Want to upgrade my cartridge from 2m blue to black

@jji666 why do you think a tube phono stage (especially a cheap one) is a good idea ?

A few responses:

(1) I introduced this as a pro-fun suggestion. Tube rolling, especially if one has never done it, is pretty fun. Plus with a relatively inexpensive piece of gear the stakes are low.

(2) "Cheap" is in the eye of the beholder. The OP’s budget implies "cheap" relative to many posters here, but you can get a phono preamp for well less than $100 that technically does the RIAA curve correctly (not that I would...). A $200-$400 phono preamp can be pretty decent and about what is appropriate as a mate for the turntable.

(3) Audio is a journey. While I am usually of the mindset that when you have the upgrade itch you are better off focusing on one big leap upgrade versus a bunch of smaller purchases, analog/phono based upgrades go steep pretty quickly. I was thinking that tube rolling would be a fun experience and allow for an exploration of various sounds based on tube etc.

(4) I did say that the MS-12b is not quiet, so I can see your point. However, short of power tubes that can be much, much more expensive, I found that tube rolling with a phono preamp made the greatest difference relative to rolling in other gear. Your mileage may vary, but that was my experience.

(5) Note the OP's name...

Point being, if the OP wants one of those experiences where he/she wants to relisten to all the vinyl through a new lens, this would be a good way to do it. Spending only on a cart upgrade as with the current TT, and the OP doesn’t have the budget to really do a great TT upgrade and new cart, would likely top out performance based on the TT ceiling. A tube phono preamp is a way to try out different sounds and enjoy an analog feel with old school tubes on that budget.

Chakster - I'm going to try that Astatic MF100 on your recommendation - I do most of my listening with top flight MC - have curtly installed A90/Lyra Olympos/ Lyra Atlas/ Ortofon Cadenza Black/ and the 2M Black on a "red" body :-) - you know the thing that can't be done

Good Listening

@pbnaudio good, remember it was one of Raul’s favorites back in the day in MM thread. For higher price that seller may have Glanz MFG-610 LX (you can ask). Glanz is better (different cantilever and different tip), but for double price. The seller is legit, some other audiogon members bought stuff from him (me too). But for whatever reason you can always return a cartridge under paypal buyer's protection with no loss. 

I think @chakster is a little ignorant when it comes to this issue. I've upgraded tone arms (which a TT upgrade would do) and used the same cart. The sound improvement was significant. Putting a shibata tip on an ortophon blue is like driving a boom box with a 300w amp. Jus' sayin'

There is also an Astatic mf300 on ebay, NOS including headshell for $599.
No idea if that is twice as good as the mf100?
