Marantz TT15/ Clearaudio Satisfy for MC carts?

I’m going to make a very radical suggestion for an audiophile. You heard the Virtuoso cartridge at the dealer and described it as “very impressive”. How about buying what you know you liked rather than buying a pig in a poke? Does this make any sense? The stock cart is a great starting place and you had the benefit of audition. You will have to replace it in a couple of years anyway and then you can screw around more. IMO

Absolutely agree...I had no issues at all with the Virtuoso. I have very little experience with MM carts, but this one was quite positive. It's more about choosing the right table and arm. And it's my bad for not making it clear that I'm not 100% set on the TT15. But if I do go for it, I'm not sweating the cartridge at all. Perhaps this is a naive outlook, but at < $1800 for the TT15 package,  I consider the Virtuoso a throw in. Beyond that, there is always next month, next year, and the year after...

A lot of turntables that come with a cartridge have "throw in" cartridges, but I would not describe the Virtuouso as a "throw in".  It's a very capable cartridge.  I currently have mine mounted on my souped up Technics SL1200 MK2.  

I would go so far as to say that the cartridge is the best thing about that turntable, followed by the tonearm, with the turntable itself being a little on the cheap side. 

There isn't much mass to the platter or plinth and the feet aren't that great.  The motor can have a tendency to slide around, which will affect speed, or introduce noise if it comes into contact with the plinth.  The power button is on the side of the motor, which sits under the table.  I'm not sure if the TT15 is the same as the Emotion in this regard, but there are two grounding wires, one that loosely attaches under the center spindle in addition to the tonearm wire.  You might not need to use the second wire under the spindle, but if you do it's a little fussy to set up since it connects underneath the table.  

I put a thin sheet of sorbothane under the motor to isolate it and keep it from sliding around.  If you have a surface where it won't slide around, that may not be necessary.  My table came with the Emotion Aluminum Feet (should also work on the TT15), which are very nice. 

The only downside about the Virtuouso cartridge is that the cantilever sticks way out in front of the body and is very easy to unintentionally remove.  When/if you snap yours off, Andy Kim will replace it with a better one and you'll have an even better cartridge.

I am using SL1200MK2/4/6 TTables for a long time, love them much for reliability and performance, here is my OP:

1): you will get nice SQ by adding Audio Technica MM cartridge, I personally found  the best sounding one is Audio Techinca AT20! Other AT MM carts will work well too, to name a few: AT-150MLX, AT ML160/170, haven’t tried yet latest 740/760 series, but those should be similar. For best results I am using high end AT head-shells, LS/LH/MS series.

2): the best tonearm for SL1200 I tried is SL1200MK4, which is Technics own “audiophile” version of S shaped arms, and uses Titanium to dampen resonances.  MK4 TT arm has handy RCA connectors for exploring variety of phono cables. Latest original series SL-1200MK6 table arm is cool too, seems it uses less resonating not fully disclosed alloy, and better wiring, SL-1200MK6 has better main body dampening as well, so, that table is worth to try.

3): There is one improvement I would recommend if you hear inner tracks 60Hz hum noise, is replacing power transformer with better shielded / toroidal one. 

The Best MM cartridges are MP cartridges from Nagaoka. I have two TT and run the MP200 on my Clearaudio Concept and the MP110 on my Thorens TD145. Fantastic.
