -

"Basically, the DL-102 is a high output MONO moving coil cartridge which has incorporated both vertical compliance and a 0.7 mil radius stylus, making it compatible with stereo LP playback and is intended for playback of both Mono and Stereo Records."
